Connect air dryer. Connection and operation of the pneumatic tool. For which the apartment needs air dryer

Drops of temperature and humidity both indoors and outside create uncomfortable conditions for accommodation in the apartment. The optimal output from such a situation is the installation of the air dryer. The industrial option is not noone, so today we will talk about how to make the air dryer for the apartment with their own hands.

For which the apartment needs air dryer

The most unwanted and unexpected guests in our dwelling are mold and fungus. Their disputes constantly hide around, but most of the time they are in a nozzle state, because in order to activate it requires certain conditions:

• humidity;
• high temperature indoors.

There is enough temperature above 20 degrees Celsius at a relative humidity of 80% so that you see the rise of the colonies of mold and fungi on the walls of the rooms. And why, in this case, for example, does your neighbor have no similar trouble? The answer is simple: the air temperature in all apartments is most often the same, but humidity may seriously differ.

Drying air

In the fight against the effects of dampness, you can, of course, significantly reduce the temperature in the apartment. But who wants to live in a constant cold? In connection with this, the optimal option is to install the air dryer.

Among other things, it will be guarded by the health of residents of the apartment. The body's immunity is directly depending on the humidity of the surrounding air: what he land is, the more difficult to multiply malicious bacteria and microbes.

Drain will also save you from the shripes on the windows.

Operating principle

Modern air dryers are represented by a variety of models that can differ significantly from each other. The first difference is a working volume, that is, the amount of water filtered by the device from the air. This parameter is measured in liters for the daily gap (24 hours).

To select an appliance with an optimal volume, consider the size of the room in which it will be installed. Pay attention to the price of equipment. The more the volume of the desiccant, the more expensive, but the service will be required less frequently.

Dehumidifiers are portable and stationary. The first mobilies, you can use them in different premises if necessary. Stationary are attached to the wall, their carrying is impossible, but they have greater productivity.

The principle of operation of the desiccant is based on changing humidity due to its condensation. The air comes out of the room using the fans inside the instrument. There, he passes through the evaporator, which is a radiator, the temperature in which is lower than the room temperature in the room. Moisture is condensed due to such a temperature difference.

The simplest air dryer scheme

Condensate droplets flow down and assemble in a special container. After passing through the evaporator and cooling, the air heats up and served in the outlet, where it gets back to the room is already dry and warm.

Note! When using such a desiccant, you need to make sure that the building has a high-quality system of forced ventilation, which supplies fresh air to the room and selects mixed.

Condensation Dryer Scheme

Such dryers are often used in the following cases:

• to prevent fogging windows in the premises;
• to improve the level of comfort of everyday life;
• when carrying out repair work.

Any finishing materials during the repair when using the dryer dried much faster. And the technology does not suffer at all: the temperature in the room remains the same.

Algorithm for creating the device with your own hands

Drainage of air is ensured by three simple principles:

• heating;
• adsorption;
• condensation.

It would seem that with the help of heating the easiest way to dry the air indoors. But in fact, no one will like it to constantly be in too hot apartment. Therefore, we will consider the following two options: adsorption and moisture condensation. Do despair based on these principles, you can independently.

Desiccant adsorbing type

Perhaps the simplest option that does not require large financial and temporary costs.

1. Take 2 plastic bottles. The volume of each is at least 2 liters.

   You will need plastic bottles of 2 liters.

2. The bottom of the first bottle is perforify with hot spoke or nail. Divide the container into two identical half.
3. In the bottom, perforated, part of the first bottle, place the second half so that it is directed down the neck. Be sure to turn the cork on the neck, having done in it a plurality of holes with a split selay.
4. Put any absorbent in the upper part of the design. The optimal version is a silica gel with powerful absorbent properties. Which are easily restored after drying the used substance. You will need about 250 grams of silica gel on one dryer.

   As a filler, use silica gel

5. Cut the bottom of the second bottle, fan the fan inside the tank, which will blow toward the cutting bottom. To do this, you can use a USB fan or cooler to cool the computer processor. Place the pressure node of the device in 7-10 centimeters from the cut bottom.

