Ultra Quiet Muffling Service

Thoroughly chosen by users on thousands of installations, the world-class Atomuffler® superbly quiets Exponetially Perceived Noise (EPNdB). The Soft Flow Atomuffler® satisfies the need to muffle explosive air exhaust noise discharged from valve exhaust ports to a comfortable quiet zone with optimized CV Flow Factor, thus substantially improving equipment performance.


Constructed with a unique expansion chamber, completely free of obstruction, exhaust air softly flows to the atmosphere free of noise, oil fog and contaminants, providing a clean comfortable productive work environment. Composed entirely of corrosion-resistant material for long life and maintenance-free performance, units are provided with a hex head, making it easy to attached to exhaust ports. They should be mounted in a protective position, free from excess vibration.


The Soft Flow muffler features special internally added acoustic treatment, achieves a higher degree of noise supression.
