Do-it-yourself construction vacuum cleaner-cyclone. Creating a cyclone for a vacuum cleaner with your own hands: drawings and diagrams Homemade cyclone for a workshop

Cyclone-type plants are used in industry for the purification of gases and liquids. The principle of the filter is based on the physical laws of inertia and gravity. Air (water) is sucked out of the device through the upper part of the filter. A vortex flow is created in the filter. As a result, the contaminated product enters the filter through the nozzle located on the side of the upper part. Since the debris particles are heavier, they settle at the bottom of the filter, and the cleaned product is discharged through the top. It is such a filter, made for the workshop, that we will consider today together with the author of the homemade product.

Tools and materials:
Waste bin 76 l;
Plywood;
Polycarbonate;
plastic pipe;
Coupling;
fasteners;
Masking tape:

Then from the lid, using band saw machine, cut out a circle with a diameter of 40 cm.

The place of the cut is glued, polished.

In a circle with a diameter of 40 cm, which remained from cutting out the bottom cover, cut out the middle according to the diameter of the plastic pipe. This blank will be installed at the top of the device.

For the side wall, the author used transparent polycarbonate. This will allow you to control the operation of the filter and occupancy garbage can. Having rolled up a polycarbonate cylinder, inserted it into the inner hole of the bottom cover. Marked and cut along the joint. I received a cylinder with a diameter of 40 cm and a height of 15 cm.

Inserting a polycarbonate cylinder into the inner ring of the bottom cover, drill holes in 10 cm increments. Fixes the cylinder with self-tapping screws. Whatever crush polycarbonate Bottom part self-tapping screws should be flat.

The top cover is inserted into the other part of the cylinder. Fixes with tape. Having drilled holes, fastens the polycarbonate with self-tapping screws.

For the inlet and outlet, the author used a plastic pipe with a diameter of 7.6 cm, as well as two couplings for it.
First, make an inlet. Cuts off a piece of 23 cm from the pipe. Cuts the coupling in half. Cuts out a rectangle from plywood with sides 12.5 and 15 cm. Cuts a hole 8.9 cm in the middle ( outside diameter couplings). Having inserted a pipe into the hole, it fixes it with a coupling on both sides. Seals the seam with hot glue.

A cut piece measuring 12.5 by 20 cm is screwed to the side wall of the rectangle (12.5 cm).

Then the author cuts the pipe and plywood in such a way that the curvature of the cut coincides with the curvature of the cylinder.

Having attached the structure to the installation site, he makes measurements for the manufacture of a vertical support. Cut it out and attach it to the body. Fastens where the seam of the cylinder goes, thus closing it.

Marks on the polycarbonate the location of the inlet cutout. Cut it out with a drill.

Installs the inlet pipe into the hole, fixes it. The seam is sealed with hot glue.

Next, he makes an outlet pipe. Cuts off a piece of pipe 15 cm. Inserts it into the hole in the top cover. Fits a clutch on both sides. Treated with hot glue.

The author made the lower screen from MDF. Screen size 46 cm in diameter, thickness 3 mm. At a distance of 5 cm from the edge draws a circle. Measures an angle of 120 degrees. Trims the strip between the sides of the corner. Screws the screen to the bottom cover in such a way that the cutout starts immediately after the inlet pipe.

When carrying out repair and construction work, a lot of garbage appears. Sawdust, shavings, scraps of materials mixed with dust should be cleaned regularly. Conventional sweeping with a mop is excluded due to the specifics of the work, if dust and small particles can stick to the surface, for example, after priming or painting.

A conventional vacuum cleaner will not cope with such garbage or will fail very quickly. household electrical devices Designed for medium duty loads.

For such cases, specialized equipment is produced. A construction vacuum cleaner can work for a long time without stopping, has significant power, and it uses completely different filter systems than in household vacuum cleaners.

When to Use a Construction Vacuum Cleaner

Those who are constantly faced with construction, repair and carpentry work are aware of the need for timely cleaning of the workplace at the end of the stage. Cleaning can be carried out repeatedly within one day, so it is quite reasonable to want to make the process easier for yourself.

Styrofoam pieces and polyethylene film , drywall trimmings, chipped plaster, dust after cutting aerated concrete - all this garbage settles not only on horizontal surfaces, but also, having become electrified, is attached to vertical walls.

