OV is an axial fan with low compression pressure in a steel housing and capacity up to 12 200 m ³ / h. Provides supply and exhaust ventilation for various types of rooms, where high performance is required with relatively low flow resistance. OV series fans are used in refrigeration to cool monoblocks with compressors. They can be used for simple air discharge through the wall. Designed for wall mounting - also on external walls, using a rectangular mounting plate.

Building

The fan and wing impeller housing is made of sheet steel with a polymer coating. The fan has asynchronous motors with an external rotor and thermal protection having an automatic restart. Ball bearings were used. Depending on the model, two or four pole motors are used, which can be in one or three phase versions.

Speed control

Speed regulation can be done smoothly (thyristor regulator), as well as stepped (transformer regulator). Fans can be connected by a pair of units to one controller, provided that the available power and current will not exceed the nominal parameter in the controller.
