It reduces exhaust noise at the motor outlet, helping maintain acceptable sound levels in industrial and commercial environments where GAST air motors are in continuous or intermittent service. At 3 inches in overall length and weighing 1 pound, this compact assembly installs directly onto compatible GAST motor exhaust ports. It is typically installed by maintenance technicians and industrial service professionals working on pneumatic motor-driven equipment.\u003c\/p\u003e\n\u003cp\u003eThis muffler assembly is intended for use with GAST air-actuated motor models in applications such as pneumatic pumps, agitators, and motor-driven tools found in manufacturing, laboratory, and light industrial settings. The part fits the 6AM, 8AM, 2567, and 3040 model series, making it a direct-fit replacement for worn or damaged exhaust mufflers on those units. Service intervals for muffler replacement are typically driven by increased exhaust noise, restricted airflow, or visible damage to the existing assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect-fit muffler assembly for GAST 6AM, 8AM, 2567, and 3040 air motor models\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length for compact installation on motor exhaust ports\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1 pound, reducing added load on motor hardware\u003c\/li\u003e\n  \u003cli\u003eReduces exhaust noise on air-actuated motor outlets\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual replacement service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GAST air-actuated motor models 6AM, 8AM, 2567, and 3040.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified maintenance technician or industrial service professional. Before replacing the muffler assembly, depressurize the pneumatic system completely and confirm the air supply is isolated and locked out. Use appropriately sized hand tools to remove the existing muffler and thread in the replacement assembly without over-tightening, which can damage exhaust port threads. Verify there are no air leaks at the connection point before returning the motor to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Muffler Assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 26101300\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GAST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AC990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GAST","offers":[{"title":"Default Title","offer_id":51702079586610,"sku":"AC990","price":135.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d52e735da20f0b9c54e40be1507a20c.jpg?v=1788408867","url":"https:\/\/voomisupply.com\/products\/gast-ac990-air-actuated-motor-muffler-assembly","provider":"Voomi Supply","version":"1.0","type":"link"}
