Norgren MS003A Pneumatic Exhaust Muffler 60 Cfm 3/8 in Npt

Product Description

The NORGREN MS003A is a sintered bronze pneumatic exhaust muffler designed to silence and filter exhaust air discharged from pneumatic valves, cylinders, and actuators. With a 3/8 inch male NPT thread and a flow rating of 60 CFM, this muffler handles moderate to high-volume exhaust streams in both industrial and commercial pneumatic systems. The 40-micron sintered bronze element diffuses airflow, reduces exhaust noise, and captures particulates before they enter the surrounding environment. The Cv rating of 1.900 indicates low backpressure restriction, supporting consistent actuator cycle times. Licensed pneumatic technicians, maintenance mechanics, and automation technicians install this muffler as a direct inline exhaust fitting.

The MS003A suits pneumatic control panels, solenoid valve banks, directional control valves, and cylinder rod-end exhaust ports where noise reduction and exhaust filtration are required. It is appropriate for both light industrial and heavy industrial environments where maximum exhaust temperature does not exceed 176 degrees F (80 degrees C). The compact 1/4 inch body diameter and 0.69 inch hex allow installation in tight manifold configurations with a standard open-end wrench.

Key Features

• Sintered bronze element provides 40-micron particulate filtration on exhaust discharge
• 60 CFM flow capacity with a Cv of 1.900 minimizes backpressure on actuators
• 3/8 inch male NPT thread fits standard pneumatic valve exhaust ports
• Rated to 176 degrees F (80 degrees C) for use in warm industrial environments
• Compact 1/4 inch diameter body suits space-constrained manifold or valve body installations
• 0.69 inch hex allows installation with a standard open-end or combination wrench

Compatibility

Designed as an OEM-style replacement exhaust muffler for pneumatic directional control valves and actuator assemblies equipped with 3/8 inch female NPT exhaust ports.

Installation Notes

Installation is typically performed by pneumatic technicians or industrial maintenance mechanics. Before installing or removing this muffler, depressurize the pneumatic circuit fully and lock out the compressed air supply per site LOTO procedures. Apply thread sealant tape appropriate for compressed air service and hand-tighten before applying wrench torque to avoid cross-threading the sintered element body. Inspect the element periodically for compacted particulates that can increase backpressure and slow actuator response; replace the muffler if flow restriction is evident.
