High velocity filter

Claim 1

In a high velocity air handling assembly as for conditioning air in industrial plants which permits entry by service personnel within the assembly having an insulated housing carried by a structural base, a filter section comprising: a transverse grid formed by intersecting flat longitudinal metallic structural members defining a plurality of intersecting rows of aligned closely adjacent openings, said openings having inner sides conforming generally to the configuration of an opening of a sock filter; said structural members defining longitudinal vertical and longitudinal horizontal flanges; a plurality of elongated sock filters having an open base on one end tapering inwardly therefrom toward and being closed on the other end; sealing strip means carried by said metallic structural members about said inner sides for attaching individual base portions of said sock filters entirely about the base, entirely about said sides so that the bases of said sock filters are open for receiving high velocity air; and structural means securing said grid about marginal portions thereof across said housing and said base so that said grid serves as lateral bracing for said housing and as a support for said sock filters.
