External rotor portable axial fan with automatic shutter series is used for welding factory exhaustion,communication cable maintenance,ship building,underground mine and so on. The principle of operation is the same as the ordinary axial fan,but more larger volume and higher pressure with the advantages of small vessels ,low noise,light weight,high efficiency and mobile portability. Can make the distance or deep pumping operation area of wind when with telescopic type ventilation hose.
External Rotor Axial Fan is a new product developed by our company by combining technology and talent advantages of many domestic colleges through repeated research and trail production. The impeller is directly fixed on the excircle to make axial size smaller. Its successful development is a key breakthrough of axial flow fan and achieves internationally advanced level. These fans are featured by high efficiency, whole sealing, low noise and vibration, short axial size and maintenance prevention, so it has wider applicable fields, can replace the conventional axial flow fan. External Rotor Axial Fan also can be used for kitchens, industrial and mining factories and other places with serious oil, soot and dust.
Operating Environment: Elevation: below 4,000m, air humidity: less than 90ºC and ambient temperature: -25ºC~+60ºC for general products, products used in unconventional environment also can be customized.
