ECOFIT Centrifugal Blowers AC Double Inlet

Standard specifications:

Ball bearings.
Cl.F windings protected by impedance or by thermal cut-out.
Protection IP 44 (GDR and GDS) or IP 54 (GDF).
Balancing G2.5.
Galvanized steel impeller.
Steel painted black scroll.

Centrifugal fans with forward-curved impeller blades demand maximum motor power at the maximum airflow rate and zero static pressure.
Certain fan models have minimum pressure levels required the motors will not over-heat. Performance curves then terminate at minimum permitted pressure. Finger guards are available upon request.
ECOFIT motors are speed controllable by voltage variation, but where electronic controllers are used they must be designed for electric motor duty and be compatible with ECOFIT products.
Capacitors must be of the "motor run" type and be of the recommended value, voltage rating, and life expectancy.
The customer must test for motor total temperature in the application, with the worst operating conditions for the motor. ECOFIT should then validate the test results.
