Atlas Copco G15L-22 Rotary Screw Air Compressor Series

20-30HP Tri-Volt 3 Phase Rotary Screw Compressors: options with Integrated Dryer and Tanks

Atlas Copco G15L-22 Rotary Screw Air Compressor Series (20–30 HP)

If you need dependable shop air that can run all day without drama, the Atlas Copco G15L-22 rotary screw air compressor series is built for exactly that job. This is an oil-injected, belt-driven rotary screw platform designed for small-to-mid production environments that want quiet operation, continuous duty capability, and a compact footprint—without stepping up into a large industrial package.

Built for real work shifts (not short bursts)

The G15L-22 series is engineered for continuous demand with 100% continuous duty cycle capability and reliable operation in hot mechanical rooms—rated for ambient temperatures up to 46°C / 115°F. This series is also positioned as a “workplace” compressor with sound levels that stay practical for many shops, typically around 67–70 dB(A) depending on configuration.

Quick specs at a glance

You’ll see the G15L-22 series offered in three power sizes:

• G 15L: 15 kW / 20 hp
• G 18: 18 kW / 25 hp
• G 22: 22 kW / 30 hp

Typical capacity range (FAD) across the series spans roughly 66 to 131 cfm depending on model and pressure. Common pressure offerings include 7.5 / 10 / 13 bar(e) (50 Hz), with 60 Hz variants commonly listed from 100 to 175 psi depending on model.

Quiet, efficient belt-driven design

A big part of what makes this series attractive is the belt-driven element, designed to keep vibration and noise down while delivering steady airflow. Add the sound-insulated canopy, and the result is a rotary screw compressor that can often be installed closer to the work area—without automatically requiring a dedicated compressor room in many facilities.

Premium connectivity with Elektronikon® Nano™ + SMARTLINK

Many G15L-22 configurations are centered around Atlas Copco’s Elektronikon Nano control platform with SMARTLINK connectivity, giving you modern monitoring without buying a separate add-on system. With SMARTLINK, you can:

• Remote control (on/off, adjust pressure settings/bands, weekly schedule) via Bluetooth
• Monitor key performance (pressure, temperature, running hours, operating mode) and receive actionable summaries
• Get wireless feature updates for secure download—so the compressor can “get better over time”
• Use intelligent control logic like Delayed Second Stop (DSS) to reduce wasted run time during unloaded operation

SMARTLINK-based leak detection is also promoted as a way to help identify compressed air losses before they quietly inflate your power bill.

Pack vs. Full Feature: same compressor, different level of “air system built-in”

The G15L-22 series is typically available in two main build styles:

1. Pack (base compressor)
   A compact rotary screw package offered floor-mounted or tank-mounted, typically without an integrated dryer.
2. Full Feature (integrated dryer + filtration options)
   Full Feature versions include a built-in refrigerant dryer, plus the ability to configure in-line filtration depending on your air quality requirements. On Full Feature models, the integrated dryer is commonly specified around a 37°F / 3°C pressure dew point under rated conditions—helping reduce moisture-related rust and tool damage across the air network.

Built for uptime and straightforward service

This series is designed around practical reliability features that matter in real shops:

• A modern rotary screw compression element built for steady output
• An IP55 TEFC motor commonly specified to meet premium efficiency expectations
• A multi-stage air/oil separation system designed to help reduce oil carryover and oil consumption
• Continuous oil cleaning with filtration designed to protect bearings, rotors, and internal surfaces

For maintenance planning, Atlas Copco documentation and vendor listings commonly reference long service intervals (often up to 4,000 hours depending on operating conditions and maintenance practices), helping reduce interruptions and keep cost of ownership predictable.

Installation-friendly footprint (floor or tank mounted)

Shops love this series because it’s designed to be easy to place: compact footprint, and cooling/airflow design intended to support installation along a wall in a compressor corner or mechanical space.

Typical configuration options include:

• Floor-mounted (FM) standard or Full Feature
• Tank-mounted (TM) options, including larger receiver configurations for better storage and smoother cycling

Where the G15L-22 series fits best

This is a strong match for operations that need steady air for:

• CNC and light manufacturing
• Automotive repair and body shops
• Packaging and general production
• Woodworking and fabrication
• Any shop that values quiet rotary screw performance + compact installation

Popular options worth calling out

Depending on configuration and region, commonly listed options include:

• Automatic/electronic water drains
• Tropical thermostat (for hotter environments)
• Food-grade oil options for sensitive applications (when required)
• Synthetic oil options for extended performance in demanding duty cycles

Why buy the G15L-22 series

If you want a compressor that’s easy to live with, the G15L-22 lineup hits the sweet spot:

1. Continuous-duty rotary screw performance for real shop demand
2. Quiet operation that won’t dominate the workspace
3. Smart monitoring and control with Nano + SMARTLINK
4. Pack or Full Feature choices to match your air quality needs
5. Compact, installation-friendly design with multiple mounting configurations
