The Cast Air R10112VP75 is a 10 HP single-phase rotary screw air compressor with a 120-gallon vertical tank, rated at 40 CFM at 100 PSI. It is built for commercial shops, service garages, and fleet facilities that run on single-phase 230V power and need a continuous-duty air supply without the maintenance overhead of a piston compressor. The vertical tank orientation saves floor space while delivering the same large receiver volume as the horizontal configuration — the right trade-off for shops where square footage is at a premium but overhead clearance is available.
Key Features
- Rotary Screw Compressor Design: Oil-flooded rotary screw technology runs continuously without the heat buildup and pulsation of reciprocating piston compressors. Delivers steady air at consistent pressure across a full shift.
- Single-Phase Power: Operates on standard 230V single-phase electrical service. Shops without three-phase infrastructure can install this unit without electrical system upgrades or transformer costs.
- 40 CFM at 100 PSI: Rated free air delivery at 100 PSI working pressure. Covers the demand requirements of most general shop tools, lifts, and spray equipment running simultaneously.
- 120-Gallon Vertical Tank: Large receiver buffers demand peaks and reduces cycling frequency. The vertical orientation minimizes floor footprint while preserving full storage volume.
- Vertical Footprint Advantage: Uses less floor space than the horizontal 120-gallon configuration (R10112HP75), making it practical in tighter compressor rooms and utility areas with available ceiling height.
- Continuous Duty Rated: Rotary screw design is built for continuous operation across a full production day — not the 50-75% duty cycles typical of piston units at similar horsepower.

What This Compressor Handles
40 CFM at 100 PSI covers a wide range of production shop tasks:
- Pneumatic lifts and vehicle hoists — cycling multiple lifts on the same compressed air supply
- Impact wrenches and air-driven hand tools — sustained operation without pressure recovery delays between technicians
- Spray painting and HVLP finishing — consistent pressure delivery for quality finish work
- Tire mounting, inflation, and bead seating — high-burst tasks in tire shops and fleet service bays
- Multiple air drops — the 120-gallon receiver supports several technicians drawing air simultaneously without starving individual drops
- Pneumatic shop equipment — press brakes, door openers, clamps, and other facility equipment on the same supply line
Horizontal vs. Vertical Tank — Choosing the Right Layout
Both the R10112VP75 (vertical) and R10112HP75 (horizontal) deliver the same 10 HP / 40 CFM / 120-gallon capacity. The orientation decision comes down to your space:
- Vertical tank (this unit) — smaller floor footprint, taller profile. Best when you have limited floor space but available ceiling clearance. Slightly higher center of gravity, so placement stability matters more.
- Horizontal tank (R10112HP75) — more floor area consumed, lower profile. Better under low ceilings, easier to roll through doorways, more stable in high-traffic areas. The horizontal unit is also rated to 135 PSI vs. 100 PSI on this vertical model.
- Pressure difference matters: If your tools or application require pressure consistently above 100 PSI, the horizontal R10112HP75 (rated to 135 PSI) is the correct choice. For standard 90-100 PSI shop applications, the vertical unit covers it.
80-Gallon vs. 120-Gallon — When the Extra Tank Volume Pays Off
- 120-gallon tanks (this unit) buffer larger demand spikes and reduce cycling frequency — the right call for multi-technician shops, spray booths, or any environment where air demand is sustained rather than intermittent.
- 80-gallon units (R1018VP75 at $10,647.82) work well for single-technician or lighter-use shops where the smaller footprint is more important than extended buffer capacity. The compressor cycles more frequently, but the CFM output is identical.
