AN AIR BLOWER HAVE A MANUFACTURE MAXIMUM AIR VOLUMM AT SMALL IMPELLER FOR IMPELLER COVER

摘要

The present invention relates to a blower with an impeller case of the structure that can produce a large air volume with a small impeller , its main objective is to air flow, that is, while the desired use for the impeller per minute 10 , to provide an impeller that can be produced per minute, the air volume of less than 15 17 widely. The present invention relates to a blower with an impeller disposed in the outer case to protect the impeller, the impeller disposed at least on one end portion of the electric motor, to achieve this purpose; The blower is used for the impeller per minute and 10 ; Is characterized in that the air volume is determined by the specifications of the impeller, the impeller guide case. Accordingly, the impeller and provided to produce air volume per minute of air flow per minute while 10 used for the impeller 15 to the desired 17 widely employing the impeller and also with less capacity, and to achieve the desired air volume there is unnecessary waste of power and space and, at the same time minimizing vibration and noise, and to reduce possible benefits.
