Castair C-RS10 — 1" Pressure Regulator with Gauge, 250 PSI, 162 CFM
The C-RS10 is a 1-inch NPT standard-size pressure regulator with gauge from Castair — regulation only, no filter bowl. It controls downstream pressure on 1-inch main lines or high-demand branch feeds where pressure regulation is needed and filtration is handled by a separate upstream filter or filter/regulator.
At 162 CFM and 250 PSI maximum inlet pressure, the C-RS10 handles the output of large commercial and industrial compressors. If you need both filtration and regulation in one unit at this port size, look at the C-FRS10 filter/regulator combo instead. The C-RS10 makes sense when you have a separate filter installed upstream and want to keep the two functions in separate serviceability zones.
What This Unit Does
- Pressure Regulation: Holds downstream pressure at your set point regardless of fluctuations in tank pressure during compressor duty cycles and peak draw.
- Gauge Included: Live downstream pressure reading at the unit. Verify your set pressure at a glance.
- Regulator Only: No filter bowl or particulate element. Install upstream filtration — a C-FS10 or C-FRS10 — if contamination control is required.
- 1" NPT Female Connections: Standard threading — connects directly to 1-inch pipe or fittings.
- 250 PSI Max / 162 CFM: Main-line capacity for large industrial and commercial installations.
