ABSTRACT:
A muffler for equipment powered by compressed air, the muffler comprising a flexible muffler body formed from a sufficiently resilient material to resiliently deform under the influence of an exhaust air stream from an air motor, the body having an inlet and an outlet; a plurality of flexible baffles located within said body to muffle the sound of the air powered equipment; and an oil mist remover extending at least partially through said body, said oil mist remover being sized and shaped to prevent trapped oil from being re-misted by said exhaust air stream.
