Atlas MPAF9P-120H — 7.5HP 120 Gallon Compressor with Plus Package
The 10HP class is the right compressor for a shop that's already big — but a two-bay repair shop, a tire shop, or a serious home-service operation doesn't need to buy its ceiling. The Atlas MPAF9P-120H is the honest step down: 7.5 horsepower at 1750 RPM on 220-volt single-phase (40-amp breaker), delivering 23 CFM at 90 PSI into a US-made 120-gallon tank.
It carries the full Plus Package — air-cooled aftercooler, automatic low-oil monitor/shut-off, automatic tank drain — plus a cast-iron V-cylinder two-stage pump with stainless reed valves, and it ships pre-filled with synthetic oil. This is the current generation of the 7.5HP line, with live manufacturer specs and a published warranty.
Who the Atlas MPAF9P-120H Is Built For
- Two-bay repair shops and tire shops — 23 CFM at 90 PSI covers impact wrenches, a tire machine, and a balancer without the pump running flat-out.
- Shops on single-phase power with a 40-amp circuit — this is the 120-gallon class that fits residential-adjacent panels where a 50-amp 10HP circuit won't go.
- Buyers who want the Plus Package standard — aftercooler, low-oil monitor/shut-off, and auto tank drain are factory equipment, and it ships with synthetic oil already in the pump.
- Buyers comparing the old-generation AF9 Plus — the MPAF9P-120H is the current 7.5HP line with live specs and a published warranty; the AF9 Plus (also in stock) is the earlier generation with different CFM ratings.
- Shops that want pump longevity — cast-iron V-cylinder two-stage pump, aluminum head, machined valve plate, stainless reed valves: the construction that survives daily cycling.
What the Atlas MPAF9P-120H Is NOT Built For
This is not for high-demand body shops or multi-bay operations — 23 CFM is a two-bay number, and starving a bigger shop means the pump never rests (see the AF10 class). It's not for hobbyists either; a 60-gallon single-stage covers the weekend shop at a fraction of the price.
Important sizing note: confirm the 220V single-phase 40-amp circuit, measure the floor (72" × 32" footprint, 52" tall), and tally continuous CFM demand before purchase. Questions on fit? Call (817) 865-3707 before ordering — we confirm compatibility, not guesses.
What Makes the Atlas MPAF9P-120H Different
7.5HP on a 40-amp circuit
23 CFM at 90 PSI / 22 at 175, on 220V single-phase with a 40-amp breaker — the 120-gallon class for panels that can't feed 50 amps.

- 220V 1-phase, 40A breaker
- 23 CFM @ 90 / 22 @ 175 PSI

Built to cycle daily
Cast-iron V-cylinder two-stage pump, aluminum head, machined cast-iron valve plate, stainless reed valves — pump internals that survive a working shop's rhythm.
Best For
- Two-bay repair / tire shops
- Single-phase 40A panels
- Plus Package standard
- Current-generation 7.5HP
Not Ideal For
- High-demand multi-bay shops (see AF10)
- Hobbyists (see AF3/AF4)
- 3-phase shops
Air Force line — the 7.5HP position
| Model | Motor | Delivered Air | Breaker |
|---|---|---|---|
| MPAF9P-120H (this page) | 7.5 HP @ 1750 RPM | 23 CFM @ 90 / 22 @ 175 | 40A 1-Phase |
| AF10 Plus 1PH | 10 HP low RPM | 37 CFM @ 90 / 35 @ 175 | 50A 1-Phase |
| AF-15 Plus | 15 HP | 52 CFM @ 100 / 49 @ 175 | 3-Phase |
The CFM gap between 23 and 37 is the real decision — count your air tools honestly before choosing the 10HP class.
