The VK centrifugal fan is a duct fan for circular duct system. Provides supply and exhaust ventilation with a low level of fan noise. Efficiency up to 1080 m ³ / h. The fan is used in ventilation of individual rooms, buildings in collective housing and public utilities. It is used in exhaust ventilation of toilets, kitchens and other rooms with high humidity. Adapted for installation at any angle relative to the fan axis.

Building

The fan and impeller housing is made of ABS plastic. The fan has a hermetic connection box. Single-phase motors with an external rotor were used, with blades bent backwards. A protection against overheating with automatic restart has been built in. The engine uses ball bearings.

Speed control

Speed regulation can be done smoothly (thyristor regulator), as well as stepped (transformer regulator). Fans can be connected by a pair of units to one controller, provided that the available power and working current will not exceed the nominal parameter in the controller.

Available models: Q - with a reduced power engine; S - with an engine with increased power.
