Axial fans

Heavy-duty industrial centrifugal fans Compact industrial centrifugal fans Axial fans Plug fans Smoke extraction fans

Standard range covering up to 3600 Pa and 180 000 m³/h, impeller diameter up to 1250 mm and continuous operating temperatures up to 120 °C.
Our industrial axial fan product range is based on 3 standard product lines: For the field of low and medium pressure fanswe define a “bidirectional” product line suitable for continuous operating temperatures up to 120 °C. The medium pressure “unidirectional” fan line is suitable for continuous operating temperatures up to 80 °C. The medium and high pressure fans are defined by the application oriented arrangement of our impellers with the choice of three possible blade profiles, the respective matching casingtypes and the use of fixed guide vanes out of a large choice of options. Every selection is based on the aerodynamical data arising from the required fan curve and from the design adaptation to the most different customer requests.
