MINIMUM FLOOR SPACE COMMERCIAL AIR FILTER
First Claim
1. A minimum floor space air filter unit comprising:
- an outer housing defined by side walls, said side walls having a height and a base, said base having a width, said sidewall height being substantially greater than said base width;
said housing including an air inlet and an air outlet;
a blower mounted in said base,at least two elongated filters mounted within said housing, said elongated filters having filter media defining an interior core, said filter media having an exterior surface, said filters being stacked to define an elongated filter column;
said blower being positioned below said filters to draw air with entrained particulate into said air inlet and through said elongated filter column for exiting said housing through said air outlet, said entrained particulate being captured on said exterior surface of said elongated filters;
at least one nozzle positioned within said interior core of said filter media to pulse air from said interior core through said filter media to remove entrained particulate from said exterior surface.

Abstract
A minimum floor space air filter unit has an outer housing defined by side walls which has a height that is substantially larger than the base. A blower is mounted in the base. An elongated filter column is mounted in the housing. The blower is positioned below the elongated filter column to draw air with entrained particulate into an air inlet and through the elongated filter column for exiting the housing through an air outlet. Entrained particulate is captured on the exterior surface of the elongated filter column. At least one nozzle is positioned within the interior core of the elongated filter column to pulse air from the interior through the elongate filter media column to remove entrained particulate from the exterior surface.

20. A filter module for use in a minimum floor space air filter unit having a vertical elongated housing, said filter module comprising:
-
a generally tubular body portion defining an exterior surface and a core, said tubular body portion having a top ring and bottom ring, said top ring and bottom ring being adapted to support an adjacent stacked filter module; said filter module being adapted for insertion into the vertical elongated housing; said filter module having a filtering capacity that is less than the overall filtering capacity of the minimum floor space air filter, wherein stacking of said filter modules is required to obtain the desired filtering capacity.
