ABSTRACT:
A bag-type filter apparatus, whose gas-permeable tubular filter bags are cleaned by a periodic reverse purge flow of air directed into one end of the filter bag, has a combination filter bag support and air diffuser for each filter bag and which is characterized in that the support holds the filter bag in an open tubular configuration throughout the length of the filter bag, but the air diffuser is of shorter length than the filter bag to more effectively clean the filter bag.
