Gast AF350 Muffler Assembly for 1AM 1UP Air Motors

Product Description

The GAST AF350 is a muffler assembly designed for air-actuated air motors. It attaches to the exhaust port of compatible GAST air motors to reduce operating noise and control exhaust airflow during operation. At 2.6 inches in overall length, the assembly is compact and integrates directly into the motor without additional hardware or adapters. Weighing 3 pounds, it is a straightforward replacement component suited for installation by maintenance technicians and industrial service professionals working on pneumatic equipment.

This muffler assembly is intended for use with GAST 1AM and 1UP series air motors. These motors are commonly found in industrial and commercial applications where compressed-air-driven rotary power is required, including light manufacturing, laboratory equipment, and process automation. The AF350 serves as a direct-fit replacement when the original muffler is damaged, clogged, or lost during a motor rebuild or service cycle.

Installation Notes

Installation is typically performed by maintenance technicians or industrial mechanics familiar with pneumatic motor service. Depressurize and disconnect the air supply to the motor completely before removing or installing any exhaust components. Thread the muffler assembly into the exhaust port by hand first to avoid cross-threading, then snug with an appropriate wrench. Do not overtighten, as the fitting material and port threads may be damaged if excessive force is applied.
