High Efficiency EC Centrifugal Fans For Indoor Air Purification 82W
EC Centrifugal Fans Description
Backward curved EC Centrifugal Fans are used primarily for intake suction and do not require a scroll housing. They have high hydraulic efficiency. They usually offer a quiet and compact air moving solution. The Permanent Split Capacitor motors provide reduced operating costs and longer service life. Ball bearing construction allows multiple mounting options. Backward centrifugal fans have low profiles that do not need scroll housing. Air is discharged 360° radially from the impeller wheel. These units operate very efficiently at high pressures.

EC Centrifugal Fans Control options
To control the motor accurately and efficiently the integrated electronics have to continuously monitor the motor speed and adjust the control input. By making this circuitry available to external sources it’s possible to provide simple speed control options. Dependent on the motor type, any sensor which can provide a 0-10V/PWM or 4-20mA input can be directly connected to provide closed loop control for temperature, pressure or whatever parameter you choose to measure. No need to worry about DC supplies for the sensors either, this is provided by another connection on the motor. In fact, simply connect a potentiometer and you have infinitely variable speed control. No triacs, no frequency inverters and no whining noises! An EC motor under speed control is virtually silent.
