Conical Silencers

Product Overview

Pneumatic Silencers and Exhaust Mufflers for Air Valves

Pneuforce pneumatic silencers, also known as air exhaust mufflers or exhaust silencers, are designed to reduce the noise generated by exhausting compressed air from pneumatic control valves, cylinders and other air-operated equipment. Manufactured from high-quality conical brass bodies with sintered bronze elements, these silencers provide effective noise reduction while allowing unrestricted airflow from pneumatic exhaust ports.

Available in thread sizes from 10-32 UNF through 1/2" NPT, Pneuforce pneumatic silencers are suitable for industrial automation, pneumatic valves, air cylinders, FRL systems, compressors and general compressed air equipment where reducing exhaust noise improves workplace safety and operator comfort.

What Is a Pneumatic Silencer?

A pneumatic silencer is installed in the exhaust port of a pneumatic valve or other compressed air component to reduce the noise produced when compressed air is vented to atmosphere. The porous sintered bronze element diffuses the exhausting air, lowering noise levels while maintaining efficient airflow.

Pneumatic silencers are commonly referred to as air mufflers, exhaust silencers, exhaust mufflers or valve silencers and are used throughout industrial automation and compressed air systems.

How Sintered Bronze Silencers Work

The sintered bronze element is manufactured from compressed bronze particles that form a strong, porous structure. As compressed air passes through thousands of microscopic passages, the exhaust flow is dispersed, significantly reducing noise without creating excessive back pressure.

This design provides an excellent balance between effective sound reduction and unrestricted airflow, making sintered bronze silencers one of the most widely used exhaust solutions for pneumatic equipment.
