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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30 CFM rated airflow for reliable exhaust speed control\u003c\/li\u003e\n\u003cli\u003e1\/4 inch Male NPT thread for direct installation into standard exhaust ports\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in compressed air service\u003c\/li\u003e\n\u003cli\u003eCompact 1-9\/16 inch overall length fits tight valve and manifold installations\u003c\/li\u003e\n\u003cli\u003eRated for 35 degrees F to 300 degrees F operating temperature range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install component for pneumatic directional control valves, cylinders, and actuators with 1\/4 inch NPT exhaust ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMuffler Type\u003c\/strong\u003e: Speed Control Muffler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 30 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 300 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 35 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4420001450PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51755289248050,"sku":"4420001450PRO","price":21.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b56c3ff47b1236b2487282a7d8cf442.jpg?v=1788953152","url":"https:\/\/voomisupply.com\/products\/pro-source-4420001450pro-pneumatic-speed-control-muffler","provider":"Voomi Supply","version":"1.0","type":"link"}
