Applications

Exhaust ventilation system for various premises suitable for roof mounting. Compatible with Ø 200 to 315 mm round air ducts.

Design

The fan casing is made of steel with polymeric coating, impeller is made of aluminium.

Motor

Single-phase asynchronous motor with external rotor and built-in thermal protection with automatic restart. Ball bearings ensure long service life. Motor protection rating IP 44.

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 under condition that the total power and operating current do not exceed the rated controller values.

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 VOK1 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 be performed in compliance with the manual and wiring diagram on the terminal box.
