ABSTRACT:
An air compressor apparatus including noise-reducing means for converting ambient air into compressed air includes an air compressor surrounded by a noise-reducing enclosure and a plurality of shock-absorbing means disposed between the air compressor and the enclosure. The enclosure includes a pair of interior baffle plates which divide the interior of the enclosure into an air inlet chamber, an air outlet chamber and an air compressor chamber therebetween. The air inlet chamber and the air outlet chamber are each open to the atmosphere at a first lower end and are each in communication with the air compressor chamber at a second opposite upper end. The enclosure further includes a fan positioned within the baffle plate between the air compressor chamber and the air outlet chamber which is operable to draw air in through the open end of the air inlet chamber across the air compressor chamber and out the air outlet chamber. The air inlet chamber and air outlet chamber are each lined with acoustical foam in order to absorb sound waves originating with the air compressor and passing through these chambers.
