Industrial-grade fans are distinguished by power and performance increased several times as compared with household products. Accordingly, the overall dimensions, mass and noise level increase. They are used for air exchange of industrial buildings, sports facilities, for general civil purposes. Ventilated catering, grain hangars. They are equipped, as a rule, with an asynchronous electric motor powered by a three-phase network. According to the principle of action and purpose are divided into axial, centrifugal (radial, through passage), channel. Selection parameters: power, performance, speed, outlet pressure, efficiency.

AIR SC YWF4E-500B - axial invoice
General purpose axial type fan. They are used for air exchange in rooms with non-aggressive environment. The small content of dust particles is allowed. Used outdoors and indoors. Made in waterproof and dustproof design.
An electronic engine speed adjustment mechanism is installed in the range of 0 ~ 100% of the nominal. Stainless steel was used for the blades. Rolling ball bearings are used. The engine and rotor have been pre-dynamically balanced.
Pros:
- Simple design, convenient and clear installation, electrical connection.
- Wide range of adjustment of speed.
- Steel for main components, protective grille included.
Minuses:
- Only for industry, noisy.
WOKS 200 - for general use
Axial radiator for operation in areas with the need for constant air exchange: sports halls, household hangars, storage rooms, industrial halls and other similar structures. Equipped with double-sided protective grille.
Single-phase asynchronous electric motor 220 volts. The main components, including the grilles, are made of steel sheet material. Used weatherproof coating based on powder enamel. An electronic speed controller is provided.
Pros:
- High-quality assembly, reliable protective coating.
- The average noise level among analogs.
- Reliability, durability, long lifespan.
Minuses:
- Not marked.
WD630-CH-03-08 - German quality
Consignment kit for ventilation of industrial, general, sport premises. Characteristic differences - manufacturing according to high international quality standards.
Electric motor from Ebmpapst (Germany), asynchronous three-phase 380 volts. Heavy duty blades are made of lightweight and durable aluminum alloy. Thermal protection was mounted, - thermal switches (fuse) with the possibility of automatic restart.
Pros:
- Very high quality manufacturing, fitting all knots, does not rattle, does not creak.
- Well balanced unit.
- Fully performs all declared functions.
Minuses:
- Negative properties are not marked.
CMB / 4-200 / 80-0.25 - without support frame
Centrifugal fan type with snail housing. The impeller is mounted on a single motor shaft. The latter is mounted directly on a common prefabricated building. Further, the connection with the ventilation system through the flanges.
The rotor is made of high quality galvanized steel. The impeller is bent forward, which provides a reduction in size and efficiency of work. Applied protective anti-corrosion epoxy coating. Power - single-phase network 220 volts.
Pros:
- Easy, productive, uniform design.
- Reliable protective coating based on epoxy compounds.
- A very simple connection of all nodes into one.
Minuses:
- Consumers of negative properties do not mark.
CM 21.2H - heat resistant
Professional series fan through passage. The principle of operation is centrifugal (radial). A distinctive feature of the design is work with an air-gas mixture of elevated temperature.
It is operated as part of the air vent from solid fuel heating boilers, refrigeration units, chemical laboratories, paint booths and other similar premises. Galvanized sheet steel was used for manufacturing. The product is made in moisture-and dust-proof design.
Pros:
- Work at elevated temperatures in a similar thermal environment.
- Possibility of operation paired with a solid fuel boiler.
- Unpretentious, easy to handle, maintain.
Minuses:
- Noisy, requires remote installation or noise isolation.
CMPT / 2-200 - operation in aggressive environments
Prefabricated structure for operation in aggressive environments: removal of gases, smoky products of combustion, chemical or other fumes. It consists of a 220 volt asynchronous single-phase electric motor, a polypropylene impeller and a casing made of high-quality polymer.
Rotating parts have passed the stage of dynamic balancing to reduce vibration phenomena. There is a hole for the drain formed in the process of ventilation, condensate.
Pros:
- High-quality anti-corrosion plastic, exploitation in smoke.
- Virtually no vibration.
- Performance, reliability, unpretentiousness.
Minuses:
- Negative traits are not marked.
CMFD 400 - Axial Channel
Industrial fan channel type. Designed for use in the composition of the ventilation ducts or shafts. The principle of operation is axial. Equipped with an effective diagonal impeller with stationary guide vanes.
Dynamic balancing and high-quality assembly provide high efficiency. For manufacturing applied high-quality durable aluminum alloy. It is possible to connect the speed control system. Food - the three-phase power supply network of 380 volts.
Pros:
- Productive, powerful, high energy efficiency (efficiency).
- Aluminum moisture resistant stainless steel case.
- Reliability, easy to maintain.
Minuses:
- Disadvantages consumers do not note.
VSV 311-4 L1 - roof fan
The fan of the vertical discharge of air pumped out of the building. Refers to the roof type. The advantage of the form - saving space, reducing the path made by air (reducing aerodynamic drag).
It is completed with an asynchronous motor made in Germany. The blades are bent back - the ability to save electricity and resistance to peak loads. The principle of the fan - centrifugal (radial). Used high quality galvanized steel.
Pros:
- Highly efficient, performance, build quality.
- Moisture and dustproof design, galvanized steel.
- High reliability, long lifespan.
Minuses:
- Only positive moments.
