The Gast D344B Felt Filter/Muffler at Kinequip is a compact intake component designed to reduce noise and filter incoming air in rotary vane pump systems. With a felt media housed in a cylindrical body, it traps airborne particles while minimizing acoustic output, helping maintain clean airflow and quiet operation.
The D344B features a 2.00-inch outer diameter and a 3.75-inch length, with a 1.75-inch inner diameter at both ends for secure fitment. It’s commonly used in OEM assemblies and industrial environments where low noise and clean intake are essential. This filter/muffler is a direct-fit replacement and must be purchased in quantities of six. Ideal for preventative maintenance, it helps extend pump life and improve system performance.
