High Pressure Centrifugal Fans

High Pressure Centrifugal Fans

Featuring motors situated outside of the airstream and designed with inline installation in mind our AA series of high-pressure centrifugal fans provide superior air movement for industrial applications. Standard voltages 230/400V, 50Hz motors up to 4kW and 400-690V, 50Hz for higher powers. The AA range feature two pole, three phase asynchronous squirrel cage motors with class F insulation.

The fully welded housing is manufactured using rolling steel sheet with ultra durable aluminium impellers and an epoxy powder finish coating. Additionally, all of our high pressure centrifugal fans have an ingress protection rating of 55 (IP55). All of the AA high pressure centrifugal fan range are ERP compliant. Upon request 2-speed motors are available.

As an optional feature, a 60 Hz version is available on request.  There are also accessories within our industrial range to compliment the AA series which include outlet protection guards (RBS), connectors (EI), and safety switches (INT). As well as a frequency drive speed controller (SFC) which is ultra-compact, has a simple operating system and a wide range of functions. There are other accessories available for the AA series.
