ABSTRACT:
A trash compactor of the type comprising a hollow cabinet containing a reciprocally movable compaction plate for crushing and reducing the volume of waste materials deposited therein also includes a sanitary air filtration system for inhibiting the release or airborne particles beyond the confines of the cabinet. A removable air plenum assembly is mounted within the cabinet and has an air inlet in fluid communication with the interior of the compactor cabinet and an air discharge. Motor driven fans create a negative pressure within the cabinet and a series of in-line filters are disposed in the air flow path for capturing airborne particles greater than about 0.3 microns in size and for deodorizing the air exiting the system. The motor-driven fans operate continuously at a low speed when the doors of the trash compactor cabinet are closed and switched to a higher speed when the doors are open to thereby inhibit any outward distribution of airborne particles except through the filter.