   As a fan in such a dryer, you can use a cooler from the processor

6. For a second bottle, put on the containing the adsorbent. The place of the joint thoroughly wrap the scotch for sealing. Twist the cover with the neck of the second bottle - so you will ensure air flow.

   Example Connection Parts Bottles for Desiccant

Thus, you will get a low and quite efficient device that can be easily powered by a USB connector or charging for a mobile phone. The fan creates a tributary force and drives the air through the silica gel, and the drained flow comes out of the perforations at the bottom of the design.

Desiccant of condensation type

This device is more difficult than the previous one, but the basis of the desired design is easy to find in each modern house. Roughly speaking, such a desiccant can be done, for example, from the old refrigerator.

Example of refrigerator air dryer

1. Remove the door with freezing and refrigeration compartments, dismissing the loop. Make it just because most models are equipped with removable doors.
2. On the dimensions of the removed doors, measure the plates of the plexiglass at least 3 mm thick.
3. At a distance of 30-40 cm from the edge of the plate cut the hole in which the fan will be mounted. Its dimensions must coincide with the protective grille of the pressure unit.
4. Place the fan, secure it with the grid with the help of screws. The device must work as a trimming unit, blowing the air flow inside the refrigerator.
5. In the upper part of the plate from the plexiglass, drill a row of holes. Their total area should be equal to the fan opening area.
6. Put in order a full-time condensate system from the body or modify it. To do this, combine the outer pipe above the compressor with the accumulative capacity of the polymer hose.
7. Plexiglas fasten with self-drawing on the place where the door of the refrigerator should be. To seal joints and insulate them, use self-adhesive tape or silicone.

Now you have only to turn on the refrigerator, running the fan before that. It will take place a little time, and the humidity in the room will decrease by 8-10%. If this homemade dryer will work for a long time, then besides the moisture, the room temperature will decrease.

Humidity control

How to solve the issue with humidity control? Factory air dryers are equipped with built-in control sensors over the temperature and humidity. And how to be in the case of a self-made device? You can use a thermometer, but it is optional and besides anything will say nothing about the level of humidity.

Use a hygrometer. It can be arrow or digital. You can buy it in many specialized stores. In addition, such a device is often provided in the design of some modern clock models.

The hygrometer will help you control the humidity of the room indoors.

Using the homemade air dryer, do not forget that too dry air can be harmful. After all, besides the pathoral organisms around us there are also useful bacteria, which also need moisture. The hygrometer will help you determine if there is a need to use the desiccant. If the humidity in the apartment reached a critical 80%, in which mold and mushrooms begin to actively multiply, boldly turn on the device. Pay attention to weather conditions: perhaps in some cases it is not necessary to use a desiccant, but a moisturizer.

As you can see, you can easily make air dryer yourself. Thus, another problem is solved - the use of an old refrigerator, which is sorry to throw away, and there is nowhere to do. Share with us your experience in draining the air in the apartment. Light you work and comfort your home!

Fig.7 Desiccant Device for Compressor

Desiccant device: 1 - Refrigerator compressor, 2 - capacitor, 3 - fan motor, 4 - evaporator, 5 - condensate separator, 6 - hot gas valve, 7 - refrigerant filter, 8 - capillary, 9 - pressure valve.

Fig.8 Diagram Device Device for Compressor

Desiccant Device Scheme: 1A - Air Entrance, 2A - Air Outlet, 3A - Conison Descent, 1 - Refrigeration Compressor, 2 - Condenser, 3 - Fan Engine, 4 - Evaporator, 5 - Condensate Separator, 6 - Pollution Drive, 7 - Capillary , 8 - Refrigerant Filter, 9 - Hot gas bypass, 10 - Air-air heat exchanger, 11 - Thermometer dew point, 12 - Fan switch, 13 - Condensate reset valve.

