    Description
    APPLICATIONS

    • Combined supply and exhaust ventilation systems for various premises where high air flow at relatively low system resistance is required.

    • OVK fans can be used for the direct air exhaust or pressurization in smoke ventilation systems. 

    • OVK fan are suitable for outdoor wall mounting.
    DESIGN

    • The fan casing and the impeller are made of steel with polymeric coating. 
    • OVK fan terminal box is equipped with the cord for remote connection.
    MOTOR

    • The impellers are powered by two-, four- or sixpole, single or three phase asynchronous motors with external rotor and built-in thermal overheating protection depending on the model. 
    • Ball bearings in the motor provide long service life designed for at least 40 000 hours.
    • 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 if the total power and operating current do not exceed the rated controller values.
    MOUNTING

    • Fan is installed on the wall surface by means of a round OVK series mounting plate.

    • The fan is powered through the external remote terminal box.

    • Power supply and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
