Product Overview

>> Backward / Forward Curved Centrifugal Fan with AC / DC / EC external brushless Motor

Mainly used in grain drying and and greenhouse ventilation. These are also common in air pollution control as well as heating, ventilation and air conditioning (HVAC) systems.
EC backward curved motorized EC impeller is a superbly crafted, precision balanced air-moving device that features superior performance and compact design.
By combining the efficiency of a backward curved centrifugal impeller with the advanced technology of an electronically commutated external rotor motor, new standards for energy savings and performance have been achieved.
