Nussun centrifugal fans, Less noise, higher performance


Nussun centrifugal fans are available with forward and backward-curved blades. The quiet-running centrifugal fans with forward-curved blades are also supplied with a scroll housing. The centrifugal fans with backward-curved blades are designed as freewheel fans and do not require a scroll housing. In the case of centrifugal fans with external rotor motors, the motor is positioned in the impeller, ensuring not just optimum cooling of the motor, but also a particularly compact design. The entire range is available with both AC and EC technology. In addition to being particularly energy-saving, the integrated electronics also make it possible to implement any control, monitoring and maintenance functions – for both the smart home and Industry.
