    APPLICATIONS

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

    • The fan casing and the impeller are made of polymer coated steel.

    • The fan casing sides have 30 mm deep corrugation for convenient attachment to the air ducts. 
    • The OVP series fans feature an external terminal box mounted to the fan casing.
    MOTOR

    • Depending on the model the fans are equipped with two- or four-pole single-phase asynchronous motors with an external rotor and integrated self-resetting overheat protection.
    • Ball bearings in the motor provide long service life designed for at least 40 000 hours.
    • Motor protection rating IP 44.
    SPEED CONTROL

    • Both smooth or step speed control is performed by means of a 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

    • The fan is attached to a wall or the ceiling by means of the mounting brackets (included).

    • The power is supplied via the side-mounted box. 

    • Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box.
