What electrical service do I need to run the AF9P?
220 volts, single phase, on a dedicated 40-amp breaker, wired with #8 wire. The magnetic starter is included — there is no separate motor starter to purchase. Most shops on standard 220V single-phase service already have what they need; a fresh 40-amp circuit is typically the only electrical work required.
Is the AF9P quiet enough to run in a working bay?
Atlas describes the AF9P as extremely quiet for its class. The 1,740 RPM low-RPM motor and 2-stage pump design run noticeably quieter than higher-RPM single-stage compressors of similar output. The compressor still produces shop-level noise during the on-cycle; the vibro-isolation pads included with the unit reduce vibration transmitted to the floor.
What does the Plus Package do day to day?
Three things. The automatic low-oil monitor shuts the pump down before oil starvation damages bearings — a single missed oil check can otherwise end the pump. The automatic tank drain removes accumulated condensation without depending on the operator to remember a manual drain. The air-cooled aftercooler drops the air temperature before it reaches the tank, so moisture condenses out where it can be drained instead of being delivered to tools.
Why two-stage instead of single-stage?
Two-stage compression produces higher delivered pressure (175 PSI here) and runs cooler than a single-stage of comparable HP. For a shop running air tools, tire equipment, and lifts off the same circuit, the higher pressure and steadier operation translate into longer pump life and more consistent tool performance.
Is the tank really made in the USA?
Yes. Atlas specifies the 80-gallon vertical tank as made in the USA on the AF9P. The pump, motor, and electrical components are sourced separately and assembled into the complete unit.
