Atlas® AF8 — 5 HP Heavy Duty, Low RPM Air Compressor
Multi-bay shops running impact wrenches, tire equipment, and paint guns off the same line need a pump that was actually built for that duty cycle — not a single-stage unit stretched past what it was designed to do.
The Atlas® AF8 is a commercial 2-stage reciprocating compressor rated for 5 HP Heavy Duty, Low RPM with an 80 gallon vertical 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 AF8 Is Built For
- ✅ Small businesses and 3–4 technician shops that need dependable, continuous daily air supply without paying for accessories they may not need yet
- ✅ Shops running pneumatic tools, tire machines, and sandblast cabinets at 145–175 PSI where consistent output matters more than moisture-control extras
- ✅ Buyers who want the industrial-grade pressure switch and magnetic starter Atlas builds into this tier, but don't need the Plus Package's automatic tank drain or aftercooler
- ✅ Operations upgrading from a 60-gallon single-stage unit to true commercial-grade 2-stage performance and 20 CFM output
- ✅ Shops that plan to handle tank draining and oil monitoring manually as part of routine maintenance rather than automating it
- ✅ Cost-conscious buyers comparing the AF8 against the AF8P who've decided the Plus Package upgrades aren't worth the added cost for their operation
What the AF8 Is NOT Built For
- ❌ Shops that want automatic tank drain and low-oil monitoring built in from day one to reduce maintenance oversight — see the AF8P
- ❌ Operations dealing with high humidity or moisture-sensitive air tools that would benefit from the AF8P's air-cooled aftercooler
- ❌ Shops needing more than 20 CFM continuous — look at the 7.5HP AF9 for higher-draw applications
What Makes the AF8 Different
Commercial 2-Stage Pump
The AF8 uses a 2-Cylinder, 2-Stage 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 20 CFM @ 145 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 AF8; add the aftercooler/auto-drain/low-oil monitor by stepping up to the AF8P.
Power Requirements
220V, 1-Phase, 30 Amp Breaker, #10 Wire Required. Confirm your panel and breaker sizing with an electrician before delivery.
- 3–4 technician commercial shops
- Daily continuous-duty air supply
- Buyers not needing Plus Package extras
- Shops wanting auto-drain/aftercooler built in — see AF8P
- Needs over 20 CFM — see AF9

| Pressure switch | Industrial-grade Hubbell + Eaton starter | Magnetic starter, manual tank drain, oil sight glass (standard simplex) |
