APPLICATIONS
  • Combined supply and extract ventilation systems for various premises where high air flow at relatively low system resistance is required.

DESIGN
  • VKOM fan casings are made of steel with polymeric coating. 

  • VKOMz fan casing is made of galvanized steel and the impeller is made of aluminium.

  • The terminal box is fitted with a cord for remote connection.
MOTOR
  • Single-phase asynchronous motor is equipped with thermal overheating protection with automatic restart.

  • The motor is equipped with slide bearings.
  • Motor rating protection IP X4.
SPEED CONTROL
  • Both smooth and step speed control is performed with the thyristor or autotransformer controller.

  • Several fans can be connected to one controller in case the total power and operating current do not exceed the rated controller values.
MOUNTING
  • VKOM or VKOMz series fan is installed into the duct by means of clamps or directly inside the wall. 

  • RM reducers made of polymer-coated steel and RM...Zn made of galvanized steel are designed for connection of VKOM fans with 150, 200 and 250 mm round air ducts.

  • The delivery set of VKOMz includes fixation brackets.

  • The fan is powered through the remote terminal box.
