Impellers for shaded-pole motors

Essima fan blades for shaded-pole motors
Where to buy

Intended use:

Essima axial fan blades are intended to be installed on the shaft of square shaded-pole motors of YJF series, this way creating one whole element of the cooling system that is widely applied in fan heaters, cooling equipment, evaporators and dehumidifiers of different kinds.

Design features:

Impellers are manufactured from aluminium sheets, thickness of which is perfectly selected to decrease vibrations induced by electric motors. Mounting dimensions are strictly standardized in fan blades that allows using different combinations of impellers and motors to achieve optimum performance. Depending on the position of the blade angle, the air flow can either be blowing (A) or sucking (V). Our company offers a model range with diameters from 154 mm to 300 mm with blade angle from 19° to 34°. Please see recommendations on how to choose blades angle depending on the required air flow and output power of the motor.
