ABSTRACT:
A filter for removing dust and solid particles from a gaseous fluid, such as air, comprises a case having opposite side walls which are symmetrical about a vertical plane. In each side wall there are inlet openings which open into inlet passages defined by inclined baffles which slope inwardly and upwardly to the outer face of filter material contained in the case and having spaced portions, one against each side wall of the case, with a cavity between them in communication with an outlet at the bottom of the case. Air first flows through those sections of the filter material providing the shorter paths defined by the baffles in flowing from the inlet openings to the outlet. As those sections become clogged with dust particles, air flows through adjacent sections so that the useful life of the filter is extended.
