An exhausting valve or cylinder port can make a lot of noise, and contaminants can enter a pneumatic system though an unprotected opening. Exhaust silencers quiet the sound of the escaping air and protect the system from dirt and debris. These plastic NITRA silencers are available with NPT or R (BSPT) threaded connections.
NITRA pneumatic exhaust silencers (pneumatic mufflers) are available in brass cone, brass flat, plastic, and high-flow aluminum styles, with NPT, R (BSPT) or M5 threaded connections. Add these to the exhaust ports of NITRA directional control solenoid valves to reduce noise.
