The Castair R10312VP75-230 is a 10 HP, 3-phase rotary screw air compressor mounted on a 120-gallon vertical tank and wired for 230V three-phase power. The vertical configuration is the distinction here: same 10 HP rotary screw performance as the horizontal sibling, but the tank stands upright to trade floor footprint for height. That trade-off makes the R10312VP75-230 the right call for shops, service bays, and mechanical rooms where floor space is the constraint — where every square foot counts and ceiling clearance is available. Three-phase 230V power is the most common commercial service voltage in North America, and this machine wires directly into existing service without a transformer upgrade.

Key Features
- Rotary screw compression: Unlike a piston compressor, the rotary screw element runs continuously without a duty cycle limit. No pauses to cool down. No pressure drop from an overheated pump. In a shop where tools run all day, that matters.
- Vertical 120-gallon receiver tank: Standing upright, the vertical tank reduces the floor area required compared to a horizontal configuration of the same capacity. The large receiver volume still provides an air buffer against demand spikes — multiple tools starting simultaneously will not crater line pressure.
- 3-phase 230V motor: Three-phase power delivers balanced load across three legs. Startup current is smoother, motor temperatures run lower, and the electrical draw is distributed more evenly than a single-phase motor of the same horsepower. 230V three-phase is standard in most commercial facilities.
- Continuous duty rated: This compressor is built for production environments. It handles all-day demand in a multi-bay shop, fleet maintenance facility, or contractor equipment yard without the heat-related limitations of a reciprocating unit.
- Oil-flooded compression stage: The rotary screw element runs oil-flooded for cooling and lubrication, keeping operating temperatures low and extending the service life of the compression element. Downstream separation removes oil before it reaches your air lines.

Applications — What This Compressor Handles
- Auto repair and body shop production bays: Multiple impact guns, air ratchets, and die grinders running simultaneously without pressure sag.
- Fleet maintenance facilities: Truck and heavy equipment shops that run lifts, air tools, and tire service equipment across multiple bays. The vertical footprint leaves more floor area for vehicle movement.
- Spray painting and refinishing: Continuous, stable air delivery to HVLP and conventional spray systems. Rotary screw output is consistent — no pump-recovery pauses that interrupt a spray pass.
- Sandblasting and abrasive work: High-demand operations that would quickly overheat a piston compressor run without constraint on a continuous-duty rotary screw machine.
- General pneumatic tools and shop air: Impact wrenches, grinders, drills, air hammers, and air-driven lifts — standard shop air demand for a production environment.
Vertical vs. Horizontal — Making the Right Choice
The R10312VP75-230 and its horizontal counterpart (R10312HP75-230) deliver identical compressor performance. The tank orientation is about your installation space, not about output. Choose vertical when:
- Floor space in your compressor room or bay is the primary constraint
- Ceiling height is adequate — a 120-gallon vertical tank stands taller than the horizontal configuration, so confirm clearance before ordering
- The compressor will be permanently anchored in place and not moved frequently
Choose horizontal when:
- Ceiling height is limited
- You need to move the unit periodically with a pallet jack
- The lower center of gravity and wider base of a horizontal unit better fits your space
Call us at 866-217-0063 before you order if you are unsure — we will ask about your space and point you to the right configuration.
230V — Is This the Right Voltage for Your Facility?
The 230V version of this compressor is the correct choice for facilities with standard 230V (or 208-240V) three-phase service. This covers the majority of commercial shops, auto dealers, fleet yards, and light industrial facilities in North America. If your facility runs 460V (or 480V) three-phase service, the R10312VP75-460 is the better fit — the same machine, wound for higher voltage, with lower current draw and smaller wire sizing requirements. Not sure what voltage your service panel provides? Call a licensed electrician before ordering — installing a 230V motor on a 460V circuit will destroy the motor on first start.
