The VKM centrifugal fan is a duct fan for ventilation system in round duct. Provides supply and exhaust ventilation with a low level of fan noise. Capacity up to 5260 m ³ / h. The fan is used in ventilation of individual rooms, buildings in collective housing and public utilities. Adapted for installation at any angle relative to the fan axis.

Building

The fan housing is made of steel with a polymer coating. 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; E - with economical mode of operation; S - with an engine with increased power.
