Plastic Exhaust Silencers

Lightweight Exhaust Noise Reduction for Valves and Vacuum Ejectors

Plastic Exhaust Silencers are used to reduce exhaust noise from pneumatic valves and vacuum Venturi generators. Their plastic exhaust-silencer construction makes them a practical accessory for reducing noise or managing exhaust behavior in pneumatic systems.

The source category identifies general pneumatic and vacuum exhaust ports. Correct port size and adequate exhaust capacity are important so the silencer or vent does not create excessive back pressure.

Why Use This Exhaust Component?

• Helps manage pneumatic exhaust at the point of discharge
• Compact threaded installation
• Useful on valves, manifolds and other compressed-air equipment
• Can improve machine noise control and exhaust management
• Should be sized to avoid excessive exhaust restriction

Common Applications

• Pneumatic valve exhaust ports
• Cylinder and actuator exhaust circuits
• Valve manifolds
• Vacuum Venturi exhaust
• Air preparation and relief ports
• Industrial automation machinery
