Application

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.
