It incorporates a differential pressure transmitter to sense air movement across a 12-inch diameter duct section, converting velocity pressure into a usable signal for building automation or controls systems. The unit operates across a velocity range of 400 to 4,000 FPM and is rated for air temperatures up to 200 degrees F. No actuator is included with this configuration. Licensed HVAC controls technicians and building automation specialists are the primary installers of this type of device.\u003c\/p\u003e\n\u003cp\u003eThe RAG12N is suited for installation in round ductwork in commercial and light industrial HVAC systems where accurate airflow monitoring is required. Typical applications include variable air volume (VAV) systems, air handling units, and ventilation control loops where measured flow data feeds back to a controller or BAS. The 12-inch duct diameter sizing makes it appropriate for medium-sized supply or return air trunk ducts common in commercial build-outs and mechanical rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound airflow station sized for 12-inch diameter ductwork\u003c\/li\u003e\n  \u003cli\u003eIntegrated differential pressure transmitter for direct velocity signal output\u003c\/li\u003e\n  \u003cli\u003eVelocity range of 400 to 4,000 FPM covers typical commercial duct conditions\u003c\/li\u003e\n  \u003cli\u003eRated for air temperatures up to 200 degrees F\u003c\/li\u003e\n  \u003cli\u003eNo-actuator configuration simplifies installation where actuation is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 12-inch round duct sections in commercial HVAC airflow measurement and building automation control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC controls technician or mechanical contractor familiar with duct instrumentation and building automation systems. Shut down the air handling unit and de-energize all associated controls before beginning installation. Follow applicable SMACNA duct construction standards and local mechanical codes for penetration, sealing, and support requirements. Refer to the manufacturer wiring diagram for signal output connections to the controls panel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round Air Flow Station\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVelocity Range\u003c\/strong\u003e: 400 to 4,000 FPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JOHNSON CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RAG12N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JOHNSON CONTROLS","offers":[{"title":"Default Title","offer_id":51283898892594,"sku":"RAG12N","price":1083.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279149.jpg?v=1781062715","url":"https:\/\/voomisupply.com\/products\/johnson-controls-rag12n-round-airflow-measuring-system","provider":"Voomi Supply","version":"1.0","type":"link"}
