AAZA High Pressure Centrifugal Fans
Available in Standard, ATEX and Stainless Steel Construction
Manufacturing Features:
Centrifugal fan made of Fe360 sheet steel.
Fully welded housing with qualicoat polyester powder coating stoved at 200ºC, with an average film thickness of 70 microns and an average heat resistance of
of 180ºC with peaks of 200ºC.
High efficiency simple inlet with curved, radial or open blade impellers made of Fe360 sheet steel, statically and dynamically balanced. Impellers are painted with polyester primer that resists temperatures up to 300ºC.
Standard orientation LG270. Models 400 to 630 allow for the orientation to be adjusted. The orientation is fixed in models 710 to 1000.
Standard asynchronous squirrel-cage motor with IP-55 protection and class F insulation. Manufactured with standard voltages: 230/400V 50Hz in 3~ motors up to 4kW and 400/690V 50Hz for higher powers.
Ideal for High Pressure Industrial Applications
The AAZA series are designed for inline installation and can be used in various high pressure applications including clean and dusty air transport, cooling of machines and parts, pneumatic transport and exhaust after filters, separators and cyclones. An ATEX certified version is available on request.