Cleaning with a mop and dustpan is not always appropriate due to large areas, and washing will only turn dry dirt into wet slurry, especially in unfinished rooms.

Usual household appliance due to the small size of the dust container, it will quickly become clogged, it will have to be constantly cleaned. If large particles hit, there is a high risk of breaking the equipment.

It is under such conditions best solution will use a construction vacuum cleaner.

Pros and cons of a construction vacuum cleaner

High power allows professional equipment to work for a long time without interruption, and a long hose provides access to a remote area without the need to carry a vacuum cleaner or interrupt work.

But it also has disadvantages:

• High price. If you need periodic or one-time work, buying a new expensive tool is not advisable.
• Large size and weight.

Some craftsmen came up with a way out in the form of an additional option to the existing technology. At a fairly low cost, you can assemble a cyclone filter for a vacuum cleaner with your own hands. This design will increase the capabilities of an existing conventional household vacuum cleaner.

Making a cyclone with your own hands

The Internet has huge selection instructions for self-manufacturing filter cyclone, including the attached drawings and photographs. But they are united by a standard set of components.

So what we need:

Assembly instructions.

The main indicator that a do-it-yourself cyclone for a vacuum cleaner is assembled correctly will be debris that collects at the bottom or settles on the walls of the container, while suction will be fast and of high quality. Do not forget to control the tightness of the structure.

The history of the appearance of the cyclone filter

Technology Creator cyclone filter is James Dyson. It was he who first made a filter with a work based on the action of centrifugal force. Why did this device become so popular and in demand that the inventor filed a patent for it?

The filter consists of two chambers. Under the action of centrifugal force inside the unit, the debris begins to twist into a funnel. Large trash at the same time, it settles in the first chamber, the outer one, and dust and light debris are collected on the inside. So clean air comes out through the top hole.

The main advantages of the cyclone filter:

• dust bags and their constant replacement are not required;
• compact filter dimensions;
• quiet work;
• easy-to-remove lid allows you to regularly check the level of contamination and dispose of garbage in a timely manner;
• speed and efficiency.

A vacuum cleaner with a cyclone filter can be used both in everyday life and for professional purposes.

If a person has his own workshop, then one of the most important issues is cleaning the premises. But unlike cleaning the dust in the apartment, the usual household vacuum cleaner it will not help here, since it is not designed for construction waste and sawdust - its garbage tank (dust collector or bag) will clog very quickly and become unusable. Therefore, a home-made cyclone filter is often used, which, together with a household vacuum cleaner, will help clean the workshop.

Introduction

Wood dust and other technical debris, although it seems harmless at first glance, in fact, they are fraught with many different dangers, both for the master and for the equipment. For example, prolonged work without protective equipment that prevents dust from entering the respiratory system can cause serious complications with the respiratory tract, worsen the sense of smell, etc. In addition, tools that are in the workshop under the influence of dust can quickly fail. This happens because:

1. dust, mixed with the lubricant inside the tool, forms a mixture that is completely unsuitable for lubricating moving parts, resulting in overheating and further breakage
2. dust can impede the rotation of the moving parts of the tool, which leads to additional loads, overheating and failure,
3. dust clogs the air ducts designed to ventilate the heated parts of the tool and remove heat from them, as a result of overheating, deformation and failure again.

Thus, the issue of the quality of removal of sawing products and, in general, cleaning of the premises is very acute. Modern power tools are equipped with systems for removing dust and chips directly from the sawing area, which does not allow dust to spread throughout the workshop. In any case, a vacuum cleaner (or chip blower) is needed for the dust removal process!

There are good industrial vacuum cleaners and if possible, it is better to choose the most best option for price and quality and buy construction vacuum cleaner.

However, there are times when you already have a household vacuum cleaner and it is easier to upgrade it and solve the collection problem. construction debris in room. To do this, you need to use a cyclone filter - it is done in half an hour with all the necessary elements.

Principle of operation

There are a great many different designs of cyclones, but all of them are united by the same principle of operation. All designs of cyclone chip blowers consist of three main parts:

• household vacuum cleaner
• Cyclone filter
• Waste container

Its design is such that the flow of intake air is directed in a circle and its rotational movement is obtained. Accordingly, the construction waste contained in this air stream (these are large and heavy fractions) is affected by centrifugal force, which presses it against the walls of the cyclone chamber and, under the action of gravity, it gradually settles in the tank.

