The Castair R30312HG30-230 is a 30HP 3-phase rotary screw air compressor with a 120-gallon horizontal tank, configured for 230V 3-phase service. At 30HP, this compressor moves into a tier where it can supply large multi-bay shops, production floors, and fleet maintenance facilities without becoming the air supply bottleneck during peak activity. The horizontal tank keeps the installation height low, making this the right choice for shops with limited overhead clearance in the compressor room or equipment bay.

Key Features
- 30HP Rotary Screw Element: Oil-injected rotary screw pump with 100% continuous duty rating — appropriate for facilities where the compressor never fully stops between shifts
- 3-Phase 230V Power Supply: Requires verified 3-phase 230V service with appropriate breaker and wire sizing for 30HP motor draw
- 120-Gallon Horizontal Tank: Low-profile configuration for ceiling-limited installations — same 120-gallon storage as the vertical model in a shorter, longer footprint
- Automatic Load/Unload Control: Intelligent controller extends pump life and reduces energy consumption by matching output to actual demand
- TEFC Motor: Totally Enclosed Fan Cooled motor for reliable operation in heavy-duty shop and industrial environments
- High-Efficiency Air/Oil Separator: Maintains low oil carryover levels to protect pneumatic tooling and air quality downstream
- Safety Controls and Pressure Relief: ASME-compliant safety equipment standard on all Cast Air tank-mounted units

Applications
30HP of rotary screw output handles operations that have outgrown the 20-25HP range. This unit is appropriate for:
- Large auto repair and collision shops with 8 or more bays running simultaneously
- Truck and heavy equipment service centers with high air demand from larger impact wrenches and air chisels
- Industrial production floors with multiple pneumatic stations running in parallel
- Body shops with continuous spray booth operation plus prep and finishing work happening at the same time
- Fleet maintenance facilities that need a primary compressor that will not limit crew productivity
- Facilities with low ceilings where the horizontal tank profile is a practical requirement
