Atlas Air Force AF8 5HP 80-Gallon 2-Stage Air Compressor

5HP 80-Gallon 2-Stage Vertical Air Compressor — 20 CFM @ 145 PSI

A multi-bay shop runs on air. Lift jacks, impact guns, paint guns, spray systems, tire machines — they all draw simultaneously, and an undersized compressor cycles constantly, runs hot, and wears its pump out years before it should. Sizing the compressor to peak demand instead of average demand is the single biggest reliability decision in the air system.

The Atlas Air Force AF8 pairs a 5 HP industrial motor with a 2-cylinder, 2-stage pump and an 80-gallon vertical tank made in the USA. Delivered output is 20 CFM at 145 PSI (19 CFM at 175 PSI), with pressure setting from 145–175 PSI and a 3/4″ NPT air outlet sized for high-flow tools and full-bay distribution.

What’s Included

• Atlas Air Force AF8 5HP 80-gallon 2-stage compressor
• EATON magnetic starter (factory-installed)
• Hubbell industrial-grade pressure switch
• Set of vibro-isolation pads
• Hands-free tank drain extension
• Compressor oil drain extension tube
• Finned tank inlet tube for reduced water accumulation

Made For

Built for production shops that need real CFM at real pressure — sustained, not peak — across multiple bays.

• Independent multi-bay auto repair shops
• Body shops running spray guns and sanders
• Dealership service departments
• Fleet maintenance facilities
• Tire and wheel service shops running air-driven changers and inflators
• Industrial workshops with multiple pneumatic stations

Features

• 20 CFM at 145 PSI / 19 CFM at 175 PSI — sustained output for multi-bay tool draw
• 2-cylinder, 2-stage pump — efficient compression with lower head temperatures
• 80-gallon USA-made vertical tank — large reserve plus small floor footprint
• 5 HP motor on 220V / 30A single-phase — standard shop service, no 3-phase requirement
• EATON magnetic starter — industrial-grade motor protection for long service life
• Hubbell industrial pressure switch — durable cycling under heavy duty
• Hands-free tank drain + finned inlet tube — easier maintenance, less tank corrosion
• Vibro-isolation pads included — reduces transmitted vibration on shop floors

Why 2-Stage Compression Matters

Single-stage compressors compress air to working pressure in one piston stroke, which works fine at 90 PSI but runs head temperatures into the danger zone above 125 PSI. The AF8 is 2-stage — the first cylinder compresses air to about 90 PSI, then an intercooler cools it down before the second cylinder finishes compression to 175 PSI. The result is lower head temps, less oil carryover, and pump components that last materially longer in heavy duty cycles.

For shops running at the upper end of working pressure — spray booths, tire machines that need fast inflation, impact guns under load — that thermal headroom translates directly into the compressor’s expected service life.

USA-Made Tank with Industrial-Grade Switchgear

The 80-gallon vertical tank is manufactured in the USA and includes the finned inlet tube that drops incoming air temperature before it hits the tank — a meaningful reduction in condensed water and tank-bottom corrosion over the life of the unit. The hands-free drain extension routes the tank drain to a more accessible location for daily blow-down.

The electrical hardware on the AF8 is the part most shops first lose on a budget compressor. Atlas spec’d this unit with an EATON magnetic starter and a Hubbell pressure switch — the industrial brands you’d specify on a fixed-install machine, not the generic switches that come on a builder’s portable.

The Right Air Compressor for Your Shop

At 20 CFM at 145 PSI sustained, with a 5 HP 2-stage pump and an 80-gallon USA tank, the AF8 is sized for the actual draw of a busy multi-bay operation — not the marketing-spec horsepower number on a single-stage unit. The EATON/Hubbell switchgear is the difference between a compressor that runs for a decade and one that needs the starter replaced in year two.

The 3/4″ NPT outlet feeds a properly-sized distribution line into the shop, and the 220V/30A single-phase electrical means most shops can install it without a panel upgrade.
