It is the wheels that serve as the basis reliable work the fan mechanism throughout the entire period of its operation. All calculations of impellers using the finite element method are fully consistent with the experimental data;
• when choosing motors, the manufacturer optimized the power reserves, which, in the final version, allows the use of designs with low installed power, which is especially important for fans of small numbers;
• the use of fans of all numbers is provided, which are made according to the first structural scheme. Each of them contains frequency converters, which allows you to accurately adjust the operating mode of the device during commissioning tests, as well as during further operation of the fan. A technique for choosing a motor according to optimal sizes, which is able to work with a frequency converter and change the frequency range of the current used;
• high aerodynamic performance of serial products is ensured by a simple design of the wheel, as well as a seal that is located between the wheel and the nozzle when using high-quality assembly technology in the design;
• the shape of the spiral casing was slightly changed, due to which the average speed of the air flow is reduced in the outlet section of the device, while the pressure loss in the adjoining ventilation network is also reduced.

The main purpose of VRAN fans

The fans can be installed in standard ventilation systems, as well as in air conditioning and air heating systems in industrial buildings or in residential premises. To prevent the fan from damaging the fan during movement for two hours, the air-gas mixtures, the temperature of which is in the range of 400-600 ° C, are made using special versions of the VRAN®-DU type.

Fans are of the following types:

• general industrial, which the manufacturer, as a rule, marks with the "H" sign;
• heat-resistant, which are marked as "F";
• anti-corrosion (K1), which can prevent the formation of corrosion and rust;
• corrosion-heat resistant (К1Ж) - such fans combine two types of mechanisms and their properties;
• explosion-proof (type "B" marking) - products are made according to only the first structural diagram;
• heat-resistant, the mechanism of which has explosion protection (VZH) - execution is similar to the previous type of fans;
• fans that have a protective mechanism against explosion and corrosion (VK1; VK3);
• explosion-proof corrosion-heat resistant (VK1ZH);
• fans resistant to seismic activity, which can be easily combined with other types of designs listed above.

  Internal fan mechanism

  In its design, each fan has an impeller that rotates both clockwise and counterclockwise. The wheel blades are specially shaped and bent slightly backward. The volute casing of the device is also rotatable. Fan mechanisms are manufactured both according to the first and fifth constructive schemes in accordance with the accepted standards of GOST 5976.

Fans made according to the first design diagram are directly connected to the motor and are of two modifications, such as VRAN6 and VRAN9. They differ in the number of blades of their impeller.

The fans, which belong to the fifth design scheme, contain a belt drive in their design. Such products are available in only one modification VRAN9. In contrast, VRAN9, which belongs to the first design scheme, is equipped with motors, thanks to which it is possible to adjust the speed of rotation.
For devices climatic performance types U1, UHL1, T1, the mechanism design provides additional protection against atmospheric precipitation, which is supplied to the drive and the exhaust part of the fan.

Fans used in large industrial enterprises, have a noise-insulating casing, which makes it possible to significantly reduce the noise level of the device operation to a value of 12 dB. In this case, the overall sound pressure level decreases by 25-30 dB at a distance of 5 meters.

Upon request, the customer can purchase additional components in the form of vibration isolators and flexible inserts, which reduce the level of dynamic loads. It will not be superfluous to get: flanges reverse action, frequency converters, as well as various devices that allow you to perform smooth start fan.

Operating conditions
According to the operating rules and regulations, in order for the fans to be able to serve their owner for many years, they must be installed outside the area in which people are constantly staying.

Products according to the standards of GOST 15150 are able to withstand a variety of climatic conditions of work, ranging from moderate to tropical climates.

Basic operating conditions:

the temperature around the device must correspond to:
- "-" 45 - "+" 40 degrees Celsius for a temperate type of climate;
- "-" 60 - "+" 40 degrees - for a moderately cold climate;
- "-" 10 - "+" 50 degrees - for the tropics.
In this case, the average value of the so-called vibration velocity of all external mechanisms that serve as a source of vibration vibrations should be within 2 mm / s.