The compressor (1) compresses the refrigeration agent (gas), which enters the condenser (2), where it is condensed. If necessary, fan (3) is launched to improve the efficiency of the refrigerant. Condensate passes through the dewatering filter (8), after which it is expanding in the expansion valve located in the capillary (7). After that, he enters the evaporator (4), where the cooling process occurs. Advanced in the evaporator The refrigerating agent is absorbed and is compressed again by the compressor. The system is equipped with bypass refrigerant. Allows you to adapt the amount of the refrigerant in the system to the actual volume of compressed air passing at the moment through the dryer for the compressor.

This happens by entering hot gas through the control valve (9). The valve supports the constant pressure of the refrigerant in the evaporator, so that the dew point never falls below 0 ° C, which protects against the freezing of the refrigerant in the evaporator.

Desiccant for the compressor works in an automatic cycle. By default, the dew point is installed at + 3 ° C.

3.7. Movement of compressed air

The resulting compressed air in a saturated state enters the evaporator (4) (for compressor dryers from OP40 to OP80 to the main heat exchanger (10)), where the temperature of the dew point is cooled below, and then enters the condensate separator (5). In the separator there is a separation of condensate from air. The cooled air is returned to the exhaust pipeline to the equipment. Condensate is discharged through the condensate shutter valve (13), equipped with a time relay.

Drainage of air is carried out at the expense of the compressor through which the air flow passes. Then the air passes through the ring type filter, where it is cleared of carbon black and evaporation of oil fluid.

In the ring filtering device, the airflow is cooled, due to which part of the moisture remains in the chamber of the drying device.

After filters, air passes through the granulose powder to the inverse type valve. After it, he falls to the air charm of the brake mechanism, passing through the taps.

At the same time through the jaw and the removal, the air receiver is filling, which is used for regeneration. Cleaning the air flow and the initial removal of excess moisture in the annular filtering element contributes to an increase in the operation of the brake mechanisms.

Operating Rules

In order for the air regeneration device without failures, it is necessary to carry out its maintenance in a timely manner, according to the user manual. It is also recommended to conduct a daily inspection of the device for damage and defects.

In order to check the safety valve of the equipment, you need to tighten the hollow screw of the regulator until it stops. If the mechanism is working, then at the pressure "A" will open the valve of the exhaust type, which in the switch interval should be sealed.

Reverse valve service is performed using a pressure gauge. If the pressure level drops to 0 bar, it is necessary to disassemble the mechanism and check the integrity of the details.

In order to diagnose the drainage device, the pressure level should be reduced and determine the switching interval "C". If the indicators exceed the norm, it is recommended to twist the screw to the left side, and if the indicators below the norm on the right side. After all the contact nuts are tightened, you need to check the adjusting device setting again.

During the supply of air flow to the conclusions, leakage is 10 cm per minute, and the minimum level of pressure in the system may fall to 1 bar.

Malfunctions and repair

In some cases, it may be necessary to repair, malfunctions can be caused by the leakage of the brake system. The device ceases to remove moisture and condensate in automatic mode. In this case, it may be necessary to replace the sealing ring and springs.

Household air dryer - This is a portable electrical appliance that is designed to reduce and maintain a comfortable relative humidity of air in rooms at home or apartments.

For life, air dryers are usually produced on the principle of cooling air and condensation of water from it using an integrated compressor with an evaporator, as in refrigerators. Therefore, they are called condensation. Such dryers have high performance and are able to quickly create and constantly maintain a comfortable room for humans, pets and property. Relative air humidity within 40-60%.

Device and principle of operation
condensation air dryer

If a cabinet for storing products with a freezer is removed from the refrigerator housing, and everything else is placed in a separate case, then a condensing air dryer will be presented in the photo.

Consider the device and the principle of operation of the air dryer using the example of the German model "Kaut K20", the diagram of which is given in the drawing.

Wet air from the room through the grille on the front panel of the dryer due to the rotation of the fan blades is absorbed into the dryer housing. Further, the air passes through the heat exchanger in which water is removed from it, passes through the filter and returns back to the room is already dry.

