Applications
Combined supply and extract ventilation systems for various premises where high air capacity at relatively low system resistance is required. Fans can be used for the direct air exhaust and are mounted onto the external walls.
Design
Fan casings are made of steel with polymeric coating. Decorative front panel is made of high quality plastic. The terminal box is fitted with a cord for remote connection.
Motor
Single-phase asynchronous motor with external rotor 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
The fan is installed on the wall surface by means of square mounting plate. 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.
