Filter Unit for Rechargeable Dust Collector

Abstract

This article is a filter unit that is detachably installed inside a portable rechargeable dust collector. As shown in the reference cross-sectional view A-A showing the functions of each part, a HEPA filter is housed in a space surrounded by side frames on all four sides, and the upper and lower surfaces are sealed with wire meshes. It is installed in a state where a leak prevention gasket installed on the lower surface of the side frames on all four sides is in contact, and the contaminated air that enters from the wire mesh (air inflow side) is purified by the HEPA filter and then discharged from the wire mesh (air outflow side).
