Adjustable Control For Logic Applications

Allied Witan Company’s Micro Miniature Muffler is designed specifically for low air volume use on pneumatic logic applications such as control, pilot, limit, zone, and relay valves. The muffler’s compact size allows installation in extremely tight quarters.


Attached directly to exhaust ports, noise reduction is accomplished by dispersing the exhaust air radially, minimizing sound intensity with negligible flow impedance. The Micro Miniature Muffler also can be used as a speed control to meter exhaust air flow.
