Description
APPLICATIONS
  • Combined supply and exhaust ventilation systems for various premises where high air flow 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-, 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 X4.
SPEED CONTROL
  • Both smooth or step speed control is performed by means of the 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
  • 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.
