The Castair R25312VG30-230 is a 25HP 3-phase rotary screw air compressor with a 120-gallon vertical tank, wired for 230V 3-phase service. The vertical tank keeps the floor footprint compact while still providing 120 gallons of storage to buffer demand spikes when multiple tools are running at once. At 25HP, this is a serious production-grade compressor — the kind of unit a shop installs once and does not think about again for years, as long as maintenance is kept up on the oil and separator elements.

Key Features
- 25HP Rotary Screw Pump: Oil-injected rotary screw design rated for 100% continuous duty — appropriate for all-day shop and production use without thermal limitations
- 3-Phase 230V Power Supply: Requires 3-phase 230V at the panel; verify breaker sizing and wire gauge before installation
- 120-Gallon Vertical Tank: Compact floor footprint with maximum storage — the right choice when ceiling height is not a constraint and floor space is limited
- Load/Unload Control: Automatic controller cycles the compressor between full load and unload modes based on receiver pressure, saving energy during low-demand periods
- TEFC Motor: Sealed against dust and debris intrusion — appropriate for shop, garage, and light industrial environments
- Integrated Air/Oil Separator: Keeps oil out of the compressed air stream to protect downstream equipment and air quality
- Pressure Relief and Safety Controls: Standard safety equipment for ASME-compliant tank installations

Applications
The 25HP vertical configuration is the go-to choice for shops that need maximum output in a compact footprint. Use cases include:
- Multi-bay auto repair shops with consistent heavy tool use throughout the day
- Body shops running booth and prep work simultaneously
- Fleet maintenance facilities with multiple pneumatic impact wrenches in constant use
- Industrial operations with sustained pneumatic tooling demand
- Shops upgrading from 15HP or 20HP units that are short-cycling or pressure-dropping under load
- Facilities where floor space is at a premium and a vertical tank makes better use of available height
