    Description
    APPLICATIONS

    • Exhaust ventilation system for various premises for roof mounting.
    • Compatible with Ø 200 to 500 mm round air ducts.
    DESIGN

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

    		  
    MOTOR

    • The impellers are powered with two- or four-pole, singlephase asynchronous motors with external rotor and built-in thermal overheating protection with automatic restart depending on the model.

    • Ball bearings in the motor ensure long service life.

    • Motor protection rating IP 24.
    SPEED CONTROL

    • Both smooth or step speed control is performed by means of the thyristor or autotransformer controller.

    • Several fans can be connected to one controller under condition that the total power and operating current do not exceed the rated controller values.
    MOUNTING

    • The fan is mounted on the roof directly above the ventilating duct or shaft and is firmly fixed to the flat surface by means of a connecting plate.

    • While mounting VOK fans directly onto the flat roof a supporting block shall be provided to prevent water and snow drops into the vent of the ventilation shaft.

    • Electrical connection and installation shall be performed in compliance with the manual and circuit diagram on the terminal box.
