Ec DC AC Motor Highr Quality Impeller Single-Inlet Centrifugal Blower Fan

All of our fans are currently using the external rotor structure.  External rotor motor powered centrifugal fans have the advantage of compact structure, reliable operation, low noise, easy installation and high efficiency, ect.  Our centrifugal blowers are available in single-inlet and double-inlet types, both of them can be made into AC, DC and EC models.

Currently our company sells single inlet blowers with impeller diameters from 120 to 200mm and airflow from 200m3/h to 960m3/h;  For the double inlet models, as the name describe, we can see that they have two air inlets, we currently produce models with diameters of 120mm, 133mm and 146mm and airflow from 377m3/h to 1041m3/h.

The rotor material we make with is cast aluminum or carbon steel.  And the material of the housing we choose is relatively strong carbon steel, which with high quality galvanized steel impeller inside with it.  Beside these, we are also make them with long lifespan maintenance free ball bearing.
They are mainly used for the places which requests large airflow, high static pressure, system resistance, small internal space.  For examples: like coil units, ventilation units, roof fans and so on.
