The Castair R10312VP75-460 is a 10 HP, 3-phase rotary screw air compressor rated at 40 CFM at 100 PSI, configured for 460V three-phase power and mounted on a 120-gallon vertical tank. This is the highest-voltage, vertical-format unit in the Cast Air 10 HP rotary screw lineup — the right choice for industrial and commercial facilities with 460V (or 480V) three-phase service where floor space is limited and ceiling height is available. At 1,830.12, this is a capital equipment purchase built for production shift operation, not occasional use. The 460V configuration specifically targets heavy industrial environments, auto dealerships with modern electrical infrastructure, large fleet facilities, and any shop where a licensed electrician has confirmed 460V service at the panel.

Key Features
- 40 CFM at 100 PSI: Confirmed free air delivery at rated working pressure. This is the number that determines what your shop can run simultaneously. At 40 CFM, you have enough air for multiple heavy-demand tools — two spray guns, several impact wrenches, air-operated lifts, tire service equipment — running at the same time without pressure sag at the tool.
- 460V three-phase motor: Higher voltage means lower current draw at the same wattage. A 10 HP motor at 460V three-phase draws approximately half the amperage of the same motor at 230V. That means smaller wire gauge required, smaller breaker, less heat in long conduit runs, and lower resistive losses in the wiring. For a facility with existing 460V service, this is the electrically correct choice.
- Rotary screw compression element: Continuous duty. No heat-related shutdowns. No duty cycle limit. The screw element runs as long as your shop runs, maintaining consistent output pressure without the thermal buildup that limits piston compressors in high-demand applications.
- 120-gallon vertical receiver tank: Upright orientation reduces floor footprint compared to a horizontal tank of the same capacity. The 120-gallon buffer is large enough to absorb demand spikes from multiple tools starting simultaneously, keeping line pressure stable at every drop in a multi-bay installation.
- Oil-flooded screw compression stage: Oil-flooded operation keeps the compression element cool during continuous-duty runs and provides internal lubrication that extends element service intervals. An integrated oil separator removes oil from the compressed air stream before it reaches your equipment and lines.
- Built for industrial environments: Cast Air manufactures in the United States. These machines are built to the load and environmental expectations of real shop and industrial use — not the gentler duty cycles of light commercial applications.

What 40 CFM at 100 PSI Supports in a Production Environment
Understanding the CFM number is how you know whether this compressor is the right size before you install it. Real-world demand in a shop or industrial bay:
- 1/2-inch impact wrenches: 4-5 CFM each at operating pressure. The R10312VP75-460 supports six to eight running at the same time, with the rotary screw element continuously replenishing the receiver.
- HVLP spray guns: 10-15 CFM per gun. Two spray guns active simultaneously is well within the 40 CFM rating, making this a direct match for a busy refinishing booth or detailing operation.
- Air-over-hydraulic lifts: Shop lifts cycle significant CFM when raising or lowering. A large receiver and continuous-duty screw element handle lift cycling without measurable pressure drops at other tools on the same system.
- Sandblasting and abrasive blasting: Portable blast cabinets and pressure pot systems consume 10-25 CFM depending on nozzle diameter and operating pressure. The 40 CFM rating accommodates one active blast setup while other tools remain available on the same system.
- Multi-bay shop air distribution: In a ring-main or branch-drop piped system, the R10312VP75-460 serves as the supply for a modest multi-bay layout — four to six bays with moderate simultaneous use — without pressure drop at the far end of the system.
460V vs. 230V — Why Voltage Matters More Than You Might Think
The R10312VP75-460 and the R10312VP75-230 deliver identical 40 CFM output at 100 PSI. Performance is the same. The difference is entirely electrical, and it has real-world consequences for your installation cost and long-term operating efficiency.
At 460V, a 10 HP three-phase motor draws approximately 14-15 amps. At 230V, the same motor draws 28-30 amps. For a new electrical run from your panel to the compressor location, lower amperage means smaller wire gauge — a meaningful cost saving on a 50-foot or 100-foot conduit run. It also means the breaker is smaller and the wiring runs cooler over time.
The 460V version costs 1,830.12 versus call-for-pricing on the 230V model (R10312VP75-230). Call 866-217-0063 to compare both options with current pricing before you decide. Do not let a 00-600 price difference drive you to the wrong voltage for your facility — the wiring cost difference can easily exceed the price difference on a new installation.
Important: Do not attempt to run a 460V motor on 230V service or vice versa. Verify your panel voltage with a licensed electrician before ordering. The motor is wound for a specific voltage and is not field-configurable between 230V and 460V on this model. If you need dual-voltage flexibility, the R10312HP75-460 (horizontal tank) is wound for 230-460V dual configuration.
Vertical Tank — Why This Configuration
The vertical tank on the R10312VP75-460 is the right choice when floor area is the constraint and ceiling clearance is available. A 120-gallon vertical tank stands taller than its horizontal equivalent — confirm ceiling clearance in your compressor room or installation bay before ordering. In exchange for the height, you recover floor space that a horizontal tank of the same capacity would occupy.
If your installation space has a low ceiling but adequate floor area, the horizontal-tank equivalent (R10312HP75-460) is a better fit. Both machines deliver the same 40 CFM at 100 PSI. The orientation choice is purely about your room geometry.
