Claim:
A pneumatic power tool comprising: a housing assembly having a body, a cap member and a gasket assembly, the body defining a motor cavity and an inlet manifold, the cap member defining an air inlet port, the gasket assembly having a first portion and a second portion, the first portion being a band that is formed of a compressible material, the band being sealingly abutted against the body and cap member, the second portion being coupled to an interior region of the band and being formed of a porous material; a pneumatic motor assembly received in the motor cavity; an output member driven by the pneumatic motor assembly; and a trigger assembly coupled to the housing assembly and operable for selectively operating the pneumatic motor assembly; whereby pressurized air received into the air inlet port is filtered by the second portion of the gasket assembly and flows into the inlet manifold when the pneumatic motor assembly is operated.
