Castair C-RE14 — 1/4" Mini Regulator with Gauge, 150 PSI, 38 CFM
The C-RE14 is a 1/4-inch NPT mini-size pressure regulator with gauge from Castair. It provides downstream pressure control on light-duty drops and single-tool installations where the line pressure exceeds what the downstream tool or component requires. No filter bowl — regulation only, in the most compact form factor in the Castair regulator lineup.
At 150 PSI maximum inlet pressure and 38 CFM, the C-RE14 handles one light pneumatic tool at a time. It is commonly used at point-of-use drops for die grinders, air ratchets, brad nailers, inflation equipment, and similar low-demand tools where you want precise pressure control without the added bulk of a filter/regulator combo.
What This Unit Does
- Pressure Regulation: Downstream pressure set and held by the regulator. Maintains your target pressure even as supply pressure fluctuates during compressor duty cycles.
- Gauge Included: Live downstream pressure display at the unit. Set it once and verify anytime without additional instrumentation.
- No Filter Bowl: Regulator only — no particulate or moisture removal. Install a filter upstream if contamination control is required at this point.
- 1/4" NPT Female Connections: Compact mini-size body. Fits 1/4-inch pipe, fittings, and quick-connect adapters.
- 150 PSI Max / 38 CFM: Light-duty single-tool drops only.
