Applications
Combined supply and extract ventilation systems for various premises where high air capacity 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 as well as ball bearings for long service life. Motor rating protection IP 44.
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, refer page 136. The delivery set of VKOMz includes fixation brackets. The fan is powered through the remote terminal box.
Power supply and installation shall be performed in compliance with the manual and wiring diagram on the terminal box.
