The Allied Gomco 01-90-3060 is a specialized 1/4" NPT diaphragm muffler designed for portable and tabletop aspirators, including the popular Gomco Model 300 series. This component is installed on the pump's exhaust port to significantly reduce the noise generated by the reciprocating motion of the diaphragm. By dampening acoustic vibrations and smoothing out the exhaust air flow, it helps maintain a quieter clinical environment for both patients and medical staff. Its durable threaded design ensures a secure, leak-proof attachment that can withstand the continuous pressure cycles of heavy-duty suction units.
