Variable Speed Circular Duct Fan, EC Motor, Quiet for Kazakhstan & Kyrgyzstan

Circular Duct Fan is our newly developed series with advanced tec-hnology absorbed from oversea and domestic.

With standard size ,the inlet and outlet at the same diameter could be directly connected with the duct by saving cost in designing.

The new design of housing,together with high-efficient centrifugal impeller,and high-performance external rotor motor make our duct fan superior to others at the aspects of bulk, weight,vibration,noise,durability,efficiency and safety. Its widely used at hotel, auditoriums, supermarkets, stations, airportsand other public occasions

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.

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.

Connecting Box: Adopted by fire-resistant fiber PVC. Quality fire-proof, safety for usage and easy to disassemble.
