Exhaust ventilation system for various premises. Suitable for mounting on any roof types as well as connection to Ø 150 up to 315 mm round air ducts.


The fan casing is made of steel with polymeric coating. A thin steel connection plate is provided at the bottom of VKMKp model.


The centrifugal impeller with backward curved blades is powered by means of the single-phase motor with external rotor. The motors are 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 of the fan, each turbine is dynamically balanced while assembly. Motor protection rating IP 44.

Speed control

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.


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.

Electrical connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
