Medium-high capacity and medium-high pressure centrifugal fans with a backward curved impeller PR-F ≤110000 m³/h

• the PR-F series of centrifugal fans are designed to transport clean or very dusty air up to +60 °C. They are suitable for all industrial applications where medium-high air volumes and medium-high pressures are required. The series consists of different models with impeller diameters from 250 to 1400 mm. The backward curved impeller offers extremely high aerodynamic efficiency. The casing is easily adjustable to the required discharge angle in 45° increments, including 180° and 225° positions
• other modifications of the PS-L series:

1. PR-F INOX - centrifugal fans with stainless steel casing for the transport of corrosive gases or fumes up to +60 °C.
2. PR-F AT - centrifugal fans for the transport of clean or lightly dusty air and smoke up to +150-300 °C
3. PR-F ATEX - explosion-proof centrifugal fans for the transport of clean air or smoke up to +40 °C

• housing positions (price may vary when ordering with RD housing)::
