ABSTRACT:
An improved air filter for use in a filtering system which uses reverse air pulse cleaning of a filter medium which is surrounded by and connected in sealed relation to an exterior housing. An energy absorption means is incorporated within the housing in such a manner as to prevent the direct flow of the reverse air pulses during cleaning from directly contacting the seal between the filter medium and the housing, whereby, the air flow is redirected through the filter medium before reaching the seal, thereby lessening the force upon the seal and preventing rupture thereof.
