G7L-15 Series Rotary Screw Air Compressor By Atlas Copco

10-20HP Rotary Screw Compressors: options with Integrated Dryer and Tanks. All Models Tri-Volt (208-230/460) 3 Phase.

Atlas Copco G7L-15 Rotary Screw Air Compressor Series (7–15 kW)

When you need dependable plant or shop air without the noise, heat, and constant babysitting of a piston compressor, the Atlas Copco G7L-15 series delivers true rotary-screw performance in a compact, work-ready package. These oil-injected rotary screw air compressors are built for everyday industrial and professional use—designed to run hard, stay quiet, and keep operating costs under control.

Available in 7 kW, 11 kW, and 15 kW variants, the G7L-15 platform is engineered to be an energy-efficient “workplace compressor” that helps minimize total cost of ownership—without sacrificing reliability in harsh environments.

Real rotary-screw output you can size with confidence

The G7L-15 family covers a practical range of air demands, with flow capability spanning roughly 29–70 cfm depending on model and pressure.

Typical free air delivery (FAD) at 100 psig (reference conditions) is:

• G7L: ~45 cfm
• G11: ~61 cfm
• G15: ~69 cfm

Need higher pressure? The series supports higher-pressure configurations up to the 175 psig class (model/variant dependent). At ~174 psig, reference-condition FAD is shown as ~29 / 40 / 49 cfm for G7L / G11 / G15.

Choose your configuration: Pack or Full Feature

Atlas Copco offers the G7L-15 series as:

• Pack (stand-alone compressor)
• Full Feature (integrated refrigerated dryer)

For customers who want cleaner, drier air right out of the cabinet, Full Feature models integrate drying to protect downstream tools, controls, and finished products. The integrated dryer is rated to deliver a pressure dew point around 3°C / 37°F at maximum FAD (at 100% RH, 20°C/68°F conditions).

If you choose a Full Feature tank-mounted unit, Atlas Copco also uses a “dry tank” concept (the dried air is stored in the receiver), which helps extend receiver life by reducing internal moisture exposure.

Quiet operation that fits the workplace

Rotary screw performance doesn’t have to mean a dedicated compressor room. With a sound-insulated enclosure, the G7L-15 series is built to stay comfortable in real working environments, with published sound levels in the ~67–71 dB(A) range (model dependent).

The platform is also designed for high-heat conditions, with standard operating capability up to 46°C / 115°F ambient.

Built-in reliability where it matters

This series is constructed around core components that keep uptime high and maintenance predictable:

• State-of-the-art compression element
• IP55 (TEFC) motor meeting or exceeding NEMA Premium / IEEE efficiency expectations
• High-efficiency two-step air/oil separation system for reduced oil carryover and lower operating costs
• Continuous oil filtration designed to remove fine particles and help protect rotating components

For applications that require clean air downstream, typical oil content is shown around 2 ppm (application/condition dependent), and additional filtration can be applied as needed.

Smarter control and mobile-ready connectivity

Every G7L-15 is built around an icon-based Nano Elektronikon controller that supports practical, day-to-day visibility:

• Running hours and loaded hours counters
• Service warnings
• Pressure and element outlet temperature readouts

On connected versions, the controller is designed as an IoT-ready platform and works with SMARTLINK for monitoring and control. Through the app you can view real-time operating data, receive push notifications for warnings/shutdowns, and remotely manage key functions like start/stop, pressure settings, and weekly schedules.

Connectivity options commonly include Bluetooth for local pairing plus Wi-Fi or Ethernet for cloud connection, and the platform supports over-the-air firmware updates when connected.

Designed to keep ownership costs predictable

Maintenance is straightforward and interval-based, with a documented preventive schedule (your local conditions may adjust intervals). Examples include major service actions such as oil filter, air filter, and separator replacement at 4,000 hours under standard conditions.

Common applications for the G7L-15 series

• General manufacturing air and workstation drops
• Automotive and fleet maintenance shops
• CNC support air, packaging lines, and maintenance air
• Light industrial facilities needing quiet, continuous-duty compressed air

What you get with the Atlas Copco G7L-15 platform

1. A compact oil-injected rotary screw compressor built for continuous-duty workplace use
2. Choice of Pack or Full Feature (integrated dryer) configurations
3. Quiet, enclosed design for near-point-of-use installation
4. Modern control, service visibility, and app-connected monitoring options

If you want a reliable rotary screw air compressor that’s sized for real shop demand—without wasting floor space or wrecking your sound environment—the Atlas Copco G7L-15 series is the clean, professional upgrade that pays off in uptime, efficiency, and day-to-day usability.
