“The Original”… Provides Up To 85% Noise Reduction And 94% Flow Factor

Thoroughly proven on thousands of installations, the world-class Atomuffler® Air Exhaust Muffler expertly reduces Exponentially Perceived Noise (EPNdB) without impeding equipment performance. Its design takes explosive air exhaust noise discharged from valve exhaust ports and muffles it with optimized Constant Velocity (CV) flow factor. Exhaust air flows softly to atmosphere free of noise, oil fog, and contaminates – providing a clean, comfortable and productive work environment.


The Atomuffler’s radical, full-flow design uses interposing sound waves, multiple-stage velocity deceleration, an obstruction-free expansion chamber and a porous disseminator (filter element) to completely dissipate harmful air exhaust blasts. A large peripheral exhaust surface area diffuses the air blast, further lowering velocity and reducing air noise. Standard Air Exhaust Muffler construction includes aluminum end covers, zinc-plated steel components and a cellulose fiber element.


The design is recommended for general purpose air exhaust applications for pressures up to 125 PSI.
