Abstract

Abstract A refuse compactor which includes a housing, a vertically reciprocal compacting ram mounted within the housing, a waste receiving drawer slidable into a compacting position beneath the ram and a filtering system within the housing for neutralizing odors emanating from waste materials deposited in the drawer. The filter system, which may utilize activated charcoal as the deordorizing medium, includes a circulating fan mounted at the intake end of a duct positioned within the housing for circulating air within the housing through the duct and through a filter mounted in the outlet end of the duct. The fan is preferably driven by a two speed motor which may be controlled either manually by a three position switch, or automatically through actuation of the ram and through movement of the drawer.
