Axial roof fans consist of a new design impeller, an all-welded casing made of rolled sheet and an asynchronous motor located in the casing, a hood and a base plate. Thanks to its special aerodynamic shape, the motor support stand serves as a guide apparatus.

The impeller is made with variable-incidence blades, the setting angle of the blade is adjustable for maximum effi ciency. The volumetric blades are made by using injection molding. The air fl ow cross-section is maximized, which gives a signifi cant reduction in the outlet speed.

Design:

• general purpose industrial (N); 
• corrosion-resistant (CR1); 
• explosion-proof (V); 
• corrosion-resistant, explosion-proof (VCR1).
