Pneumatic brass silencing mufflers rely on porous sintered bronze air mesh to reduce air exhaust noise from pneumatic components. They can reduce noise from air exhaust to sound levels below 90 dBA for safe work environments and with minimal flow restriction. Available in 1⁄8, ¼, 3⁄8 and ½ in. pipe thread sizes or with #10-32 threads.
