Medium Pressure Industrial (MPI) Fan

This series is used in clean-air, medium pressure industrial applications where high efficiencies are required. MPI fans can also be used for light pneumatic conveying and high temperature applications (up to 550°C).

Please refer to the fan range guide alongside for a visual impression of this versatile single inlet fan. Relatively high pressure and volume capabilities mean that this fan is employed extensively in light to heavy industrial applications.

The standard range consists of impeller diameters Ø250 mm direct driven fans up to Ø2100 mm heavy industrial duty belt driven fans. For the environmentally conscious engineer, this range offers high efficiencies and comparatively low noise levels.
