ABSTRACT:
An elongated hollow plastic body mounts a first plastic exhaust pipe of L-shaped configuration which passes completely through the body. Its inlet end is connected to the positive air pressure discharge of one vacuum pump connected to a closed dirty water vacuum dump tank for the hot water vacuum extraction machine. A second plastic L-shaped exhaust pipe is reversely oriented within the hollow body and has a plugged end abutting the side of first pipe near its inlet to the body. Both pipes are perforated within portions internal of the body and the hollow body is filled with glass wool to muffle the sound. The second pipe at its inlet end, is connected to the positive pressure air discharging from a second vacuum pump also connected to the vacuum dump tank. The exhaust from the vacuum pumps is effectively muffled with the air discharging through the perforations upstream of the plugged end of the second pipe passing through the glass wool, entering the perforations in the first pipe, and mixing commonly with the exhaust air flow carried by the first pipe.
