The exhaust gas diffuser and filter system for a pneumatic nail gun provides for the diffusion and filtering of exhaust gas, which is typically pressurized air, generated by the pneumatic nail gun during usage thereof. The system includes a diffuser plate adapted for covering the exhaust ports of the pneumatic nail gun, and further includes a bag formed from an air permeable material, allowing for further diffusion and filtering of the exhaust gas. The diffuser plate has a plurality of fluid passages formed therethrough, and is adapted for releasable mounting on the exhaust portion of the pneumatic nail gun. The plurality of fluid passages diffuses the exhaust gas produced by the pneumatic nail gun during use. The bag provides for further muffling of exhaust noise and diffusion of the exhaust gas, and further provides filtering thereof.

I claim: 1. A pneumatic nail gun exhaust gas diffuser and filter system, comprising: a pneumatic nail gun having a pistol grip and a pneumatic air chamber housing extending normal to the pistol grip, the pneumatic air chamber housing defining an exhaust opening for ejecting a jet of exhaust gas during a nailing cycle; a diffuser plate having a plurality of fluid passages formed therethrough, the diffuser plate being attached to the pneumatic air chamber housing and covering the exhaust opening, the plurality of fluid passages being adapted for diffusing the jet of exhaust gas released by the pneumatic nail gun during a nailing cycle; a bag having an upper closed portion and a lower open portion, the bag covering the exhaust opening of the pneumatic air chamber housing, the bag being at least partially formed from an air permeable material, the bag further muffling exhaust noise and diffusing the jet of exhaust gas to prevent dust and debris from being stirred up; and a cover member extending from said bag, the cover member covering the pistol grip and having releasable fasteners for securing the cover member to the pistol grip. 2. An exhaust gas diffuser and filter system for a pneumatic nail gun, comprising: a diffuser plate having a plurality of fluid passages formed therethrough, the diffuser plate being adapted for attachment to an exhaust portion of the pneumatic nail gun and for covering exhaust ports thereof, the plurality of fluid passages being adapted for diffusing exhaust gas released by the pneumatic nail gun; and a bag having an upper closed portion and a lower open portion, the bag being sized and shaped to cover the exhaust portion of the pneumatic nail gun, the bag being at least partially formed from an air permeable material, the bag further muffling exhaust noise and diffusing a jet of exhaust air to prevent dust and debris from being stirred up, wherein said bag further includes a strap secured to the lower open portion of said bag and extending outwardly therefrom, a first hook and loop fastener attached to the strap, and a mating hook and loop fasteners attached to an outer surface of the bag for attaching the lower portion of said bag to the pneumatic nail gun. 3. The exhaust gas diffuser and filter system as recited in claim 2, further comprising means for securing the lower open portion of the bag to the pneumatic nail gun. 4. The exhaust gas diffuser and filter system as recited in claim 3, wherein the means for securing the lower open portion of the bag to the pneumatic nail gun comprises hook and loop fasteners. 5. The exhaust gas diffuser and filter system as recited in claim 2, further comprising a cover member extending from said bag for releasably covering a gripping handle portion of the pneumatic nail gun. 6. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 5, wherein the cover member has laterally opposed first and second side edges, the first side edge being secured to a sidewall of said bag. 7. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 6, further comprising means for releasably securing the cover member to the gripping handle portion of the pneumatic nail gun. 8. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, further comprising means for securing said diffuser plate to the exhaust portion of the pneumatic nail gun. 9. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 8, wherein said diffuser plate has an axial bore defined therein, said means for securing said diffuser plate to the exhaust portion of the pneumatic nail gun comprising a bolt extending through the axial bore. 10. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, wherein the plurality of fluid passages each extend in a substantially axial direction through said diffuser plate. 11. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, wherein at least a portion of the plurality of fluid passages extend obliquely through said diffuser plate. 12. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, further comprising a cover member extending from said bag for releasably covering a gripping handle portion of the pneumatic nail gun, the cover member having mating hook and loop fasteners for releasably securing the cover member to the gripping handle portion of the pneumatic nail gun. 13. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 1, wherein the lower open portion of said bag is formed from an air-impermeable material. 14. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, wherein said diffuser plate has an axial bore defined therein, the axial bore being positioned substantially centrally in said diffuser plate. 15. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 2, wherein said diffuser plate is substantially circular in cross section. 16. An exhaust gas diffuser and filter system for a pneumatic nail gun comprising: a diffuser plate having a plurality of fluid passages formed therethrough the diffuser plate being adapted for attachment to an exhaust portion of the pneumatic nail gun and for covering exhaust ports thereof, the plurality of fluid passages being adapted for diffusing exhaust gas released by the pneumatic nail gun; and a bag having an upper closed portion and a lower open portion, the bag being sized and shaped to cover the exhaust portion of the pneumatic nail gun, the bag being at least partially formed from an air permeable material, the bag further muffling exhaust noise and diffusing a jet of exhaust air to prevent dust and debris from being stirred up; and a cover member extending from said bag for releasably covering a gripping handle portion of the pneumatic nail gun, the cover member defining a passage adapted for releasably receiving the gripping handle portion of the pneumatic nail gun. 17. The exhaust gas diffuser and filter system for a pneumatic nail gun as recited in claim 16, wherein said bag defines an open interior region therein, the open interior region of said bag being in communication with the passage defined by the cover member.
