ABSTRACT:
An improved industrial filter apparatus for separating particulate material from air and/or other gases is disclosed. A plurality of individual filter elements are enclosed in a housing which admits particulate laden gases to enter the top of the housing and flow downwardly, radially inwardly of the individual filter units so that particulates accumulate on the exterior of the filters. The interior of a plurality of filters communicate with a common clean air duct functioning as a plenum which is closed at one end and open at its opposite end to a clean air outlet fitting in the side wall of the housing. Also within the clean air duct are a plurality of venturis communicating with the duct and the interior of each filter. A compressed air source is arranged to fire pulses of air upwardly through the venturis to remove the particulates from the exterior filter surface. The generally downward flow of dirty air assists in conveying the particles removed from the filters to the bottom of the housing where they are periodically removed through a conventional valving arrangement.
