    Description
    APPLICATIONS

    • Designed for supply and exhaust ventilation of various premises.
    • The fan can be used as a component for ventilation and air conditioning systems and is suitable for outside mounting.
    DESIGN

    • The fan casing is made of steel with polymeric coating.

    		  
    MOTOR

    • The impeller with forward curved blades made of galvanized steel is powered by 2- or 4-pole single phase external rotor asynchronous motor.

    • The motors are equipped with incorporated thermal overheating protection with automatic restart as well as ball bearings for long service life.

    • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembling.

    • Motor protection rating IP 44.
    SPEED CONTROL

    • Both smooth and step speed control is performed with the symistor or autotransformer controller. 
    • Several fans can be connected to one controller in case the total power and operating current do not exceed the controller rated 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 either both exhaust and inlet branch pipes or exhaust branch pipe only.

    • The exhaust and intake branch pipes have rectangular or circular sections accordingly.

    • Power is supplied by means of the external terminals.
