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.
