Abstract
Dust filter in a vertical housing which is divided into a lower raw air section and an upper clean air section by a divider (2) which provides a number of equally spaced openings through which filter elements (5) are passed. The elements are held in position only by gravity and are open-ended in the clean air region. The fouled, outer, surfaces (22) are cleaned by sprays (10) which are placed symmetrically between the surrounding elements, cleaning fluid being sprayed radially through openings (17) immediately under the divider (2), i.e., in the raw air section.
