Centrifugal fans type K and KR are designed for heavy duty industrial applications with medium-low flow rate and where the complete reliability is considered essential.

Usual design conditions are:

1. volumetric flowrate up to 200.000 m3/h for K series and 120.000 m3/h for KR series
2. static pressure up to 1.850 mmH2O
3. installed power up to 1.000 kW for K series and 800 kW for KR series
