Backward Curved Centrifugal Fans +

Backward Curved Centrifugal Fans + are radial fans with blades bent back and equipped with a compact air flow module. They are characterised by extremely high available pressures and a compact design. The aerodynamic air intake cone is integrated into the rotor for maximum efficiency of the fan unit. Combined with energy-efficient, electronically commutated EC motors, they provide very favourable operating parameters: high performance, efficiency, as well as the ability to cope with high flow resistance.

Such a compact design significantly speeds up installing the fan in the device. Thanks to the factory-integrated cone and fan, there is no need to position the entire system. Assembling the unit comes down to screwing in only 4 screws.
