Belt driven fan boxes
from 1.500 to 16.000 m³/h

The frame is made from galvanized steel.
A side panel can be opened to inspect the unit.
The acoustic insulation is obtained by an adequate thickness of polyester.
The fans are double inlet forward curved centrifugal type with statically and dynamically balanced wheels reducing vibrations and noise. Anti-vibrators, which attenuate any vibration transmission, have been placed between the frame and the motor-fan assembly.
The electric drive motors, of the three-phase type with class F insulation and protection degree IP 55, are placed on special adjustable slides, to allow proper tensioning of the driving belts.
A cable gland is fitted to the unit front panel for easy electrical connections.
