Applications
Combined supply and exhaust ventilation systems for various premises where high air capacity 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 44.
Speed control
Both smooth or step speed control is performed by means of the thymistor 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 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.
