Centrifugal fan in scroll casing VENTS VCUN series

Centrifugal fan in scroll casing VENTS VCUN series

Single-inlet scroll-type centrifugal fans with the impeller mounted on the three-phase asynchronous motor shaft. The air capacity is up to 19 000 m3/h. The fan is designed for supply and exhaust ventilation systems.


Description

Applications

Supply and exhaust ventilation systems for various premises. The fans can be used as components for ventilation and air conditioning units and are suitable for outdoor mounting.

Design

The fan casing is made of steel with polymeric coating. VCUN fan can be supplied both with the clockwise or counterclockwise rotation impeller. Each modification has few scroll positions to enable connection to the air ducts at any angle with 45° pitch distance.

Motor

The impeller with galvanized forward-curved blades is mounted directly on the 2-, 4-, 6- or 8-pole three-phase asynchronous motor shaft. Ball bearings in the motor ensure long service life. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating IP 54.

Speed control

Both smooth or step speed control is performed by means of the autotransformer or frequency controller. Several fans can be connected to one controller in case the total power and operating current do not exceed the rated controller values.

Mounting

The fan is suitable for installation in ventilating chambers, air conditioning units or can be used separately. In case of independent operation it can be connected to air ducts by means of both exhaust and intake branch pipes or exhaust branch pipe only. The exhaust and inlet branch pipes have rectangular or circular sections accordingly. Power is supplied by means of external terminals.
