Commercial fans based on axial motors are designed for ventilating large utility rooms, commercial spaces, garages, small food service areas, etc., where a higher air exchange rate is required—even exceeding 1,000 m³/h. They can be installed in ventilation ducts or directly in walls as exhaust fans. Thanks to the use of 3-speed motors, the fan’s parameters can be adjusted to the user’s needs, depending on the connection method. Commercial fans meet IP42 safety class, protecting them against foreign solid objects with a diameter of 1 mm or larger and against falling water droplets when the housing is tilted at any angle up to 15° from the vertical in either direction. Depending on the model, they are available in 5 sizes: ø 200, ø 210, ø 250, ø 315, and ø 320.
