Abstract
The present invention is a mobile air contaminant control system that includes a filter assembly enclosed by a mobile outer chamber. The filter assembly is tapered to create a large volume air way downstream from the filter assembly that enables more even air flow and filter loading. One or more exhaust fans pull the air through the filter assembly and exhaust it to the exterior of the chamber. The system is functionally attached to an exterior structure having at least one air intake and housing a work piece. As airborne contaminants are generated from the work piece(s), the control system exhausts them from the exterior structure through the filter assembly and into the external environment.
Claims27
A mobile airborne contaminant control system comprising:
- an outer chamber including a front wall, a roof, a floor and at least two side walls and possessing a fan end and a door end opposite said fan end, said outer chamber enclosing:
- an intake filter system including:
- a top filter:
- a plurality of side filters, at least two of said plurality of side filters attached to said top filter and at least two of said plurality of side filters contacting said floor of said outer chamber;
- and,
- a back filter opposite said door end and functionally attached to said top filter and said plurality of side filters;
- wherein said intake filter system includes a tapered shape with the narrow end of said tapered shape proximate to said back filter and the wide end of said tapered shape proximate to said door end;
- at least one airway formed between said intake filter system and said outer chamber;
- at least one fan, said at least one fan located between said back filter and said fan end;
- at least one air exhaust system extending from at least one of said at least one fan and directing exhaust air from said at least one fan to the exterior of said outer chamber;
- and,
- at least two wheels operatively attached to said floor.
