ABSTRACT:
An industrial vacuum cleaner for collecting fibers collecting lint and the like and using said fibers as a filtration medium for air being exhausted from the cleaning system. The apparatus includes a positive displacement pump which draws the lint-laden air into a cylindrical housing having a plastic bag positioned therein which has holes provided therein. The plastic bag is, in turn, carried into a woven filter bag which is, in turn, carried within a rigid cylindrical mesh liner. As a result, the lint collected is removed from the air and builds up along the side walls of the plastic liner providing a filtration medium for lint-laden air subsequently drawn therein.
