Abstract
An air filtration unit for use in a work environment includes a housing disposed with an air filtration system and light source. The housing includes a handle and corner caps to prevent damage and provide stability. The air filtration system draws air into the housing, via a blower, through a first and second inlet gate, the air is at least partially filtered by a first and second filter assembly, which provide a two stage filtering, and then the at least partially filtered air is blown through an exhaust conduit back out into the work environment.
Claims24
An air filtration unit for use in a work environment, comprising:
- a housing including a plurality of panels generally configured in a triangular shape;
- a two stage air filtration system, coupling a first filter assembly with a first end panel and a second filter assembly with a second end panel, the first and second filter assemblies being disposed within the housing;
- a blower assembly, including a motor, disposed within the housing, the blower assembly for drawing air from the work environment through the first and second filter assemblies into the housing;
- an exhaust conduit coupled with the blower, the exhaust conduit for allowing the blower assembly to blow the at least partially filtered air back out into the work environment;
- a light assembly disposed in the housing, for providing light to the work environment;
- and
- a plurality of extruded tube assemblies for coupling the plurality of panels of the housing together,
- wherein the two stage air filter system at least partially filters the air from the work environment within the area illuminated by the light assembly.
The air filtration unit of claim 6, further comprising:
- a first selector assembly for selecting the operation of the motor of the blower assembly;
- and
- a second selector assembly for selecting the operation of the light assembly.
An air filtration unit for use in a work environment, comprising:
- a first end panel and a second end panel coupled via a plurality of extruded tube assemblies with a first side panel, a second side panel, and a bottom panel, the first and second end panels for providing an inlet gate for the air in the work environment;
- a first filter assembly including a first coarse filter and a first fine filter, coupled with the first end panel, the first filter assembly for providing a two stage filtering of air in the work environment;
- a second filter assembly including a second coarse filter and a second fine filter, coupled with the second end panel, the second filter assembly for providing a two stage filtering of air in the work environment;
- a light assembly coupled with the bottom panel, including a lamp plate, the light assembly for providing light to the work environment;
- a blower assembly including a motor and an exhaust conduit, coupled with the lamp plate, the blower assembly for drawing air from the work environment through the first and second filter assemblies and blowing the at least partially filtered air back out into the work environment via the exhaust conduit;
- and
- a plurality of corner caps coupled with the first and second end panels, the plurality of corner caps for protecting the panels of the air filtration unit,
- wherein the first and second filter assemblies at least partially filter the air from the work environment within the area illuminated by the light assembly.
An air filtration unit for a work environment, comprising:
- means for filtering air in a work environment;
- means for lighting the work environment;
- and
- means for housing the air filtration means and the lighting means;
