Pra / PRA-T
Very high-efficiency centrifugal fan for high flow rates at medium to high pressures.
Industrial Fans
The Pra / PRA-T range
Very high-efficiency centrifugal fan with a backward-bladed impeller for slightly dusty air. Working range covers small-medium-high flow rates at medium pressures. Suitable for pneumatic conveying, fumes and fine dust, and for conveying solids mixed with air, chips and sawdust (with non-through fan). Maximum air temperature 60°C; with cooling fan 300°C. Special constructions on request.
