SMM series metal pneumatic exhaust mufflers reduce noise while offering high air flows. They are available in 3/8, 1/2, 3/4, and 1 in. sizes. Housings are made from cast aluminum. Replacement porous plastic elements separate easily, allowing replacement of clogged or dirty elements without replacing entire muffler.
