The Cast Air R1018HP75 is a 10 HP single-phase rotary screw air compressor with an 80-gallon horizontal tank, rated at 40 CFM at 100 PSI. It runs on standard 230V single-phase power — no three-phase electrical service required — making it the practical choice for shops, garages, and service facilities where the electrical infrastructure limits equipment options. The horizontal tank keeps the unit low-profile and stable, while the rotary screw design delivers continuous-duty performance that piston compressors at this horse power cannot match.
Key Features
- Rotary Screw Technology: Oil-flooded rotary screw design runs continuously, delivering steady, pulsation-free air. Unlike piston compressors, it does not cycle on and off under moderate load — it keeps pressure steady while tools are running.
- Single-Phase Operation: Runs on 230V single-phase service — the electrical supply available in the majority of commercial shops, dealerships, and light-industrial facilities in the U.S. No transformer upgrades or 3-phase panel work required.
- 40 CFM at 100 PSI: Rated free air delivery covers simultaneous use of impact wrenches, lifts, and spray equipment without starving individual air drops.
- 80-Gallon Horizontal Tank: Provides substantial receiver buffer while maintaining a low-profile footprint. The horizontal orientation is stable, easy to position, and fits under low ceiling clearances.
- Compact Footprint vs. 120-Gallon Configuration: The 80-gallon tank occupies less floor space than the 120-gallon models (R10112HP75 / R10112VP75), making it the right choice when shop layout is constrained.
- Continuous Duty Rated: Rotary screw compressors are designed for production-level continuous operation, not the intermittent duty cycles required of piston units.

What This Compressor Handles
At 40 CFM and 100 PSI, this unit covers standard production shop demand:
- Vehicle lifts and pneumatic hoists — reliable pressure for continuous lift cycling in service bays
- Impact wrenches, air ratchets, and hand tools — the rotary screw sustains pressure during extended tool use better than a piston unit of the same HP
- Spray painting and HVLP guns — steady pressure delivery without the spikes and drops that affect finish quality
- Tire service — inflation, bead seating, and deflation work in tire shops and fleet bays
- Multiple air drops — 80 gallons of receiver capacity supports multiple technicians working simultaneously, though peak demand may cycle the compressor more frequently than a 120-gallon unit would
- General shop pneumatics — shop presses, door operators, blow guns, and facility equipment
Horizontal Tank — Layout Trade-Offs
- Horizontal orientation (this unit) provides a lower center of gravity and better stability in high-traffic areas. It slides under overhead obstructions, rolls through standard doorways, and positions easily against walls. If your shop has low ceilings or limited vertical clearance, horizontal is the right call.
- Vertical alternative (R1018VP75 at $10,647.82) saves floor space at the cost of a taller profile. If you have available ceiling height and need to maximize usable floor area, the vertical version of this same 80-gallon unit is worth considering and comes in slightly lower in price.
80-Gallon vs. 120-Gallon — Choosing the Right Tank Size
- 80-gallon (this unit) is the right choice for shops with lighter simultaneous demand, single-technician operations, or constrained floor space. The compressor cycles more frequently under heavy demand, but the CFM output is identical to the 120-gallon models.
- 120-gallon tanks (R10112HP75 at $11,448.47 horizontal / R10112VP75 at $12,120.72 vertical) buffer larger demand spikes and cycle less often. For multi-technician shops or sustained high-demand work like spray booths, the larger tank is worth the additional cost and floor space.

Why Buy From OEM Diagnostic Tools?
We have been selling commercial shop equipment since 2016, and we are not a generalist catalog operation. We know what these compressors are used for, what questions shops run into during installation, and when a different configuration in the lineup is a better fit for your actual workflow.
- Free shipping on qualifying orders (freight delivery coordinated at time of sale)
- Free technical support — call 866-217-0063 before and after the purchase
- Full manufacturer warranty — we handle warranty claims and coordination on your behalf
- Honest size guidance — if the 120-gallon unit is what your shop actually needs, we will tell you upfront rather than selling you the unit that needs replacement sooner
