      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 steel with polymeric coating. VKF fan is fitted with the external terminal box mounted on the fan casing.

      Motor

      The impellers are powered by two- or three-pole, 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

      VKF fan is installed into the duct by means of connecting flanges. 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.
