Description
EA4230-R Muffler, 3 inch With Relief Valve
The EA4230-R is an exhaust muffler used on compressed air equipment to help reduce exhaust noise and diffuse discharge air at the point of venting. It’s commonly applied on purge/exhaust outlets found on heatless desiccant dryer systems and related valve assemblies where controlling exhaust sound matters.
This version includes an integrated relief valve as part of the muffler assembly, combining exhaust silencing with an overpressure relief function at the exhaust location.
Key Features
- Quieter exhaust point: Helps reduce exhaust noise at purge and blowdown discharge locations.
- Improved operator area comfort: Diffuses discharge air to make exhaust points safer and less disruptive.
- Direct replacement part: Built for straightforward swap-out during maintenance.
- Integrated relief valve: Combines exhaust silencing with pressure relief in one assembly.
