The BESL04 Speed Control Silencer is a heavy-duty, dual-function pneumatic accessory designed to reduce high-decibel exhaust noise while controlling air flow discharge. Featuring a male 1/2" thread (PT / BSPT / NPT), it screws directly into larger exhaust ports on pneumatic control valves, air cylinders, solenoids, and pneumatic tools.
Constructed with a heavy-duty brass base and a porous sintered bronze filter element, the BESL04 includes an integrated brass adjustment screw and hex locknut. This mechanism allows operators to fine-tune exhaust airflow—effectively acting as a speed controller for connected cylinders—while filtering out dust and particulates from entering the valve assembly.
