ABSTRACT:
A filter assembly for an automotive air handling system includes a frame adapted for demountable attachment to the engine side of the automotive firewall, and a filter slidably received in the frame. Springs are provided at the bottom of the frame for ejecting the filter partially out of the frame so that air can bypass the filter when the filter is clogged. A latchable door covers the access opening of the frame, holding the filter down against the bias of the springs until clogging is detected by a pressure-sensitive diaphragm. The diaphragm controls a release mechanism which unlatches the door when clogging of the filter causes an increase in the differential pressure across the filter.