The disadvantage of a cyclone vacuum cleaner is that only dry garbage can be collected in this way, but if there is water in the garbage, then there will be problems when sucking such a substance.

The vacuum cleaner must be powerful enough, since in its normal operation it is supposed to suck air through a standard hose. In the case of using an additional cyclone filter, an additional filter appears in the air path, and the total length of the duct is more than doubled due to the additional duct. Since the design turns out to be as maneuverable as a separate vacuum cleaner, the length of the last hose must be sufficient for comfortable work.

Preparatory work

As mentioned above, you can make a cyclone filter for a workshop in half an hour, but for this you need to check the availability of everything necessary for the production of a chip blower with your own hands, namely: tools, materials and consumables.

Tools

Making a cyclone filter

Creating a homemade chip blower consists of a number of steps:

1. Creating a retaining ring and curly insert
2. Retaining ring installation
3. Installing the side pipe
4. Setting the top entry
5. Curly insert installation
6. Assembling the cyclone filter

Creating a retaining ring and curly insert

It is necessary to cut off the side of the small bucket, which is used to attach the lid. As a result, you should get such a cylinder (well, a little on a cone).

We make the markup - put a small bucket on and draw a line along the edge - we get a circle.

Then we determine the center of this circle (see the school geometry course) and mark out another circle, the radius of which is 30 mm larger than the existing one. Then we mark the ring and curly insert, as it shown on the picture.

Retaining ring installation

We fix the ring on the edge of the small bucket so that we get a rim. Fastening is done with self-tapping screws. It is advisable to pre-drill the holes so as not to split.

We mark the roof of a large bucket. For marking, you need to put the bucket itself on the lid of a large bucket and circle its outline. Marking is best done with a felt-tip pen, as the trace is clearly visible.

It is important to note that all connections must be airtight, respectively, before installing the cover, the connection must be smeared with sealant. You also need to smear the junction of the wooden ring and the small bucket.

Installing the side pipe

The side pipe is made from a sewer outlet of 30 degrees (or 45 degrees). To install it, you need to drill a hole in the top of the small bucket with a crown. Note that the bottom of the small bucket is now the top.

Setting the top entry

To make the top entry, you need to drill a hole in the upper part of the chip cutter (small bucket), that is, in the center of the former bottom.

To securely fix the inlet pipe, use additional element strength in the form of a square blank of 20 mm thickness with a central hole for a 50 mm branch pipe.

This workpiece is fastened from below with four self-tapping screws. Before installation, for tightness, the joint must be smeared with sealant.

Curly insert installation

Curly insert - very important component homemade chip blower, it must be fixed inside the cyclone filter, as shown in the photo.

Assembling the cyclone filter

Then you need to connect the air ducts correctly:

1. Upper nozzle - to a household vacuum cleaner
2. Angled elbow entering from the side at an angle - to the hose.

Homemade cyclone vacuum cleaner(chip blower) is ready.

No matter how extensive the range of vacuum cleaners on the market is, not everyone can afford to provide themselves with the appropriate units for industrial and domestic needs. The reason for this is often the high cost of industrial vacuum cleaners. On the one hand, cleaning in a garage or workshop takes a lot of time, and on the other hand, a vacuum cleaner costing from $ 500 to $ 1000 with a large dust container and good suction performance. An excellent solution to the problem can be a homemade vacuum cleaner for the workshop, made by yourself. It is enough to remember how well we know how to make something. The same principles can be applied when a factory-made home assistant fails in terms of breaking the integrity of filters or dust collectors. To implement such a project, you will need to be patient and have some improvised means that may be gathering dust in the far corner of the garage. A homemade vacuum cleaner is easily suitable for indoor cleaning, helps to collect construction debris, and allows you to remove dust flying out from under working surface power tool.

Homemade vacuum cleaner filter

Initially, before you start stocking up on materials for the manufacture of the unit, you should clearly define the tasks that the vacuum cleaner must solve. So, a garbage collection container can be a couple of liters for cleaning in an apartment and other domestic premises, or several tens of liters for cleaning construction waste at work sites or in garages. For such a container, a large barrel or a small bucket from under any building material is perfect, the main thing is that you have the opportunity to ensure the sealing of this container during the garbage collection process. If the required degree of tightness is not achieved, fine dust fractions sucked in by the air flow through the holes will enter the air of the home or air working area. The situation is much worse when cleaning harmful chemicals and building materials, since in the form of dust or aerosol in the air of the working area, they can worsen well-being and harm human health.

