Abstract:
1. An air filtration unit for use in a work environment, comprising: a housing including a plurality of panels generally configured in a triangular shape, the panels defining a first end and a second end, the first and second ends having a substantially triangular cross-section; a two stage air filtration system, coupling a first filter assembly with a first end panel at the first end and a second filter assembly with a second end panel at the second end, 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, the blower exhausting the at least partially filtered air via the exhaust conduit in a direction substantially perpendicular to a direction of incoming airflow; 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.
