Atlas Air Force AF8P Air Compressor

Description

The Atlas Air Force AF8P is a commercial-grade 5 HP two-stage air compressor built around an 80-gallon vertical steel tank made in the USA. The 2-cylinder, 2-stage pump delivers 20 CFM at 145 PSI and 19 CFM at 175 PSI, which is enough headroom to run multiple pneumatic tools at the same time in a 3-to-4-bay shop or to leave room to grow if you are working solo today.

What separates the AF8P from the base AF8 is the factory-installed Plus Package: an automatic low-oil monitor that shuts the unit down before a dry pump destroys itself, an automatic tank drain that purges condensate without a manual valve, and an air-cooled aftercooler that drops discharge-air temperature so less moisture reaches your tools and lines. Those three upgrades extend pump life and produce cleaner, drier air, which is the difference between a compressor that costs you a service call every quarter and one that runs in the background.

Electrical service is 220V single-phase on a 30 amp breaker with #10 wire, which most small commercial shops already have. The factory pairs a Hubbell industrial-grade pressure switch with an EATON magnetic starter, so the contactor and inrush protection are name-brand parts your local electrician can service. Vibro-isolation pads, a heavy-duty metal belt guard, a finned tank inlet tube that reduces internal moisture, and a hands-free tank drain extension all come standard.

Features

• 2-cylinder, 2-stage pump rated for commercial duty cycles
• 5.0 HP, 1750 RPM heavy-duty motor running on 220V single-phase
• 80-gallon vertical steel tank, made in the USA
• 20 CFM at 145 PSI / 19 CFM at 175 PSI, 145–175 PSI working range
• 3/4" NPT air outlet sized for shop drops and main runs
• Plus Package: automatic low-oil monitor, automatic tank drain, air-cooled aftercooler
• EATON magnetic starter for controlled motor inrush and longer motor life
• Hubbell industrial-grade pressure switch
• Compressor oil drain extension tube for easier service intervals
• Hands-free tank drain extension
• Finned tank inlet tube to reduce moisture accumulation inside the tank
• Heavy-duty metal belt guard
• Vibro-isolation pads included
• Built for daily commercial use in 3–4 man shops or solo shops planning for growth

The air-cooled aftercooler shown above is part of the Plus Package. It drops air temperature on the way from the pump to the tank, which condenses moisture out of the air stream before it accumulates in the tank — drier air at the outlet, less water inside the tank, and longer life on the tools downstream.

The automatic low-oil monitor watches pump oil level and shuts the unit down before low-oil damage starts — a fail-safe that pays for itself the first time a busy bay forgets a service interval.

FAQ

Is 20 CFM at 145 PSI enough to run multiple shop tools at once?

For most 3-to-4-bay shops, yes. A 1/2" impact wrench typically draws 4–5 CFM at 90 PSI intermittent, a die grinder 5–8 CFM continuous, and a HVLP paint gun 9–13 CFM continuous. With 20 CFM available at 145 PSI tank pressure and an 80-gallon reservoir, the AF8P can run two-to-three intermittent tools simultaneously and recovers quickly. High-continuous-draw tools like media blasters and large sanders may want a higher-CFM compressor.

Is this single-phase or three-phase?

Single-phase. The AF8P runs on 220V single-phase service, 30 amp breaker, #10 wire. No three-phase service required. The factory-mounted EATON magnetic starter handles motor inrush, so you do not need a separate motor starter.

What exactly is the Plus Package?

The Plus Package adds three factory-installed items over the base AF8: an automatic low-oil monitor (shuts the unit down before a dry pump damages itself), an automatic tank drain (purges condensate automatically without a manual valve at the bottom of the tank), and an air-cooled aftercooler (reduces discharge-air temperature so less moisture carries to your tools and lines).

How loud is the AF8P?

Atlas describes the AF8P as “extremely quiet operation.” The low-RPM motor (1750 RPM), 2-stage pump, vibro-isolation pads, and heavy-duty metal belt guard all reduce operating noise compared to a higher-RPM single-stage compressor of similar capacity. Atlas does not publish a decibel rating for this model.

Does it need a special concrete pad?

The AF8P is a vertical tank unit with vibro-isolation pads included. Place it on a level shop floor — no special pad required. Bolt-down anchors are optional depending on local code.

Will the AF8P fit through a standard shop door?

The compressor is 40" long × 24" wide × 71" tall and ships at approximately 605 lb. Most commercial shop doors accommodate the 24" width comfortably. Measure your delivery path before order.

What is the warranty?

1-year parts-only warranty. Atlas covers replacement parts during the warranty period; labor and freight on warranty parts are owner responsibility.
