Abstract
A pressure and heat molded polymer tube, formed of miniscule polyethylene beads, each in the vicinity of 115 um powder in diameter, which when compression molded forms pores that are of uniform diameter throughout their length within the range of 5 um-10 um, the tube having an upper flange, that mates within a correspondently shaped grommet, which when applied to the transverse plate of an air filtration housing, functions to cleanse highly efficiently the dust particles and debris from the air being filtered, when passing through the filtration system, so that such purified air can be discharged safely.
