Description

Motor – Adopted by singlephrase asynchronous external rotor motor. The motor and impeller are directly pressed together by machine, so that can reduce the fan’s cubage, stay stable performance with high efficiency and long durability.

Impeller – Backwardcurved impeller matches well with the metal housing to maximize the air flow and efficiency, and to minimize the noise level.

Metal housing – Use fine material (quality deep-stretch cold-rolling steel) to stretching by machine. Spraying painted surface has strong rusty resistance. Computerized fluid-channel design makes maximum efficiency for the impeller