The heat exchanger consists of two zones - warm and cold. First, the wet air falls into the heated zone of the heat exchanger and is heated. Next passes through the cold heat exchanger zone and cooled. Since the temperature difference between the heated air and the cold heat exchanger zone is large, then water from the air is deposited on its ribs (condensed) and flows along the walls in the condensate tray.

Electrical circuit and principle of operation

The air dryer to the electrical network of AC 220 V is connected using an electrical plug of type C6. To indicate the supply voltage on the circuit on the front panel, an indicator is installed on the HL1 neon light bulb.

During the operation of the air dryer, water is removed, which is assembled in the catchment reservoir of 5.5 liters. To eliminate the irrigation of the water, the sensor of its level S is set, which, in the case of filling the tank, turns off the dryer and includes an neon light bulb filling the HL2 tank installed on the front panel. Resistors R1 and R2 serve to limit the current flowing through neon light bulbs. The water level sensor is made on a mechanical microswitch.

The required level of air humidity is set and maintained due to the (H) type of TW2001R-A, capable of adjusting relative humidity in the range from 10% to 80%. The gyrostat is controlled by the handle located on the front panel of the dryer. When a relative humidity decreases to a given level, the gyrostat turns off the supply voltage supply to the fan and the compressor.

To ensure air circulation through the heat exchanger serves as a fan M, which has two velocity modes. With a closed switch I, the supply voltage is applied without limitation and the blades of the fan rotate at maximum speed. To reduce the noise level, for example, when working at night, a current-limiting resistor R3 is installed, thanks to which when the switch is blurred, the speed of the blades is reduced. It is worth noting that in this mode, the performance of the desiccant is also reduced.

To eliminate the formation of ice coats on the heat exchanger in the scheme there is a control unit, and the temperature sensor is mounted in the heat exchanger. If the temperature of the cooling section of the heat exchanger is approaching 0 ° C, then the control unit shuts off the compressor for a while until the temperature rises.

How does the compressor work in the dryer?

The compressor is a sealed metal cylindrical body. It has an electric motor with the valve system, which during the operation of the electric motor create high pressure at the output. As refrigerant in compressors, gas is used freon or other with similar physical characteristics, such as R134A.

From the output of the compressor heated and received the liquid state from compressing the freon along the copper tube, first passes through the heat exchanger zone of air heating, where he gives his heat. Going out of the heating zone, the tube is narrowed to an internal diameter of 0.6-0.8 mm, forming a capillary longer than half the meter. Next, the tube is again expanding to the former diameter.

Coming from the capillary tube Freon, is sent to the cooling zone of the heat exchanger. Due to the high difference in the diameters of the tubes there is a pressure drop. As a result, Freon boils and goes into a gaseous state, absorbing a large amount of heat that is selected from the cooling zone of the heat exchanger. After that, Freon returns to the compressor, where gas is shrinking again and sent to the heat exchanger. While the compressor electric motor is included. The circulation of freon through the heat exchanger will occur permanently.

According to this principle, the compressor operates in any home refrigerator, only the heated part of the heat exchanger is installed on the rear wall of its cabinet, and the cooling (freezer) inside it.

Attention! When repairing air dryer and any other electrical appliances included in the household network, caution should be taken. The touch to the bare sections of the circuit connected to the electrical network can lead to electric shock. Do not forget to remove the plug out of the outlet!

Repair air dryer do it yourself

Having studied the principle of operation and the electrical circuit of the air dryer, you can proceed to its independent repair.

First of all, you need to make sure that the water collection tank is not crowded. Next, using a gyrostat handle, set the required level of humidity, for example, by setting a pointer to a number 6 (relative humidity of 60%). The fan speed switch button must be in a recessed position. Then insert the plug of the dryer into the socket, the green display indicator to the HL1 network should turn around and do not burn the red HL2 reservoir overflow indicator. Fan blades should stand and earn a compressor.

