Industrial fans differ from household fans in higher performance and are used in factories, factories, catering kitchens, mines, workshops and other places to supply fresh air or remove harmful gases and fumes. Thanks to their work, the vital activity of people underground, in a confined space is possible, and the likelihood of an explosion of dangerous gases is also eliminated. Our experts will tell you how to choose an industrial fan, and a review of the best models will show which products are already successfully used in Russia.
How to choose an industrial fan
First, we note the main criteria for choosing industrial equipment:
- Air exchange. It happens from 2000 to 36000 m³ / h and above. It is calculated based on the area of \u200b\u200bthe room and the number of people constantly staying in it. The minimum norm for a person is 30 m³ / h, but usually this value is taken with a margin of 60-100 m³ / h. If the air exchange does not meet the needs of the workshop, then carbon dioxide and other life-threatening substances will begin to accumulate in the room.
- Power. Industrial units have from 450 to 7000 watts. The higher the indicator, the stronger and easier the fan will be able to spin the blades, as well as work without overheating.
- Tightness class. Models rated IP55 and above can be placed in areas exposed to rain without protective covers. Other devices need to be equipped with canopies or a full roof.
- Operating temperature. It can be from -20 to +70 degrees. But each fan has its own range, which affects the installation location and period of operation.
- Carried medium temperature. In addition to the ambient temperature, which affects the engine, the temperature of the carried gases, which affects the impeller, is also taken into account. Some models are suitable only for supplying fresh air and pumping out carbon dioxide. Others are suitable for use in hot shops, bakeries and welding stations.
Rating of the best industrial fans
The best radial (centrifugal) industrial fans
Industrial centrifugal fans have a housing in the form of a large “snail”. Inside there is a round-type turbine with blades located across. They are placed at a slight angle to capture air. The device can work both for suction and for supply. These types of fans are installed on the floor, and rectangular or round channels are laid from them, stretching through the tunnels and rooms of the building. Thanks to one such model, several rooms can be ventilated at once.
The industrial unit is connected to a three-phase 380 V network and is suitable for single-sided supply of fresh air to production workshops, commercial premises and administrative buildings. The model joins the highway with a diameter of 250 mm. The body materials are rust-resistant, so the machine can be placed in an unheated room with high humidity. Experts note the low noise level of the fan, which is important if people are working nearby or the unit is located in an adjacent room with administrative buildings. The industrial cooler is able to function for a long time without interruption, therefore it is suitable for industries operating in several shifts.
Against the background of other centrifugal fans, this industrial model stands out due to its small installation depth. This form factor makes it easier to place in tight spaces, such as near an exit in an industrial factory.
- materials are resistant to corrosion;
- low noise level;
- able to work for a long time without overloads;
- resistant to aggressive environments;
- compact body.

This makes it ideal for catering kitchens, bakeries, candy factories, cafes, restaurants and other establishments with hot steam and gases. The manufacturer also allows the use of a fan for welding booths to remove the products of combustion / melting of electrodes, wire and flux. Experts in the reviews note curved galvanized steel turbine blades with a long service life.
The feature of an industrial ventilated installation is the presence of an EC motor. Unlike AC motors, it uses intelligent technology to control the speed. Speed control is carried out with each signal from 0 to 10 V, which is quite sensitive. As a result, the motor operates at optimum load, efficiency losses are reduced and power consumption is reduced.
