Inline Centrifugal

Impeller Type


Centaxial Fan, Direct Drive


The CDD centaxial fan is designed for continuous-duty operation in air moving systems handling clean air. Typical applications are industrial space ventilation exhaust or supply, industrial fume ventilation (where a suitable coating has been applied if the fumes are corrosive), air make-up, air conditioning, evaporative cooling, heat recovery systems, or as an exhaust fan on the clean air side of certain types of collectors and scrubbers.

The CDD features Aerovent’s backward inclined airfoil impeller for non-overloading performance, high operating efficiency and low noise. The CDD provides straight-through airflow and can be installed directly in a straight duct having the same size and shape inlet and outlet.
