New ventilation units with improvements in tightness, robustness, ease of installation, and reparability. Ventilation units with low noise levels, made with aluminum profiles and sandwich-type panels, featuring 25 mm thick, non-flammable (M0) acoustic insulation made of fiberglass, backward-curved centrifugal impellers dynamically balanced.
Brushless EC direct current motor, high efficiency, low consumption, ball bearings, built-in thermal protection, and capable of operating at temperatures from -20ºC to +40ºC:
- Single phase version 230V±10% 50/60Hz, IP44.
- Three phase version 400V±10% 50/60Hz, IP54.
Speed fully adjustable via potentiometer located in the terminal box or via external control like the REB-ECOWATT. Analog input to control the fan with an external 0-10V signal.

Backward curved centrifugal impellers
To prevent accumulation of dirtiness.
Dynamically balanced. -
Low noise level
Internally lined with 25mm thickness of fireproof acoustic fiberglass insulation (M0) reducing the noise level significantly. -
Robustness
Quality finished aluminium profiles and plastic corners providing a great robustness. -
IP55 external terminal box
To facilitate electric.
