fans-tech EC centrifugal blower fans

fans -tech EC fans (Electronically Commutated) means a fan which has a brushless,
permanent magnet Dc motor with onboard electronics available for controlling
a fan rotor. Common fans within the air conditioning and ventilation units are
generally motorized by asynchronous AC motors, responsible for driving the
impeller by belt technology. It takes up a significant amount of space in AC
devices which make installation complicated. Moreover, belt driven systems
need replacement and maintenance due to wearing parts. Asynchronous
drives are low in efficiency levels and have a negative implication in most
appliances’ power consumption.

How does EC affect energy efficiency?
EC fans can help in increasing the efficiency of any device such as in a
cooling system, if you keep the refrigerant pressure constant instead of rising
and falling it as the fans turn on and off, it will lessen the pressure on the
compressor which further result in energy saving.
The interface of electronics, aerodynamics, and motor means that EC fans not
only surpass in energy efficiency ability but due to the enhanced commutation
method and the aerodynamic impellers, they function very quietly. Moreover,
varied speed control of EC fan
