AAVA AAVC/N & AAVM High Pressure Centrifugal Fans
Available in Standard, ATEX and Stainless Steel Construction
Manufacturing Features:
Centrifugal fan with a fully welded Fe360 sheet steel housing.
Qualicoat polyester powder coating stoved at 200ºC, with an average film thickness of 70 microns. Average heat resistance of the coating is 180ºC with peaks of 200ºC.
High efficiency simple inlet backward impeller with self-cleaning system made of Fe360 sheet statically and dynamically balanced.
Impellers are painted with polyester primer that resists temperatures up to 300ºC.
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.
Standard orientation LG270.
Ideal for Higher Pressure Systems
The AAVA, AAVC and AAVM models are designed to achieve higher air pressure rates and overall system efficiency in industrial applications. The maximum working temperature for carried air is 130ºC and up to 60ºC for ambient air. ATEX versions are available on request suitable for both zone 1 and zone 2 environments.
AAVA: High pressure centrifugal fan with backward curved impeller
AAVC/N: High pressure centrifugal fan with backward curved impeller
AAVM: High pressure centrifugal fan with backward curved impeller
