Abstract
A filter bag assembly of hybrid construction is disclosed that reduces the height of the filter bag assembly as well as its overall cost. The assembly indicates an elongated filter body portion, an end cap closing at one end of the filter body, a collar disposed at the other end of the filter body. The collar is molded onto the filter body and an inner venturi portion molded therewith. The assembly also includes a fabric extension portion that is attached to the interior of the collar. This extension may have a diameter greater than that of the collar so as to permit the filter body to be used in a tubesheet opening that is usually larger than that of the collar diameter. A snap band is contained within the collar for retaining the assembly in a tubesheet opening.
