Super Quiet Flow Heavy-Duty Metal Pneumatic Silencers / Mufflers
  Units 1/8" through 1" feature a 50 mesh, self-cleaning, stainless steel screen, corrosion-resistant aluminum shell, high flow and minimal back pressure. When installed on the exhaust ports of pneumatic valves, metal pneumatic silencers are a quick and inexpensive way to help reduce work area noise. At the same time, they protect the inside of pneumatic valves from contamination which can enter through the exhaust ports.

Maximum supply pressure: 300 PSI
Operating temperatures: 35oF to 160oF
CAUTION: Operation at temperatures approaching
32oF could result in freeze up due to air line moisture.
