BACKWARD BLADE FLAT PROFILE
- VBR series
The VBR series characteristics are:
- High efficiency (up to 82%) allowing to reach
high savings in the consumption of electricity
- Low noise. For a fan the source of noise is
mainly the air turbulence created by the impeller.
The VBR series has been created to obtain the
lowest noise thank to the aerodynamic profile
of the inlet cone and of the static and dynamic
balancing of the impller.
