Description

The impellers are factory set to the exact blade angle. The direction of the air stream is indicated on the fan unit by an “arrow.” The unit allows installation at any angle.
- According to IEC 34-1 standard
- The impeller assembly is dynamically balanced closely to the ISO 1940 requirements
- Integral overheat protector is fitted in the motor
