The “AFT” series fans are designed for applications requiring very high air flows and medium-low pressures, when it is impossible or unadvisable to couple the impeller direct to the motor.
They are normally used in the presence of:
large diameters (air coolers, heat exchangers, cooling towers)
dusty atmospheres
high temperatures of the air flow
low noise installations
need to set the motor outside the air flow for access
Supports and drives are sized by COMET according to criteria based on 20 years of experience and hundreds of installations. For some models the bearing blocks are designed and built entirely by COMET.
The “AFT” series fans are selected using the Comet’s dedicated software, which provides a clear and concise data sheet with operating curves, including electrical and noise level data, as well as preliminary outline drawing. The selection is based on five blade profiles, with number of blades varying between 3 and 12 blades. This versatility gives unrivalled design options when selecting a fan unit.
