Abstract
Exhaust air from an air tool or other air actuated device is directed into an air expansion chamber separated by slots from a second chamber containing a predetermined volume of small unconnected particles, such as small pellets of reground plastic scrap material. The plastic pellets or particles loosely fill the second chamber so that each particle is free to move in response to air flow between the particles so that the particles are self-cleaning. In the embodiment illustrated, all of the components of the muffler are formed of a plastics material, and a threaded tubular portion provides for attaching the muffler to an air actuated device.
