Abstract
A method of pulse cleaning filter media in panel, cylindrical, conical, or V-pack style filter in an opening of a tubesheet is provided. The method includes directing a fluid pulse at the filter media at an angle that is: (i) not normal to a plane of the opening of the tubesheet; and (ii) not in line with the general direction of the filtration flow through the filter media. An air cleaner is provided including a housing including a dirty air inlet, a clean air outlet, and an interior. A tubesheet is in the housing interior having a plurality of openings. In the plurality of openings of the tubesheet are mounted filters with filter media. There is a plurality of blow pipes, with each blow pipe being pointed to direct at a fluid pulse a respective one of the filters at an angle that is: (i) not normal to a plane of the opening in the tubesheet; and (ii) not in line with the general direction of filtration flow through the respective filter media.
