Current draw




Air Flow




Shell: Use high quality tensile SGCC and tensile by mold, the surface have been spray processing, has strong ability to resist corrodes, with CAD design flow to enable to be maximum efficiency, Inlets and outlet diameter is design as the same pipeline standard, to easier to install, repair and cleaning


The actual simulation flow analysis, optimal design, Low noise powerful air volume


Use import bearing , low temperature rising and low noise. High torsion force, quickly startup and high efficiency


1. Housing: Formed and tooled by quality deep-stretch cold-rolling steel with plastic injection and strong rusty resistance surface. Computerized fluid-channel design, it makes high efficiency for the impeller. The outlet and inlet at the same diameter and standard design make it easy to install, maintain and clean. Specifications available are 100mm,125mm,150mm,160mm,200mm,250mm and 315mm.


2.lmpeller diameters:190mm,220mm,250mm,280mm, and 315mm are available. Backward-curved impeller matches well with the housing to maximize the airflow, efficiency and minimize the noise level.

3. External Rotor Motor: Adopted by single-phrase asynchronous external rotor motor. The impeller and motor are directly pressed so that impeller coule be driven by motor for small duct fans cubage, stable performance, high efficiency and durability.
