Gas filtration module provides easy access to an in-line filter element by mounting it in a flexible pipe, which can be uncoupled and bent clear to remove the element

摘要

A gas filtration device (10) has at least one filter element (30) mounted in a bendably flexible housing (40),which is in turn fixed inside an open support frame (12,14,16). The flexible housing can be bent clear of the support frame to remove the filter element. The bottom of the flexible housing is clamped to the frame, and the top of the housing is attached to the top (14) of the frame by screw-threaded studs with wing-nuts, which when released allow the flexible housing to be bent between the frame uprights. The housing has a bottom inlet (18) for dirty gas entry, and an outlet port (22) for gas cleaned by diffusing through the filter element. The housing (40) may comprise a length of convoluted, flexible wall plastics pipe (claimed).