Apart from air pollution, poor sealing will result in loss of suction power. If instead of a garbage container, you decide to make a homemade bag for a vacuum cleaner, it should also hold dust and not let it into the environment.

The size of the cells between the fibers should be such that the dust certain sizes contained inside the bag and not blown back into the room. Of course, in domestic premises the type of dust and its dimensions are larger than the dust of construction waste and dust flying out from under a working power tool.

How to choose a pump?

The device for creating an air flow can be taken from a ready-made vacuum cleaner that was in use, but for one reason or another unsuitable for further use, or you can use any pumping device that meets the requirements:

• Should work in the rated load mode for a long time, sufficient to complete the tasks and all manipulations;
• Must be able to withstand both short-term and long-term overload so that a clogged hose does not cause overheating and failure.
• It must provide sufficient suction power, taking into account the installed filters and other obstacles in the path of the air flow.

In areas where it is not required high strength suction, the role of a pump can be performed by an ordinary household vacuum cleaner, for example with a bagged dust collector. To do this, the bag dust collector is removed, and the necessary components are attached to it.

Making a filter

The optimal solution for creating a filter device for homemade vacuum cleaner will become a cyclonic filter made by hand. The manufacturing principle is quite simple: you will need to make a structure from a cylinder with two holes for the inlet and outlet of the air flow sucked in by the vacuum cleaner and a truncated cone pointing down. For these purposes, any material from metal to plastic can be suitable. The only requirement for the entire design of the cyclone is high-quality sealing of all slots and openings. The reason is the same as for the dust collector: the appearance of a dusty fraction in the air and a decrease in the performance of the unit. Consider the option of making a homemade cyclone for a vacuum cleaner from plastic pipes. The only difficulty in manufacturing will be the conical part, which will have to be selected from finished parts or made independently. To make you will need:

1. a pipe with a width of 100 mm and higher, the larger the pipe, the better the work of the cyclone filter can be obtained;
2. two small diameter pipes for inlet and outlet. On average, pipes from 50 mm and below are taken, depending on the diameter of the working hose.
3. a conical part, the larger diameter of which corresponds to the diameter of a large pipe (cylinder).
4. For wide cylinders, from 150 mm in diameter and more, a small diameter cord or flexible tube will be required for the filter guide.
5. A cap that will fit snugly into the top bore of the cylinder.
6. glue or material for soldering, sealant.

Homemade cyclone a new vacuum cleaner will turn out in this way much cheaper than a factory one due to a cheap filter, the cost of which will cost 8 - 10 dollars, unlike the original factory cyclone filter. Initially, a wide pipe is taken, selected for the role of a cylinder, and cut to the required height (if you did not manage to purchase right size). The holes for the inlet and outlet should be cut as accurately as possible, avoiding chips and uneven edges. If the air intake hole should be placed in a horizontal plane, then the air outlet hole can be located both on the pipe itself and on the top cover of the cyclone filter. It is worth proceeding from where it is most convenient to provide high-quality sealing. If the material of the cover is much easier to cut and the sealant is fixed normally, then it is better to give preference to the cover, otherwise, the outlet should be placed on the body. The main condition is that the outlet pipe must be located above the inlet. This will allow the debris to sink down, passing only air and fine dust to the outlet. To capture such dust, you can use some homemade filters, for example, fabric or adapt a car filter, this will protect a home-made construction vacuum cleaner from types of debris that are dangerous for the engine.

To create a swirl of the air flow, which is sucked into the cyclone, stick on the surface of the cylinder in a spiral flexible hose or cord made of waterproof material. Such a spiral will increase the efficiency of the cyclone filter. It should be noted that such an addition will only work for the pipe large diameter into which you can easily penetrate with your hands. Input and outlet pipe is fixed in the corresponding holes with sealant, heat shrink, adhesives or pieces of pipe, which are soldered with a soldering iron. The main task of this material is to firmly fix and seal the tubes. The top cover should fit snugly against the edges of the cylinder, you can, if desired, fix it with a sealant, but then the process of cleaning the internal surfaces of the cyclone filter from accumulated debris will become more complicated. We should also not forget that the surface can become electrified and accumulate a static charge that will hold dust. Therefore, it is better to immediately install the cover on the door seal, this will prevent dust from entering the room and will allow you to freely open the cover at the right time. The conical part can be strengthened with sealant or glue, since it is unlikely to have to be removed. Through the hole in the truncated cone, the debris will fall into the bin.

