Vents - VKP centrifugal duct fan

The VKP centrifugal fan is a duct fan for a rectangular duct in ventilation ducts. Provides supply and exhaust ventilation with a low level of fan noise. Capacity up to 2970 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. It is designed to connect with rectangular ventilation ducts with a nominal cross-section: 400x200, 500x250, 500x300, 600x300, 600x350 mm.

Building

The fan housing is made of galvanized steel. Asynchronous two- and four-pole motors with an external rotor with backward curved blades were used. 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.
