Abstract

An air cleaning apparatus is disclosed in several embodiments. In one set of embodiments there is described an air cleaning apparatus (20) in which air to be cleaned is drawn toward and through a filter (41, 42, 43) in a particular direction. Periodically, reverse pulses of air are directed through the filter (41, 42, 43) in a direction opposite to the normal flow to interrupt the flow of air and to dislodge collected particles from the uncleaned air side of the filter and to enable migration of the particles towards the downstream lower end of the filter (32). In accordance with other embodiments of the present invention, there is described the addition of inertial precleaner devices (319, 319a, 319b) located proximate the unfiltered side of each filter for inertially separating heavy particulate matter from the uncleaned air prior to filtration. In addition the inertial precleaner devices (319, 319a, 319b) may have closure means (328a, 261a, 514) operable during the periodic reverse pulse cleaning to remove the dislodged collected particles and prevent reentrainment on the filter (286, 306).