If the desiccant is working, then in 5-10 minutes of work from its back grid, cold air must come, and water will appear in the tank. Otherwise, the desiccant is defective and its repair is required.

Finding a fault of any electrical appliance always starts with a socket, fork and a network cord. If the green indicator is glowing, then everything is in order. Otherwise, you need to make sure the sockets, forks and a network cord. To check the socket, it is enough to insert a fork of any electrical appliance into it, for example, a table lamp.

How to disassemble the dryer

If the desiccant does not work and shines the red indicator, and there is no water tank, then the fault is associated with the microswitch S. To check it and repair it is necessary to disassemble the dryer.

In order to get to the details and nodes, you must remove the front and rear panels, and the top cover. Disassembly is more convenient to start from the rear panel. To do this, you must first unscrew the screws that holds the bottom panel.

Then unscrew four more screws, located directly in the hidden holes of the panel and remove it. At the same time it is worth checking the condition of the air filter.

Next, you need to unscrew the four screws in the hidden holes on the front panel and carefully remove it so as not to damage the wires coming from the controls. After that, it will only be left to push the lower edges of the P-shaped lid, and remove it by moving up.

Now all nodes will be available for checking and repair. On the presented photo, inscriptions are applied to the location of all major nodes.

First of all, you need to carefully examine all the detachable connections. They should not be changes in the color of coatings and repactions. Next, check the reliability of landing connectors on the terminals. To do this, you need to try each of the connectors to pull, holding with your fingers, the connectors on the terminals should be kept tightly. In the event that the connector easily starred, then it is necessary to squeeze it with pliers.

Check Indicator and Water Sensor Reservoir

First of all, it is necessary to make sure that the water sensor pusher moves freely. To do this, put pressure on the black key to the black key, which is in the upper right corner of the water tank compartment.

When you press and release, the key should be easily comfortable and return to its original position. At the same time, the characteristic click of the microswitch operation should be distributed. The red indicator when you press the key should go out, and when you release it - light up. If something is wrong, then you need to remove the sensor and find out why it does not work.

The water level sensor is installed on the side of the fan and is the right of its quenching resistance. In order to get to the sensor, it is enough to unscrew a pair of screws and disconnect two halves of the housing in which the microswitch is set. On the photo switch blue.

At the last stage of the check, you need to check with a multimeter or tester included in the resistance measurement mode, the serviceability of the internal contacts of the microspector.

Checking the health of the gyrostat

If the water level sensor and the signal indicator are good, the next element, the control operation of the compressor is the TW2001R-A gyrostat.

The gyrostat is a metal box in which the humidity sensor is placed mechanically associated with electrical contacts. This is a practically programmable switch, closing or disconnecting contacts when the specified humidity level is reached.

To check the gyrostat, it is sufficient to set a low level of humidity using a handle on the control panel and turn on the dryer. If the blades of the fan coated, it means that the gyrostat works fine. If the fan has not earned, it is possible that it is faulty. To check the fan, it is necessary to locate the gyrostat outputs or to supply the supply voltage directly to the fan conclusions, pre-disconnecting them from the drainage scheme.

The air dryer will not work if the water reservoir is not installed (the red indicator will burn). To force the dryer to work without a installed tank, you need to drill the water level sensor key and swap it using, such as a piece of wires, as shown in the photo.

Verification of fan work

When the fan blades are rotated with insufficient speed or stop, the cooling heat exchanger will cool until negative temperature. Then the control unit turns off the compressor, and the dryer will stop working.

The fan can rotate badly due to insufficient lubrication of the engine shaft bearing or windings malfunction. To check the lubricant, it is enough to check the blade with hand. The blades should continue to rotate after exposure. If the blades rotate tight and after exposure do not continue to rotate, then you need to lubricate the bearings through the holes provided for this in its case.

If there is no such possibility, then it will be necessary to disassemble the engine, remove the old frozen lubricant using the White alcohol and apply fresh. If the windings are faulty, the engine will have to replace the new one.

