Portable Blower/Vac

摘要

An improved convertible electric blower/vac. The blower/vac includes an improved air inlet cover with an adjustable choke member. The air inlet cover also includes a pressure ring for increasing the efficiency of the blower/vac impeller when the unit is operated in the blower mode. The blower/vac also includes a blower tube and a vacuum bag collar, each with resilient tabs that engage receptacles on the blower/vac to retain the blower tube and vacuum bag collar on the unit. The housing outlet of the blower/vac includes guides that interact with longitudinal ribs on the blower tube and the vacuum bag collar to reduce unwanted rotational deflection of the blower tube and vacuum bag collar when either is engaged on the housing outlet. The blower/vac includes an improved vacuum tube for use of the blower/vac in the vacuum mode.
