Atlas Copco G2 - G7 Rotary Screw Air Compressor Series

Atlas Copco G 2–7 Rotary Screw Air Compressor Series (3–10 HP)

3–10HP Rotary Screw Compressors: options with Integrated Dryer and Tanks
Atlas Copco compressors are legendary for their reliability and efficiency. Our G series has long been the preferred air solution for small and medium-sized businesses. The G 2-7 VSD, the G 2-7, the G 7L-15, and the G 15L-22 simply check all the boxes. Whether you need a G5 air compressor, a G15L air compressor, or anything in between, we have you covered.

The Atlas Copco G 2–7 series is a compact, quiet, oil-injected rotary screw compressor lineup built for real-world shop use. Compared to piston compressors, these units are typically quieter, cleaner, and more economical, while handling longer run times with consistent airflow. With multiple configurations—Pack, Full Feature (integrated dryer), and tank-mounted options—you can match the compressor to your footprint, air quality needs, and daily workload.

Built in Reliability

Atlas Copco’s trusted rotary screw technology is engineered for steady, dependable performance you can count on every day. The G 2–7 series is designed for continuous operation and built with proven components that help reduce downtime and extend service life.

Key reliability advantages include:

• A robust rotary screw design suited for longer duty cycles than many piston compressors
• A complete package engineered to run in ambient temperatures up to 46°C / 115°F
• VSD models with gradual start-up to reduce stress on key components and lower starting current

If your shop depends on compressed air for production, fabrication, automotive work, or general maintenance, reliability isn’t optional—it’s the foundation of profitability.

Top Performance

The G 2–7 series delivers smooth, consistent compressed air with the efficiency rotary screw compressors are known for. These compressors are built to support real working environments where stable pressure and low noise matter.

Performance highlights:

• Quiet operation supported by a belt-driven design that helps keep vibration low
• Consistent airflow delivery for day-to-day tool and equipment demands
• G 2–7 VSD models that help maintain more stable pressure as demand changes

Full Feature versions add built-in air treatment in a compact package, which can help protect tools, improve process quality, and reduce moisture-related issues in air lines.

State of the art connectivity

Modern compressed air systems shouldn’t be a mystery. The G 2–7 series brings smarter control and monitoring so you can stay on top of performance, efficiency, and uptime.

Connectivity and control benefits include:

• Bluetooth-enabled monitoring on supported controls for convenient access
• Visibility into critical operating data like pressure, temperature, running hours, and operating mode
• Smart control features such as Delayed Second Stop to support efficiency and reliability
• Built-in tools like leakage detection to uncover wasted energy in your compressed air system
• Notifications that help you respond quickly and avoid surprise downtime

This kind of visibility is especially valuable for small businesses that can’t afford to lose a day of production because a compressor issue went unnoticed.

Easy Installation and Maintenance

The G 2–7 series is designed to fit where you need it and stay easy to own over the long haul. Its compact footprint and flexible configurations make it a strong choice for shops where space is limited and service time needs to stay minimal.

Installation and layout advantages:

• Available in multiple configurations, including floor-mounted or tank-mounted
• Options with or without an integrated refrigerant dryer to match your air quality requirements
• Compact footprint with airflow management that supports placement against a wall or in a corner

Maintenance-friendly design details:

• Key components are positioned for quick access during routine service
• Filters and separators are designed to be reachable without unnecessary disassembly
• Service tasks are streamlined to help reduce downtime and keep operating costs predictable

Robust and Efficient Compression Element

At the heart of every G 2–7 compressor is Atlas Copco’s proven rotary screw compression element—built to deliver strong free air delivery with dependable, long-term performance.

Why the compression element matters:

• Efficient air compression that helps reduce energy consumption over time
• Reliable design built for steady performance across long operating hours
• High-quality engineering that supports low total cost of ownership

Because the compression element is the core of the machine, a well-designed element is one of the biggest reasons rotary screw compressors outperform piston compressors in demanding, everyday use.

Configuration Options

The G 2–7 series is available in setups that let you choose the balance of footprint, air quality, and storage capacity that makes sense for your shop.

Common configuration choices include:

• Pack (no dryer): ideal when you already have air treatment or your application doesn’t require dry air
• Full Feature (integrated dryer): a compact all-in-one option to help reduce moisture in the air system
• Tank-mounted packages: combine compressor and receiver tank for a clean, integrated footprint

Ideal Applications

The Atlas Copco G 2–7 series is a strong fit for:

1. Automotive and light industrial shops running impact tools, blow guns, and tire equipment
2. Fabrication and welding environments needing reliable shop air all day
3. Woodworking and finishing setups where stable airflow supports consistent results
4. Small manufacturing operations looking to upgrade from piston compressors
5. Any workspace needing a quiet, compact compressor near the point of use

Why the Atlas Copco G 2–7 Series is a Smart Upgrade

If you’re moving up from a piston compressor—or replacing an older rotary screw unit—the G 2–7 series gives you the practical upgrades that matter most: quieter operation, efficient performance, flexible configurations, and modern monitoring.

You get:

• Rotary screw performance built for longer hours
• A compact footprint with multiple install options
• Integrated dryer and tank configurations for an all-in-one solution
• Smarter control tools that support efficiency and uptime

Choose the Atlas Copco G 2–7 Rotary Screw Air Compressor Series when you want a small-business compressor that’s engineered like industrial equipment—reliable, efficient, and ready to work.
