4 minutes

The new Atlas Copco G and GA Series rotary screw compressors deliver the same reliability with performance tailored to your needs. The G Series is ideal for workshops that value quiet operation, while the GA Series is built for continuous industrial use with maximum efficiency and durability. Let’s take a deeper look at how they compare.

Energy Efficiency and Savings

Both the G and GA Series are designed for reliable, efficient performance that helps lower energy costs over time. The rotary screw design minimizes wasted power and delivers consistent air output, while the new GA provides up to 10% more Free Air Delivery at no additional cost, giving you more productivity with the same investment.

What Makes the G and GA Series Different?

Both compressors use rotary screw technology for consistent air delivery, but they serve different roles.

  • G Series: Best for workshops that need quiet operation and reliable performance.
  • GA Series: Built for demanding industrial applications that run continuously.

Performance and Technology

  • G Series: Built for quiet, dependable performance with consistent air flow, low maintenance, and the low noise of rotary screw technology.
  • GA Series: Uses a vertically aligned gear-driven rotary screw for maximum output. Supports 100 percent duty cycles and includes advanced cooling for long life.

Reliability and Maintenance

  • G Series: Designed with easy service access and a sound enclosure for quieter work environments.
  • GA Series: Built for harsh environments with oversized cooling blocks, premium materials, and simplified maintenance points.

Industries and Applications

Atlas Copco’s G and GA compressors are engineered to meet the demands of a wide range of industries — from small local workshops to high-output production facilities. Each series brings unique strengths to different environments and workflows.

Workshops and Service Centers

Best Fit: G Series

Auto repair shops, tire centers, and maintenance garages rely on clean, consistent air for tools, lifts, and spray systems. The G Series’ quiet operation and compact design make it ideal for indoor workspaces where sound and footprint matter. Common uses include:

  • Powering pneumatic tools and impact wrenches
  • Spray painting and detailing
  • Tire inflation and cleaning stations

Manufacturing and Industrial Production

Best Fit: GA Series

Factories, assembly lines, and fabrication facilities depend on nonstop air supply. The GA Series provides reliable, 100% duty-cycle operation that keeps production moving around the clock. Typical applications include:

  • Running automation and robotic systems
  • Operating pneumatic actuators and conveyors
  • Supporting assembly, packaging, and material handling

Food and Beverage Processing

Best Fit: GA Series

Clean, dry compressed air is essential for packaging, bottling, and product handling. The GA’s advanced filtration and integrated drying ensure purity and performance that meet the strict demands of food-grade production. Common uses include:

  • Operating pneumatic packaging and labeling equipment
  • Powering bottle and can filling systems
  • Controlling valves and actuators on production lines
  • Air blowing and cleaning during product handling

Woodworking and Furniture Production

Best Fit: G or GA Series (depending on scale)

From small carpentry workshops to large-scale factories, these compressors power cutting, sanding, and finishing tools with steady, reliable air. The G keeps smaller shops quiet and efficient, while the GA supports high-volume production with minimal downtime.

Common uses include:

  • Powering sanders, planers, and nail guns
  • Running spray booths for painting and finishing
  • Removing sawdust and debris for a clean workspace
  • Driving CNC machines and automated cutting systems

General Industry and Utilities

Best Fit: GA Series

For facilities managing HVAC systems, maintenance fleets, or plant operations, the GA delivers long-term reliability and energy efficiency. It provides continuous compressed air for cleaning, cooling, testing, and equipment control. Common uses include:

  • Supplying control air for instrumentation and valves
  • Powering pneumatic tools for maintenance and repair
  • Cooling components and systems across production lines
  • Blowing off debris and contaminants from equipment

 Cost of Ownership

The GA Series now provides 10 percent more Free Air Delivery with no additional purchase cost. The G Series offers the same Atlas Copco quality at an accessible price point, giving you performance that pays off over time.

FAQ

How can these compressors help lower operating costs?
Both the G and GA Series are designed with efficiency in mind. The rotary screw design minimizes energy waste, and the updated GA provides up to 10% more Free Air Delivery at no extra cost. That means you get more usable air, more productivity, and lower costs over the compressor’s lifetime.
What is the primary difference between G and GA compressors?

The G and GA Series share the same Atlas Copco engineering quality but are built for different types of operations.

The G Series is ideal for workshops and light industrial environments where quiet, reliable performance is key. It delivers steady air flow through proven rotary screw technology in a compact, low-noise design.

The GA Series, on the other hand, is built for continuous industrial use. It’s engineered for higher Free Air Delivery, greater durability, and dependable operation in demanding conditions. With premium materials, efficient cooling, and advanced controls, the GA provides long-term reliability and performance you can count on around the clock.

My current air compressor system is unreliable and struggles to keep up with demand. How are the G and GA Series different?
 Atlas Copco’s G and GA Series compressors are designed for dependable, consistent performance. The G Series provides reliable rotary screw technology for everyday workshop use, while the GA Series delivers industrial-grade durability with higher Free Air Delivery and continuous operation capability. Both are built with quality components, simple maintenance access, and the proven reliability Atlas Copco is known for, so your operation runs smoothly without the downtime or pressure fluctuations that slow you down. 
What makes the GA Series a better choice for industrial applications?
 The GA Series is engineered for continuous, demanding environments. It delivers high Free Air Delivery for stronger, more consistent air output and is built with premium components for long-term reliability. Its direct-drive design and efficient cooling system help maintain steady performance, even in tough conditions. 
How does the G Series benefit smaller workshops or service centers?
 The G Series is ideal for workshops that need reliable air in a quieter, compact setup. It uses proven rotary screw technology to deliver steady air flow with less vibration and noise than piston compressors. Easy access to components also makes service and maintenance simple, saving you time and effort. 
How do I know which one is right for me?
 Choose the G Series for light industrial or workshop environments. Choose the GA Series for heavy-duty, continuous production needs.
