The Gast B300A Filter Muffler Assembly at Kinequip is a dual-purpose component designed to either filter incoming air or reduce exhaust noise in compatible Gast air compressors and vacuum pumps. Its compact design and 1/4″ NPT threaded fitting make it easy to install across a wide range of systems.
When used as a filter, the B300A helps prevent contaminants from entering the pump, protecting internal components and extending service life. As a muffler, it effectively dampens sound from exhaust airflow, contributing to quieter operation in industrial and lab environments.
This assembly is compatible with multiple Gast models, including piston and rotary vane units such as the 1HAB, 2HAH, 3HBB, 4HCC, and 5HCD series. Built with durable materials and a 50-micron filtration rating, the B300A is a reliable solution for maintaining performance and reducing noise.
