DESIGN
The fan casing is made of steel with a polymeric coating. A thin steel connection plate is provided at the base of the fan.
MOTOR
The centrifugal impeller with backward curved blades is powered by means of the single phase motor with an external rotor. The motors are equipped with thermal overheating protection with automatic restart as well as ball bearings for a long service life. For precise features, safe operation and low fan noise, each turbine is dynamically balanced during assembly. Motor protection rating IP 44.
SPEED CONTROL
Smooth or step speed control is performed by means of a thyristor or autotransformer controller. Several fans can be connected to one controller assuming the total power and operating current do not exceed the rated controller values.
MOUNTING
The fan is mounted on the roof directly above the ventilation duct or shaft and is firmly fixed to the flat surface by means of the connecting plate. Electrical connection and mounting should be performed in compliance with the manual and wiring diagram on the terminal box.
