  • Suitable for any roof types as well as vertical ventilation shafts.
MOTOR
  • 2-, 4- or 6-pole single- or three-phase asynchronous motors with an external rotor and impeller with backward curved blades.
  • The motor is equipped with thermal overheating protection with automatic restart as well as ball bearings for long service life.
  • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
  • Motors protection rating IP44, IP54.
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 in case the total power and operating current do not exceed the rated controller values.
DESIGN
  • The fan casing is made of galvanized steel (VENTS VKHz).
MOUNTING
  • The fan is mounted on the roof directly above the ventilating duct or shaft and is firmly fixed to the flat surface by means of a connecting plate.
  • While mounting VKHz fans directly onto the flat roof a supporting block shall be provided to prevent water and snow drops into the vent of the ventilation shaft.
  • Electrical connection and installation shall beperformed in compliance with the manual and circuit diagram on the terminal box.
  • For connection of the fans to round air ducts use the following accessories: KKV damper, GVK flexible connector, FKV counter flange.
  • For mounting of the fans to flat surface use the mounting frame RKV.