The fan may not work due to a malfunction of the switching button of its mode or a current-limiting resistor (resistance) shown in the photo. When you click on the switching speed of the fan blades, it should be fixed in the pressed state and the speed of rotation of the blades should increase.

If the fan operates when the button is pressed, and the blades are not rotated, the current-limiting resistor is faulty. If the button does not affect the speed, then it is faulty.

How to check the performance of the compressor

If the check showed that the power cord, the water level sensor, the gyrostat and the fan are good, then it remains to check the performance of the control unit and compressor.

From these two nodes, the easiest way to check the compressor, on the label of which it is written that it works from AC voltage 220 V. To check it is enough to submit to its input terminals using a separate cord with a fork network 220 V.

To access the terminals, it is necessary to remove the protective plastic cover from the compressor, for which insert and put pressure in it in it from above the hole of the sting of a flat screwdriver. The latch will go away, and the lid is easy to remove.

Three wires are connected to the compressor. The wire yellow - green Colors is grounding, but by black and blue Wires feed supply voltage. Therefore, you need to remove the connectors from these contacts and submit 220 V. on them if everything is in order with the compressor, then it will work and after a couple of minutes, the cooling zone of the heat exchanger will become cold. In case the compressor engine works, and the temperature of the heat exchanger does not change, it means that freon leakage occurs.

If the compressor is faulty, you will have to contact the service. At home without special equipment, repair the compressor of the homemade master is not forces.

Check and repair control unit

Feeding the supply voltage directly to the compressor showed its serviceability. Only the control unit remained untested and it is obvious that the desiccant does not work because of its malfunction.

The photograph shows the Kaut K20 air dehumidifier control unit. It performs the function of turning off the compressor in the case of the temperature of the cooling zone of the heat exchanger to zero. Thus, the disruption of the dryer's work is excluded due to the formation of a snowy fur coat on the heat exchanger.

For the possibility of maintaining a given temperature of the cooling zone of the heat exchanger between its ribs, the thermistor (thermistribution) is installed, which is highlighted in the photo, in blue. When the temperature changes, the value of its resistance changes. There are two wires from the thermistor, which are connected using the split connection to the control unit.

The photo shows the indication of the multimeter when measuring the resistance of the thermistor at a temperature of 20 ° C. The thermal resistance in the repaired air dryer turned out to be good.

To check the condition of the thermistor, you need to disconnect the connector with the wires from it from the control unit and touched the multimeter knobs to the removed connector contacts measure the resistance value. It should be about 10 com. If the resistance is zero, then there is a closure in the wires. And if equal to infinity, then either the wires in the cliff or faulty thermistor.

Consequently, the control unit itself (BU) is defective. To search for a faulty item it must be removed. First you need to disconnect all connectors with wires from terminals bu. Before disconnecting the connectors, do not forget to photograph or draw the order of their connection.

The control unit is attached to the base using four plastic racks. To release it, you need a tweeze to surpassed the protruding part of the poles, as shown in the photo.

The external inspection of the quality of the paks and the appearance of radio elements did not reveal deviations from the norm. The transversion of the diode multimeter, rectifier bridge and resistance showed their serviceability.

Checking resistors and semiconductor devices installed on the side of printed conductor bu also did not reveal the faulty parts. Only capacitors and a chip remained untested, since it is impossible to check them without falling out.

To further find a fault, it decided to power it from a separate DC source, submitting a "plus" and "minus" conclusions of the rectifying bridge 24 V. The value of the voltage was selected on the basis of the relay supply voltage, which is indicated on its body. Instead of the thermistor, an alternating resistance of 15 com was connected.

Current consumption was about 10 mA, which indicated the absence of a short circuit in the scheme. When the value of the resistance is changed, the relay has triggered, which spoke about the performance by the electrical part of the electric part of the circuit.

It became obvious that in the cliff a current-limiting capacitor with a capacity of 0.68 microf. You see it in the photo.

