Abstract
Mobile air cleaning apparatus comprising a base, a cabinet which is mounted on and extends upwardly from one end of the base, and a hood which is supported by the upper end of the cabinet and extends over the base. A circular air flow path is formed which includes the open space between the hood and the base, and ducts in the base, the cabinet and the hood. In the air flow path are particle filters, an activated carbon filter, and a blower. The base is mounted on wheels so that the entire apparatus is readily movable.

Mobile air cleaning apparatus comprising a substantially flat elongated base, a cabinet mounted on one end of said base and supported by said base, an elongated hood having one end thereof mounted on the upper end of said cabinet and supported by said cabinet, the other end of said hood extending over said base, the other end of said base having an air intake opening formed in the upper side thereof and said other end of said hood having an air outlet opening in the bottom side thereof, connected air flow passages in said base, said cabinet and said hood, said air flow passages being connected to said air intake and air outlet openings, a blower mounted in said air flow passages for moving air from said air intake opening, through said air flow passaees and out of said air outlet opening, at least one particle filter and at least one charcoal filter mounted in said air flow passages upstream from said blower, and wheel means connected to said base for movably supporting said apparatus on a support surface, whereby said apparatus may be readily moved from one location to another.
Air cleaning apparatus comprising:
- (a) a base including wheels for supporting said base on the floor, said base being relatively low and sized to be moved under a vehicle, an air intake opening in the upper side of said base and a first air flow passage in said base, and a coarse filter mounted in said air intake opening;
- (b) a cabinet mounted on and extending upwardly from said base, said cabinet having a second air flow passage therein which is connected to receive air from said first air flow passage, an activated charcoal filter and a high efficiency filter mounted in said second air flow passage, and a blower mounted in said second air flow passage for moving air from said first to said second air flow passage and through said coarse, charcoal and high efficiency filters;
- and
- (c) a hood attached to and extending laterally from the upper side of said cabinet and over said base, said hood having a third air flow passage therein connected to said second air flow passage, an air outlet opening formed in te bottom side of said hood over said air intake opening, and a diffuser filter mounted in said air outlet opening.
