Atlas® AF9-120H 7.5HP 120 Gallon Horizontal Air Compressor #ATEMPAF9-120H

Atlas® AF9-120H — 7.5 HP, 1750 RPM Air Compressor

Horizontal tank space is often the deciding factor over vertical in shops with low ceiling clearance or equipment already mounted along the walls — the tradeoff only works if the horizontal unit still delivers commercial-grade CFM.

The Atlas® AF9-120H is a commercial 2-stage reciprocating compressor rated for 7.5 HP, 1750 RPM with a 120 gallon horizontal tank, built for shops and commercial operations that need compressed air on tap all day without paying for accessories they don’t need.

Who the AF9-120H Is Built For

• ✅ Large automotive shops and industrial facilities running multiple technicians off compressed air throughout the business day
• ✅ Shops that need the extended runtime a 120-gallon tank provides — less compressor cycling, longer intervals between motor starts
• ✅ Operations running paint work, sandblasting, and heavy pneumatic tool use simultaneously where 22 CFM at 175 PSI keeps every bay supplied
• ✅ Facilities with the floor space for a horizontal tank layout, which distributes weight differently than a vertical tank of similar capacity
• ✅ Shops that depend on compressed air every business day and want the durability of industrial-grade Hubbell/Eaton electrical components
• ✅ Buyers upgrading from an 80-gallon 7.5HP unit who need more storage capacity without stepping up to 3-phase power

What the AF9-120H Is NOT Built For

• ❌ Shops tight on floor space — the 72" L × 32" W horizontal footprint needs considerably more room than an 80-gallon vertical tank of the same HP
• ❌ Smaller operations that don't need 120 gallons of storage — the standard 80-gallon AF9 or AF9P covers most multi-bay shops for less money and less floor space
• ❌ Facilities with 3-phase power available — the AF10 3-phase model offers smoother operation and greater efficiency for that electrical setup

What Makes the AF9-120H Different

Commercial 2-Stage Pump

The AF9-120H uses a 2-Cylinder, 2-Stage Cast Iron pump built for daily, all-day duty cycles — not a hobby-grade single-stage unit that struggles under continuous shop use.

CFM & Pressure Output

Delivers 23 CFM @ 90 PSI and holds pressure across a 145–175 PSI range, enough headroom to run impact wrenches, tire equipment, and paint tools without the tank running dry.

Plus Package Upgrades

standard configuration; Hubbell pressure switch and Eaton starter included.

Power Requirements

220V, 1-Phase, 40 Amp Breaker, #8 Wire Required. Confirm your panel and breaker sizing with an electrician before delivery.
