Completely independent from power cords, air lines, and electricity, the PV10 vacuum operates off a propane power source backed by a heavy-duty engine. Combined with a 12V electric start, heavy-duty casters, ergonomic fiberglass frame, and full handle bards, the vacuum is easily portable to a variety of jobsite conditions. An oversized micro-clean filter is 99.9% efficient at 0.5 micron providing longer vacuum cycles and less filter maintenance. Ruwac USA. 413-532-4030.
