/ / / BESL Speed Control Silencer

Speed control silencer (flow control muffler) provides an infinite variation of metering air flow at an acceptable sound level on exhaust ports of air valve with complete safety. Speed control silencer (flow control muffler) can also be used as filters to protect pneumatic valves by preventing dirt and other foreign matter entering the system. With linear adjusting capability, the speed of the cylinder can be decreased by adjusting the integrated screw. When optimal exhaust rate is reached, the lockout may be adjusted to prevent accidental adjustments due to vibration or other means. The noise absorbing material is made of sintered brass and the base is made of brass.

Available thread types and sizes:

• PT, R, BSPT; NPT; BSPP, G; Metric Thread
• 1/8" to 2", M8 to M20
