The Castair R25312HG30-230 is a 25HP 3-phase rotary screw air compressor configured with a 120-gallon horizontal tank on a 230V electrical supply. The horizontal tank design makes this unit practical for installations where ceiling height is limited — the lower profile slides under mezzanines, into corners, or along walls where a vertical tank simply will not fit. At 25HP, this compressor steps up meaningfully from the 20HP class, delivering noticeably more CFM for shops that are pushing the limits of a smaller unit during busy periods.

Key Features
- 25HP Rotary Screw Pump: Oil-injected rotary screw technology runs at 100% continuous duty cycle — no cool-down periods required between heavy use cycles
- 3-Phase 230V Power Supply: Requires 3-phase 230V service; verify your panel capacity and breaker sizing before ordering
- 120-Gallon Horizontal Tank: Horizontal orientation lowers the overall height of the installation, ideal for shops with low ceilings or space constraints near the roofline
- Load/Unload Control System: Automatic load/unload cycling matches compressor output to actual shop demand, reducing wear and energy consumption during slower periods
- TEFC Motor: Totally Enclosed Fan Cooled motor handles the dust and airborne debris common in automotive and industrial environments
- Air/Oil Separator: Controls oil carryover to protect pneumatic tooling and ensure cleaner compressed air delivery
- Thermal Overload Protection: Motor protection against overload and voltage irregularities extends equipment life

Applications
The 25HP horizontal configuration suits shops that need more output than the 20HP class provides but want the flexibility of a low-profile installation. Typical uses include:
- High-volume auto repair and collision shops running multiple bays simultaneously
- Spray booths with continuous paint and clearcoat operation
- Fleet maintenance facilities with heavy pneumatic tool use throughout the day
- Tire and wheel shops with multiple mounting and balancing stations
- Light manufacturing with multiple pneumatic assembly tools
- Facilities with low-ceiling compressor rooms where a vertical tank will not clear overhead obstructions
