Pro-source 4420001450PRO Pneumatic Speed Control Muffler

Product Description

The PRO-SOURCE 4420001450PRO is a brass pneumatic speed control muffler designed to regulate airflow and reduce exhaust noise in compressed air systems. With a 30 CFM flow rating and a 1/4 inch Male NPT threaded inlet, this muffler threads directly into exhaust ports on pneumatic valves, cylinders, and actuators. It measures 1-9/16 inches in overall length with a 9/16 inch diameter body and weighs 0.1 pounds. The brass construction provides corrosion resistance in typical shop and industrial pneumatic environments. Licensed pneumatic or mechanical technicians install this component as part of directional control valve assemblies and pneumatic circuit maintenance.

This muffler suits residential and commercial pneumatic control systems where exhaust silencing and airflow speed control are required. It is commonly installed on the exhaust ports of solenoid valves, manifold blocks, and pneumatic actuators. The operating temperature range of 35 degrees F to 300 degrees F makes it appropriate for both indoor and outdoor pneumatic installations in moderate climate conditions. Its compact size and standard NPT thread make it a straightforward drop-in component during routine valve servicing or system builds.

Key Features

• 30 CFM rated airflow for reliable exhaust speed control
• 1/4 inch Male NPT thread for direct installation into standard exhaust ports
• Brass construction resists corrosion in compressed air service
• Compact 1-9/16 inch overall length fits tight valve and manifold installations
• Rated for 35 degrees F to 300 degrees F operating temperature range

Compatibility

Designed as an OEM-style replacement or new-install component for pneumatic directional control valves, cylinders, and actuators with 1/4 inch NPT exhaust ports.

Installation Notes

Installation is performed by pneumatic or mechanical technicians. Depressurize and lock out the compressed air supply before removing or installing any pneumatic components. Thread the muffler hand-tight into the exhaust port, then snug with a wrench to the hex flat — do not overtighten brass fittings. Verify there are no air leaks at the connection before returning the system to service.
