    Description
    APPLICATIONS

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

    • OV1 fans can be used for the direct exhaust of air. 

    • OV1 fans can be mounted onto the external walls.
    DESIGN

    • OV1 fan casings are made of steel with polymeric coating. 
    • The terminal box is fitted with a cord for remote connection.
    MOTOR

    • Single-phase asynchronous motor is equipped with thermal overheating protection with automatic restart.
    • The motor is equipped with slide bearings.

    • Motor rating protection IP 24.
    SPEED CONTROL

    • Both smooth and step speed control is performed with the thyristor or autotransformer 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 installed on the wall surface by means of square mounting plate.

    • The fan is powered through the remote terminal box.

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