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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch Male NPT thread for direct installation into standard pneumatic valve exhaust ports\u003c\/li\u003e\n  \u003cli\u003e70 CFM flow capacity supports medium to high-volume pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003eAll-brass construction resists corrosion and withstands industrial operating conditions\u003c\/li\u003e\n  \u003cli\u003eSpeed control muffler design combines exhaust noise dampening with flow regulation in one fitting\u003c\/li\u003e\n  \u003cli\u003eRated from 35 degrees F to 300 degrees F for broad environmental compatibility\u003c\/li\u003e\n  \u003cli\u003eCompact at 2-3\/8 inches overall length for use in space-constrained installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-style replacement or new-installation speed control muffler for pneumatic systems using 3\/4 inch Male NPT exhaust port connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by pneumatic system technicians or industrial maintenance mechanics.
