Abstract
A high efficiency, stepped-top cartridge filter with a separate flow transition insert for installation in a uniform circular or oblong hole of a baghouse tube sheet. The cartridge includes a tubular core supporting a tube of pleated filter media to form a pleat pack having a molded cap at its lower end A open-mouthed, molded top fitting includes an upper flange, a side wall and a stepped portion leading to the bore of the filter. The flow transition insert is pressed into the top fitting to create a seal with the hole in the tube sheet. The insert includes an aerodynamically contoured mouth leading to a bore corresponding to the bore of the filter and further defines an air passageway between the top fitting and the insert for supplying tertiary cleaning air to supplement the primary and secondary air flows during a cleaning cycle.
