ProTeam Vacuums are equipped with a unique Four Level® Filtration system. This system captures tiny dust mites, bacteria, and floating particles – which can cause sick building syndrome and unhealthy air. Secondly, ProTeam's unique method of suction-vacuuming cleans carpets, hard floors, and other surfaces without stirring up dust – so the air stays cleaner, the furniture collects less dust, and operators can work without breathing unhealthy air. Fits Super CoachVac, MegaVac, LineVacer.
