Abstract: A bag house (10) is composed of a plurality of filter bags (44) each engaged over the substantially open support frame (46). A solid band (98) defines a lower edge of the support frame (46). One or more elastic seals (90) are rolled over the lower end (106) of the bag (44) which surrounds the band (98). The assembled seals (90), filter bag (44) and frame (46) are then simply inserted downwardly into a circular receiving collar (40) surrounding an opening (38) through which flows gas laden with particulate matter. The particulate matter is collected by the filter bag (44) while the filtered air is allowed to flow through the air previous bag.
