Abstract
Disclosed herein is a disposable lightweight filter assembly which has a high flow through capacity and which is adapted to be positioned in a relatively small inaccessible space. The assembly includes a cylindrical housing having an air outlet at one end, a plurality of air inlet apertures in the side wall thereof, an offset pleated hollow cone-shaped filter element positioned within the housing and a reuseable air inlet bonnet adapted to be releasably secured to the housing about the air inlet apertures therein for securement of the filter assembly to a hump hose or other air flow coupling. Additionally, the bonnet can include a tubular moisture separator entending from the upstream end thereof. The filter element is supported by one or more beads of an adhesive material circumferentially disposed about the interior and exterior sides thereof and is sealably secured at each end to the housing such that the interior of the cone encircles the outlet while the exterior thereof is inwardly spaced from the air inlet apertures.
