Festo U-1/4-20, Polyacetal 10bar Pneumatic Silencer

The Festo U-1/4-20 pneumatic silencer is a small yet essential component that reduces exhaust noise in compressed air systems. It is installed directly into exhaust ports on valves, cylinders, or air tools to quiet escaping air without affecting system performance. Rated for pressures up to 10 bar, it fits standard industrial pneumatic setups where noise control is required, but space is limited. This silencer is part of Festo’s U Series and is designed for everyday use in factory and workshop environments.

Core Features and Benefits of the Festo U-1/4-20 Polymer 10bar Pneumatic Silencer

The body is made from a durable polymer, keeping the unit lightweight while resisting wear from continuous airflow. Its compact size enables it to be installed in tight spaces where metal silencers or larger fittings may not fit.

• 1/4-inch threaded connection.
• Polymer housing.
• Compact and lightweight.
• Suitable for continuous exhaust airflow.
• Reduce exhaust noise from pneumatic valves.
• Improve operator comfort in work areas.
• Prevent dust movement caused by open exhaust air.
• Keep pneumatic systems compliant with noise limits.

Simple Exhaust Noise Control for Pneumatic Systems

When compressed air is exhausted directly into open space, it creates sharp noise and air turbulence. This silencer reduces that noise while still allowing air to escape freely, helping keep the system operating smoothly.

Field Application of the Silencer

It works well in systems that run continuously and require consistent, unrestricted exhaust airflow.

• Pneumatic control panels
• Automation systems
• Packaging and assembly machines
• General industrial air circuits