The refused capacitor was evaporated, and instead of it, a two-time-effective capacity of 0.33 μF is brewed in parallel. With parallel compound of capacitors, the resulting container is equal to the sum of the containers of each of them. The result was the capacity of 0.66 Igf, which is quite enough to replace the intact capacitor.

The control unit without securing was connected to the electrical circuit. When you turn on the air dryer, it earned. It remains only to securely install capacitors on the printed circuit board.

On the printed circuit board, the place to install an additional condenser was absent. Therefore, it was necessary to drop the resistor attached parallel to the condenser and additionally drill two holes in it, in which the second capacitor was installed and the smeared.

The dusted resistor was soldered directly to the conclusions of one of the capacitors. This installation of items guaranteed reliable operation.

Renovated with their own hands the board of the air dryer control unit was installed and fixed on standard racks. Re-checking confirmed the working operation of the air dryer, in ten minutes of operation in the condensate tray, water appeared.

Repair of the network connection indicator

While the first connection of the desiccant, the household network was found that the upper indicator that should shine when the plug is connected to the outlet not shine, although the voltage came to it, since the fan blades rotated.

The indicator was not a collapsible plastic cylinder with two terminals. The indicator on the front panel was mounted using latch.

In order to get to the light source of the indicator, it was necessary to cut it around the circle with the help of hacksaw on the metal and break in the place of propil.

It turned out that inside the neon light bulb included in series with a current-limiting resistor. Checking the resistor showed its serviceability. Consequently, the indicator did not work due to a faulty light bulb.

A good neon glow light bulb with a resistor was removed from the switch from the pilot with the broken key. Such light bulbs are widely used as indicators in many household electrical appliances, for example, in an electric kettle, iron.

A good light was soldered to the outputs of the indicator housing and verified. A broken plastic tube of the indicator was glued into place by glue the moment and additionally plastic was melted with a soldering iron.

After installing the indicator to the place and assembly of the body, the repair of the air dryer was safely finished.

The compressor moisture studio is a kind of filter that allows you to perform the function of using air preparation before it is directly supplied to the system. The need to use this mechanism is caused by the fact that the increased humidity very adversely affects almost any components of the compressor, which can be easily withdrawn.

You can make a filter moisture separator for the compressor with your own hands or just to buy already ready in a specialized store such goods.

Principle of operation of the device

As mentioned earlier, There are many options for the execution of such a mechanism working according to various principles. The classic moisture separator works as follows:

Homemade moisture separator for compressor or purchased?

If a similar question arose, first of all, it is necessary to designate for yourself, which level of cleaning must be achieved. For instance, modern designsSailed in the store allow you to separate unnecessary particles of size up to five microns. There is also a filter, which, when working, is able to stop particles up to one tenth micrometer, however, the price of such a product is definitely extremely high.

In other words, if there is no need to produce extremely thorough cleaning for your compressor, then there is no need to buy expensive filters for this. Moreover, it is best to make a self-made model. Sure, the effectiveness of such a mechanism It will be much smaller than the store, but it will be much cheaper and easier to operate.

No matter, you buy a device or make your own hands, you need take into account the following facts:

How to make a budget model of the device with your own hands?

There is a huge number of ways alone to make a moisture separator For compressor. We will consider the simplest and most popular way that will not allow much effort and materials.

The following materials will be needed:

• cut pipe length of about 0.7 m, as well as a cross section of 100 mm;
• metal sheet whose thickness is 3 mm;
• used fire extinguisher;
• details for fasteners.

After all the necessary materials are prepared, you must perform the following step by step instructions:

If everything was done clearly according to the instructions, a device that contains a falling neck in its top and, of course, the gearbox should be obtained. From the bottom side - connecting nozzleallowing air. Be sure to check the entire design for tightness by connecting to the compressor.

Once all checks are made and no problems are detected, you can connect hoses and everything. You can proceed with the operation of the device.
