WB is a new line of centrifugal fans for clean air. The fans of the WB series are characterized by quiet operation, light construction and high efficiency at relatively high pressure, thanks to which they can be used both for comfort ventilation and for local exhausts. The fans of this series are used, among others, in exhaust ventilation systems of such facilities as kindergartens, schools, shops, churches, folk houses; changing rooms, smoking rooms, etc.
WB fans are also commonly used as blowers for various types of tanks and rooms, e.g. for aeration of sewage chambers, blowing for industrial boilers, etc.
The fans use a radial impeller with forward-curved blades, which is characterized by quiet operation and small dimensions in relation to centrifugal fans with backward-curved blades. Coil-shaped fan housing with flange ends. Air inlet – round flanges, air outlet – rectangular flange. The fan has a detachable mounting base (can be mounted in any position).
The ventilators used integrated motor – the fan turbine has been integrated with the impeller of the drive motor. Thanks to this solution, the fan has a compact design and has much better cooling than in the case of fans with an external motor. Models: 200; 250; 300A; 300B available in 230V version with easy adjustment by external voltage regulators. The WB-350 model is adapted to adjust the speed with an inverter.
