G11 - 15Hp Rotary Screw Air compressor with Dryer, 120 gal air tank - 208-230/460/3/60 - 125 PSI

The Atlas Copco G11 FF (8153290864) is a receiver-mounted, oil-injected rotary screw air compressor with a built-in refrigerant dryer, delivering 52.8 cfm (24.9 l/s) of compressed air at 125 psi (8.6 bar). Oil-injected means a small amount of compressor oil is fed into the screw element during compression to seal, cool, and lubricate it, giving smooth, continuous output. The "FF" stands for Full Feature, which is our term for a package that adds an integrated dryer: a compressed air dryer that chills the air to around 43 °F (6 °C) so moisture condenses out and drains away, leaving dry air at the outlet ready to feed tools, piping, and pneumatic equipment without the water problems that untreated air causes downstream.

Everything sits on a 120-US-gallon (454-liter) air receiver, so the compressor, dryer, and tank arrive and are installed as a single tank-mounted package. That makes it a practical screw air compressor for a busy workshop or workplace where a steady, moderate flow is needed all day. The 15 hp (11 kW) IE3 motor is a high-efficiency, totally enclosed type, and the unit is rated for 100 percent duty at ambient temperatures up to 115 °F (46 °C), so it can run continuously in warm rooms without needing to stop and cool down.

Air delivery is regulated by load/no-load control managed by the Elektronikon Basic microprocessor controller, which automatically switches between compressing and idling to match demand and hold pressure without wasting energy during quiet periods. The screw element is lubricated by a long-life Roto-Xtend Duty synthetic compressor oil, with a charge of about 0.85 US gallons (3.2 liters).

To help with sizing and installation, the unit is supplied for a 208-230/460 V, three-phase, 60 Hz supply, and carries UL/cUL electrical approval and ASME mechanical approval, which matters for North American installations. It is built in Italy. Rated performance holds up to 3281 feet (1000 m) above sea level, above which output derates, so allow for that at high-altitude sites.

Before ordering, confirm that the supply voltage on site matches the 208-230/460 V, three-phase, 60 Hz rating and that your outlet piping and condensate drainage are ready for a tank-mounted unit of this size.
