Ircular duct fan

Product features:
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 fan¡¯s cubage, stable performance, high efficiency and durability.
4¡¢Connecting Box:Adopted by fire-resistant fiber PVC. Quality fire-proof, safety for usage and easy to disassemble.
