175mm Ec Centrifugal Fans With Air Purification Pa66 Fresh Air System

EC Motor – Principle 
With an EC motor the electronic circuitry stands in lieu of the traditional mechanical commutation meaning the right amount is being supplied in the right direction at exactly the right time providing precise motor control

Energy savings : Minimum power consumption & better efficiency than AC equivalent.
Control : 100% speed controllable, not frequency dependant. Can be set-up for constant airflow or constant pressure applications, 0-10VDC or PWM control signal.

Compact configuration, convenient installation and credible running

Pressure high, airflow stable

Little noise, energy saving and highly active

Several speed rang, adapt to both frequency conversion and voltage transformation, speed changing active
