High -efficient improvement fan that consumes slowly

The utility model discloses a high -efficient improvement fan that consumes slowly, including shell and blade, the one end of shell is opened to be had the inlet air channel and the other end to open there is the air -out passageway, the motor was put up the bolt fastening setting and in the inner chamber of the shell that inlet air channel corresponds bottom, was installed the dryer at the front end of air -out passageway. Through improving fan blade profile and structure, increased the fan volume of airing exhaust, reduced the energy consumption, also make the air current steady more orderly. Connected mode through improving the adjustable angle between fan blade and the wheel hub has realized fan blade and wheel hub separation production simultaneously to according to actual need changes the installation angle of fan blade, and according to corresponding motor the power adjustment motor model, plays energy -conservation and reduces the effect of overlapping investment. Through adopting glass steel matter and SMC mould pressing technology, use except the ventilation that makes the fan can satisfy under the ordinary operating mode simultaneously, can also satisfy moist A corrosive environment and have apparent the operation requirement of special operating modes such as dust.
