Abstract (en)
[origin: WO2016179473A1] The present invention is directed to an axial or in-line type blowervac that switches between a blowing operational mode and a vacuum operational mode by moving a baffle within its housing to cover an air inlet or air exhaust depending on the operational mode selected. In the blow mode, a fan assembly is driven in a first direction to blow air out of an airpipe attached to a front portion of the housing. In a vacuum mode, the fan assembly is driven in a reverse direction, and air and debris are pulled in through the airpipe.
