The RS114 sits one step below the RS112 in the Castair regulator lineup — a 1-1\/4\" body handling 400 CFM, rated to 250 PSI inlet. This is a main-header regulator for medium to large industrial air supply systems. It is appropriate where you need high-flow pressure regulation without the full 1-1\/2\" pipe sizing that the RS112 requires.\u003c\/p\u003e\n\n\u003ch2\u003eApplication and Sizing Context\u003c\/h2\u003e\n\u003cp\u003eThe RS114 fits installations where:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-1\/4\" header piping:\u003c\/strong\u003e Your supply header is 1-1\/4\" and you need pressure regulation at the main header before branching to drop legs and individual stations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400 CFM demand:\u003c\/strong\u003e Your aggregate downstream demand falls in the range serviced by 15–30 HP compressors or smaller duplex installations — the RS114's 400 CFM capacity matches without over-sizing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 PSI system:\u003c\/strong\u003e Full-system-pressure rated — safe to install directly on a high-pressure header without being the weakest component in the line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo-gauge preferred:\u003c\/strong\u003e Monitoring is done downstream, or a gauge will be added separately to the gauge port on this unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCastair Regulator Lineup — Where RS114 Fits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-RS12\u003c\/strong\u003e — 1\/2\" Std, 250 PSI, 104 CFM — individual station or small drop leg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-RS34\u003c\/strong\u003e — 3\/4\" Std, 250 PSI, 162 CFM — small header or high-demand station\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-RS10\u003c\/strong\u003e — 1\" Std, 250 PSI, 162 CFM — medium header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRS114 (*) — this unit\u003c\/strong\u003e — 1-1\/4\" Std, 250 PSI, 400 CFM — medium to large header, no gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRS112 (*)\u003c\/strong\u003e — 1-1\/2\" Std, 250 PSI, 500 CFM — large main header, no gauge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe filter\/regulator combination units (C-FRS12, C-FRS34, etc.) include a 5-micron filter and gauge — appropriate for individual stations.

Debris on the regulator poppet seat causes pressure creep and regulator failure. A good upstream filter protects the regulator investment.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e RS114* (no-gauge configuration)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet\/Outlet Size:\u003c\/strong\u003e 1-1\/4\" NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inlet Pressure:\u003c\/strong\u003e 250 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rating:\u003c\/strong\u003e 400 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge:\u003c\/strong\u003e Not included (gauge port present for field installation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Air Drying Equipment — Filters\/Regulators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From OEM Diagnostic Tools?\u003c\/h3\u003e\n\u003cp\u003eCastair air system regulators and filtration components stocked and shipped from our warehouse.