Such a device can be useful not only for those who are thinking about how to make a homemade vacuum cleaner, but also for owners of working factory-made vacuum cleaners. If you are tired of constantly changing the dust bag or the filters are clogged, then installing a homemade cyclone will help solve this problem without the extra cost of purchasing a new vacuum cleaner.

If you undertook to make an industrial vacuum cleaner, then you can mount a socket on it for connecting a power tool, which will allow you to ensure parallel operation of the vacuum cleaner and the tool. An automatic activation system for the vacuum cleaner can be connected to the socket circuit, which will suck up dust when the tool is started. In addition, such a system can provide a delay in turning off the vacuum cleaner after opening the power tool circuit. This will allow the industrial vacuum cleaner to collect the debris and dust that have flown out within a few seconds after turning off the power tool.

What should be considered when making a homemade vacuum cleaner?

In the manufacture of home-made vacuum cleaners, some craftsmen, in order to save their own time and effort, include factory parts and spare parts in the unit. In most cases, such a step is quite justified, with the exception of the installation of filters. For a homemade vacuum cleaner, you should by all means avoid installing the notorious HEPA filters. These filters work on the principle of retaining fine dust particles in the pores of the filter itself. Because of this, as the filter fills with debris, suction power and, consequently, the quality of cleaning will gradually be lost. All kinds of attempts to clean such filters do not lead to the expected results, since the dust is not completely blown out, and when washed and washed out, it leads to the processes of decay and the development of bacteria. It is clear that these bacteria are blown back into the room during operation, this process is expressed in bad smell while the vacuum cleaner is running.

To optimize the operation of the vacuum cleaner, you can connect two hoses - one for suction, the other for blowing, the blowing hose will allow you to effectively clean various surfaces and hard-to-reach places, because the immediately blown dust will be collected by the suction hose. However, the absence of a filter in conventional vacuum cleaner can also lead to the opposite effect, because in order not to use it, it is necessary to provide the device with an ideal cleaning system, and it is oh so difficult to do it at home. So if you need real cleanliness, it’s better to save on something else, and choose a reliable and filterless cleaner to clean both air and surfaces. And all this about the separator apparatus! So good luck with choosing and using a vacuum cleaner.

Owners of small workshops and just home craftsmen often have to deal with the problem of air purification after intensive work on woodworking, grinding metal surfaces etc. Conventional ventilation of the room will not help here, you will need to install specialized equipment. With known skills, you can do it yourself.

Purpose and characteristics of cyclones

The cyclone is a specialized air cleaning unit (although similar units are also used as chip extractors, sawdust and other waste disposal agents).

As air purifiers, industrial designs of cyclones should provide suction and dust removal with an efficiency of at least 85 ... 90%, with dust removal of fragments with a size of at least 10 ... 12 microns. They are equipped various designs filters. The most effective are electrostatic precipitators, which simultaneously remove static electricity from dust particles.

The principle of operation of the cyclone is as follows. Air enters the volute-shaped inlet space of the cyclone at a high speed (up to 20 m/s), for which fans are usually used. The air containing dust particles is swirled, after which it enters the conical cavity of the apparatus. Features of the geometric structure of the cyclone cause a gradual increase in the speed of the air flow containing dust and other waste. In the process of this, the heavier dust particles separate from the lighter ones. The former settle to the bottom, while the latter, moving in a cone-shaped space, fall into the dust collector, from where they can be easily removed using a bucket or a sealed container. Purified air is removed to the atmosphere through a pipe.

The number of cyclones, depending on the requirements for the quality of dust removal, can be made different: there are groups of three, four and even eight single cyclones.

The operational requirements for cyclones include the following parameters:

1. allowable dispersion of particles that enter the cyclone, microns.
2. process efficiency, which is expressed in the maximum weight concentration of particles after dust removal, in g/mm 3 ;
3. cyclone performance, m 3 /h;
4. boundary temperature of air or gas entering the cyclone mouth (more typical for gas cleaning systems than dust removal systems) - usually up to 400 ... 600 ° C;
5. internal diameter of the cyclone, mm.

