Abstract
The present invention is directed toward a movable airborne contaminant control system having a retractable/extendable booth attached in a sealing manner to a ventilation unit, preferably mounted on wheels. The ventilation unit includes a filter assembly that opens into the work are formed by the booth. Front doors support air filters. In operation, the ventilation unit draws air in a longitudinal laminar flow over one or more work pieces. The filter assembly captures both particulates and VOCs to allow the exhaust air to include an extremely low contaminant load.

A mobile airborne contamination control system comprising:
- a ventilation unit having at least one exhaust fan;
- a filter assembly housed within said ventilation unit;
- and,
- a retractable contamination control booth including:
- a retractable/extendable frame having a plurality of pairs of opposing of risers, each said riser having a supporting rolling means, wherein each riser in each of said pair of opposing risers is hingeably attached to each adjacent riser;
- a plurality of joists, each of said joists attached to one pair of said plurality of pairs of opposing risers;
- a cover of flexible material draped over all of said opposing risers and thereby covering said retractable frame to form said booth having an enclosed work area;
- a flexible rear wall attached to said retractable/extendable frame and sealingly attached to said ventilation unit around said filter assembly, wherein said filter assembly opens into said retractable booth from said rear wall;
- and,
- a front wall of said booth having at least one front door, each of said at least one door having a section permeable to air flow.
A mobile airborne contamination control system comprising:
- a ventilation unit having at least one exhaust fan;
- and,
- a filter assembly housed within said ventilation unit.
