Quiet Flow mufflers/filters utilize porous sintered bronze directly bonded to nickel plated steel pip thread fillings to diffuse air and muffle noise from the exhausted ports of valves, cylinders and air tools. These units offer a combination of small size with the greatest possible sound deadening qualities to reduce exhaust noise to acceptable levels within OSHA noise requirements.
In addition, these units are used as filters for gasoline, oil and air. Standard unit contains a 40 micron element, and 20 or 90 micron units are available on special order. Model ASP-420 is a female thread (1/2" - 20) muffler for use on exhaust ports of most solenoid valves. It can be used with "exhaust to atmosphere" valves, including skinner, Peter Paul, Allied, KIP, Pre Dyne or any muffler using 1/2" -20 threads on the sleeve.
