Pro-source 4420001850PRO Speed Control Muffler 20 Cfm

Product Description

The PRO-SOURCE 4420001850PRO is a brass pneumatic speed control muffler designed to regulate exhaust airflow and reduce noise in compressed air systems. With a rated flow capacity of 20 CFM and a 1/8 inch male NPT thread, it installs directly into valve exhaust ports, cylinder end caps, or manifold blocks. The all-brass construction handles operating temperatures from 35 degrees F to 300 degrees F, making it suitable for a wide range of industrial and commercial pneumatic applications. This muffler is installed by pneumatic system technicians and maintenance mechanics during valve replacement, cylinder servicing, or new pneumatic circuit assembly.

This speed control muffler is used in compressed air systems where exhaust flow restriction and noise attenuation are required at the point of discharge. Typical installations include directional control valves, air cylinders, and pneumatic actuators in light industrial, manufacturing, and mechanical room environments. The 1/8 inch male NPT connection is a common port size found on solenoid valves, manual valves, and cylinder ports throughout residential and commercial pneumatic control applications.

Key Features

• Brass construction for corrosion resistance and durability in compressed air service
• 20 CFM flow capacity suits standard 1/8 inch ported valves and actuators
• 1/8 inch male NPT thread for direct installation into female-ported exhaust outlets
• Wide temperature range of 35 degrees F to 300 degrees F supports varied operating environments
• Compact overall length of 1-5/16 inches and 1/2 inch hex for easy installation with a standard wrench

Compatibility

Designed as an OEM-style replacement or new-installation muffler for pneumatic valves, cylinders, and actuators equipped with 1/8 inch female NPT exhaust ports.

Installation Notes

Depressurize and lock out the compressed air supply before removing or installing any pneumatic fittings or mufflers. Thread the 1/8 inch male NPT fitting into the exhaust port by hand first, then tighten with a wrench on the 1/2 inch hex — do not overtighten brass fittings into aluminum or plastic valve bodies. Apply thread sealant tape compatible with compressed air service if required by the system design. Verify airflow direction and exhaust path are unobstructed after installation.
