It handles pressure control at 1\/2-inch drops and main lines where a separate upstream filter is already in place or where the air supply is already clean enough that additional filtration at this point is not required.\u003c\/p\u003e\n\n\u003cp\u003eAt 104 CFM and 250 PSI maximum, the C-RS12 covers most single-station and small multi-tool installations. If you need both filtration and regulation in one housing at this port size, the C-FRS12 combo unit gives you both with a gauge and 5-micron filter bowl in one package.\u003c\/p\u003e\n\n\u003ch3\u003eWhat This Unit Does\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Maintains downstream pressure at a set point through supply pressure fluctuations during compressor on\/off cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Included:\u003c\/strong\u003e Downstream pressure visible at the unit — no separate gauge installation needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulator Only:\u003c\/strong\u003e No particulate filter.