In addition to purely constructive requirements, there are also conditions for the high-quality installation of air cleaning devices. For example, when the gaps in the air duct connections are exceeded, air leakage often occurs, in which the performance of separating dust from air is sharply reduced. The allowable value of suction should not be more than 6 ... 8%.

Cyclones not only remove dust from the surrounding air, but can also supply clean air into the room.

Household cyclone design

There are no universal cyclones for various cleaning operations. For example, a chip blower should have increased pipe wall strength to prevent premature wear. With regard to a cyclone designed to collect and remove sawdust, it is important to provide for minimal losses in the suction ducts. Providing a cyclone for the purpose of air purification from cement dust arising from construction work, special attention is paid to the design of filters.

In domestic conditions, cyclones are considered the most versatile, purifying the air from coarse dust. By changing the design of the filters, such devices can be made for dust removal purposes, as a chip extractor, for cleaning the air from sawdust in a woodworking workshop (for example, at an existing sawmill).

The components of this unit are:

• body - includes a conical and cylindrical parts, and the shape of the conical part has a predominant effect on the quality of the process;
• branch pipe - one or more, where the source polluted air enters;
• exhaust pipe designed to remove dust-free air;
• inlet filter (or their system) as a chip extractor;
• receiving bucket;
• drive motor;
• fan.

All of the listed parts / assemblies can be purchased or made by hand.

Motor selection

Since a home-made cyclone is installed in the workshop, the main parameter of the engine is its power and the number of revolutions of the rotor. In the presence of a fan, the engine power does not matter much, since dust particles are still in a working machine, sawmill, etc. will not hit. However, the power and diameter of the volute of the cyclone must be interconnected. With a snail wheel diameter of up to 300 ... 350 mm, a high-speed (required!) Engine up to 1.5 kW is quite suitable. With smaller diameters, the power may be lower, but the cleaning performance will also decrease. Therefore, if there is a metalworking machine in the workshop, an engine from 1 kW is accepted.

The power of the electric motor increases significantly if you plan to equip it yourself homemade device outside the premises. Free space will increase, but the cleaning efficiency will decrease, mainly due to losses in the ducts. It is also worth noting that in the cold season, such a home-made cyclone will effectively “pull” heat from the workshop.

A good option should be to recognize the purchase of an electric motor complete with a receiving snail, the number of which determines the consumer capabilities of a home-made air purification system. The most common parameters of snails for domestic use and recommended electric motors for them are shown in the table:

The systems are supplied with rubber vibration isolators. They are able to create a working pressure of 0.8 kPa and above.

When choosing (or making with your own hands) a snail, preference must be given to a radial air intake pattern than a tangential one.

In the latter case, unproductive losses increase for a self-made snail, and the inertia of the particle selection method for the variant with a chip ejector will be very low.

When choosing an engine, it must be taken into account that the air velocity in the device cannot be less than 2.5 ... 3 m / s. With unsatisfactory cleaning, the elements of a home-made cyclone as a chip extractor (filter, bucket) are quickly clogged with chips, sawdust and other small waste.

Manufacturing of cyclone elements

On specialized Internet forums, you can find drawings of all the components of the unit that are available in order to make them yourself. From improvised means, an alteration of a household (or better, an industrial) vacuum cleaner is often made. Additionally required:

• a set of hoses made of translucent corrugated material (this will facilitate visual control of dust particles that have settled inside). For a chip blower, rubber hoses are more practical;
• a soundproof box that will perform two functions - it will provide a reduction in the noise level in the workshop, and additional protection of all machines and power tools located there from static electricity periodically accumulated by dust. To this end, the box can be made with your own hands from plywood, and from the inside you can finish it with any type of sound insulator;
• air ducts for purified air: they are assembled with their own hands from a thin aluminum sheet, and are interconnected by folds;
• waste collection container - can be made from a conventional construction bucket with a capacity of 20 liters or more, which is sealed with a corrugated hose with the body of a home-made cyclone;
• a filter (a filter from trucks can be used), which is installed on the outlet pipe.

A vacuum cleaner converted with their own hands for the needs of dust removal is checked: first on Idling, driving ordinary air through the system, and then with the connection of the vacuum cleaner to a running machine.
