ABSTRACT:
An air filtration system that reduces positive and/or negative resistance by eliminating duct work to and from the to-be-filtered room. The air filtering system forms a common wall with the to-be-filtered room permitting dirty air to move easily and quickly through to the cleaning process. Through the use of vertical baffles and reverse pulsed jets, debris is easily and efficiently collected in drawers or trays. Because of the modular design of the invention, it is easily placed on a trailer and transported to a locale which is to be cleaned within a flexible room (i.e. bridges, building exteriors, airplanes, etc.).
