Atlas Copco GA30+-GA37 Rotary Screw Air Compressor Series

Atlas Copco GA30+ and GA37 Oil-Injected Rotary Screw Air Compressor Series (Pack + Full Feature)

Looking for a GA45 or larger? The 60 to 125 HP machines now have their own page: see the Atlas Copco GA45-GA90 Rotary Screw Air Compressor Series, which covers GA45, GA55, GA75 and GA90 in Pack and Full Feature, air-cooled and water-cooled.

When you need dependable plant air in the 30-37 kW (40-50 HP) class, the Atlas Copco GA30+-45+ platform is built to deliver steady performance, quieter operation, and smarter control in a compact package. These oil-injected rotary screw air compressors pair a gear-driven rotary screw element with an integrated lubrication and cooling system inside a sound-insulated enclosure, so you can reduce noise at the source and keep installation clean and efficient.

This series is designed around real-world uptime: robust filtration, simplified service access, remote monitoring, and options like an integrated dryer (Full Feature) and energy recovery to match how your shop or facility actually runs.

Why the GA30+ platform is a set it and run it compressor

Atlas Copco's design focus here is straightforward: lower total cost of ownership, quiet workplace-friendly packaging, and reduced downtime to service.

• High-efficiency motor and updated compression element, targeting improved air delivery and energy efficiency versus prior designs
• Maintenance-friendly drivetrain layout and quick-change service components to shorten routine maintenance time
• Oversized coolers with integrated water separation and a quiet, modern fan design for stable temperatures and reduced sound levels

Quiet, compact, and ready for work-floor installation

A major advantage of this series is how easy it is to live with day-to-day. The acoustical sound-attenuating enclosure and integrated package design allow placement closer to point-of-use, helping minimize piping runs and avoid building a separate compressor room in many layouts. The platform is also engineered to be space-conscious, making it easier to fit into tight mechanical rooms and production spaces.

Smart control and remote monitoring built in

Control and visibility matter just as much as horsepower. This series supports modern onboard control plus remote monitoring for better uptime and maintenance planning.

• Elektronikon Touch control (standard on some configurations, optional upgrade on others)
• Swipe-style controller options depending on exact model and configuration
• SMARTLINK remote monitoring, enabling status checks, service reminders, and performance trend tracking from a connected device

Built-in protection for long life and cleaner air

This is where the platform earns its reputation in industrial environments: strong filtration and separation that protect the element and your downstream equipment.

• High-efficiency inlet filtration to reduce particulate ingestion and extend component life
• Oil filtration plus an ASME air/oil separation system designed for consistent separation performance
• Air-cooled aftercooler to reduce discharge temperatures and help manage moisture
• Designed to handle hot shop conditions, with high ambient capability depending on configuration

Pack vs. Full Feature: choose your factory-integrated configuration

You are still buying the same compressor platform. These are two popular ways it is packaged.

Pack (Base Mount)

A complete compressor package with aftercooler, enclosure, and controls, optimized for straightforward installation, dependable operation, and easy service access.

Full Feature

Everything included in the Pack configuration plus an integrated refrigerant dryer inside the same sound-insulated package. Ideal when you want dryer-quality air without dedicating extra floor space to a separate dryer.

Options that let you build the exact system you want

Efficiency and heat management

• Energy Recovery option, capturing compressor heat and redirecting it to water for facility use
• High ambient configuration options for hotter environments
• Heat-management accessories such as thermostat and ducting-related options depending on layout

Air quality and protection

• Prefilter options for harsher environments
• Rain protection for certain installation conditions
• Filtration add-ons when the application requires cleaner air downstream
• Food-grade oil option for facilities that prefer it for policy or application alignment

Controls and multi-compressor management

• Controller upgrades and add-on control modules depending on the chosen base controller
• Central control options to coordinate multiple compressors, helping stabilize pressure, balance run hours, and reduce wasted unloaded time in multi-unit systems

Installation-friendly details your team will appreciate

1. Factory-packaged design keeps the footprint and piping complexity lower than piecing together separate components.
2. Service access layout is designed to reduce time on common tasks like filters and fluid changes.
3. Energy recovery-ready plumbing connections are available when that option is selected.
4. The platform supports common industrial voltages and pressures depending on the specific model build.

Where this series fits best

• Automotive and general manufacturing
• Fabrication and machine shops
• Packaging, maintenance facilities, and utility rooms where footprint and sound level matter
• Plants looking to standardize on a service-friendly compressor platform across multiple bays
