Atlas Copco GA22-37VSD Variable Speed Rotary Screw Air Compressor

30-50HP Variable Speed Rotary Screw Compressor with Integrated Dryer options

Atlas Copco GA22-37 VSD Rotary Screw Air Compressor Series (GA 22 VSD / GA 26 VSD / GA 30 VSD / GA 37 VSD)

If you want premium compressed air without paying premium energy bills, the Atlas Copco GA22-37 VSD series is built for exactly that. These oil-injected rotary screw compressors with Variable Speed Drive (VSD) continuously match motor speed to your real air demand—so you avoid the waste that comes from running full speed when your plant isn’t actually using full flow. The result is a compact, modern compressor package designed for serious uptime, lower operating cost, and smarter control.

Powerful VSD savings that show up on the utility bill

Energy is typically the largest lifetime cost of a compressor. The GA22-37 VSD tackles that head-on with a drive train engineered for efficiency and strong part-load performance.

Efficiency highlights:

• Up to 50% energy savings compared to fixed-speed GA models (application dependent)
• Ferrite-Assisted Synchronous Reluctance (FASR) motor designed to meet IE5-equivalent efficiency levels
• Up to 80% heat recovery available as an option, capturing waste heat for space or process heating
• SMARTLINK connectivity support to help track performance and reduce energy waste over time

Designed for uptime in demanding industrial spaces

The GA22-37 VSD series is built to keep producing air through hot, dusty, and high-use environments, while simplifying the components that typically drive downtime.

Reliability advantages:

• IP66-protected drive train and a direct-drive design (no gears or belts), reducing maintenance points and losses
• Efficient internal separation and cooling flow that supports stable air delivery and long-term durability
• Designed for industrial operating environments and installations where consistent performance matters

Smart control, simple operation

Every GA22-37 VSD is built around Atlas Copco’s control ecosystem so operators and owners can stay ahead of service needs and monitor compressor status without babysitting the machine.

Controls and visibility:

• Elektronikon Touch controller for monitoring, warnings, shutdown protection, and maintenance scheduling
• SMARTLINK-ready capabilities for remote visibility, alerts, and optimization insights
• No-loss drain with alarm to protect air quality and avoid unnecessary air loss

Compact footprint with Full-Feature flexibility

A major reason shops choose this platform is how easily it fits into tight mechanical rooms, or closer to the point of use, without compromising performance.

Available configurations:

• Pack: compact, vertical canopy design
• Full Feature (FF): integrates dryer airflow into the system layout for simpler installs and built-in air treatment

Typical footprint (GA 22-37 VSD platform):

• Pack: compact cabinet footprint for space-conscious compressor rooms
• Full Feature: extended cabinet depth to accommodate integrated air treatment components

Performance snapshot

This is a true 22–37 kW (30–50 hp) VSD lineup with working pressures up to 13 bar(e) and wide turndown to track real demand.

At 7 bar(e), typical capacity ranges:

• GA 22 VSD: 27.7–158.3 cfm (22 kW / 30 hp)
• GA 26 VSD: 27.7–164.3 cfm (26 kW / 35 hp)
• GA 30 VSD: 27.7–206.4 cfm (30 kW / 40 hp)
• GA 37 VSD: 27.7–244.9 cfm (37 kW / 50 hp)

Noise levels:

• Approximately 68–71 dB(A), depending on model and configuration

Options to tailor the system to your plant

The GA22-37 VSD platform is easy to customize for air quality, uptime, and operating cost.

Common options include:

• Energy recovery
• Dryer bypass
• DD / UD+ filtration packages
• Heavy duty inlet filter or pre-filter options
• FoodGrade ultra oil options (application dependent)
• Roto Synthetic Xtend oil
• High ambient or tropical thermostat options
• Main switch and freeze protection options

Where the GA22-37 VSD series fits best

These compressors are a strong match for operations that want stable pressure, lower kWh consumption, and premium controls without adding complexity.

Typical applications:

1. Manufacturing and general industrial plants
2. Automotive shops, collision centers, and service bays
3. Packaging, machining, and production lines with fluctuating demand
4. Facilities upgrading from fixed-speed compressors to cut operating costs

Why customers choose the GA22-37 VSD series

• Cuts energy waste by matching output to demand
• Premium efficiency motor and drive architecture built for modern energy expectations
• Smart control and monitoring support for proactive maintenance
• Compact installation options, including integrated air treatment configurations
• Built for daily industrial use where uptime and total cost of ownership matter

The Atlas Copco GA22-37 VSD series delivers a high-efficiency, compact, connected rotary screw platform designed to reduce operating costs while keeping your facility supplied with dependable compressed air—without drifting into GA22-37 “VSDs” product information.
