Pro-source 4420003450PRO Speed Control Muffler 70 Cfm

Product Description

The PRO-SOURCE 4420003450PRO is a brass pneumatic speed control muffler designed to regulate airflow and reduce exhaust noise in compressed air systems. Threaded with a 3/4 inch Male NPT connection, it delivers a flow rate of up to 70 CFM while dampening exhaust sound at valve or actuator discharge ports. The all-brass construction provides durability in industrial and workshop environments. This muffler is rated for a temperature range of 35 degrees F to 300 degrees F, making it suitable for a wide range of operating conditions. It is installed by pneumatic system technicians, maintenance mechanics, and industrial equipment specialists.

This speed control muffler is used in pneumatic circuits where exhaust flow noise reduction and speed regulation are both required at a single fitting point. Typical applications include directional control valve exhaust ports, cylinder exhaust circuits, and compressed air distribution systems in manufacturing, maintenance, and automation environments. Its compact overall length of 2-3/8 inches and overall width of 1-1/16 inches allow installation in tight panel or manifold spaces where a standard muffler-only fitting would not provide speed control.

Key Features

• 3/4 inch Male NPT thread for direct installation into standard pneumatic valve exhaust ports
• 70 CFM flow capacity supports medium to high-volume pneumatic circuits
• All-brass construction resists corrosion and withstands industrial operating conditions
• Speed control muffler design combines exhaust noise dampening with flow regulation in one fitting
• Rated from 35 degrees F to 300 degrees F for broad environmental compatibility
• Compact at 2-3/8 inches overall length for use in space-constrained installations

Compatibility

Designed as a standard-style replacement or new-installation speed control muffler for pneumatic systems using 3/4 inch Male NPT exhaust port connections.

Installation Notes

Installation is performed by pneumatic system technicians or industrial maintenance mechanics. Depressurize and lock out the compressed air supply before servicing any pneumatic component. Apply thread sealant appropriate for compressed air service to the Male NPT threads before installation. Do not exceed the rated temperature or flow limits of the fitting.
