What Are Atlas Copco Air Compressors? : 9 Important Series Explained
Choosing the wrong compressor series often leads to wasted investment, unstable air supply, or failure to meet air quality standards. Many users struggle to understand which Atlas Copco series truly fits their application.
Atlas Copco air compressors are organized into distinct series, each designed for specific power ranges, air quality levels, and industrial scenarios, covering everything from small workshops to large process plants.
Based on long-term experience with Atlas Copco systems across manufacturing, energy, and infrastructure projects, the following nine series are the most important to understand.
G Series
Small operations often outgrow piston compressors but do not need heavy industrial machines.
The G Series is Atlas Copco’s compact oil-injected screw compressor range for light industrial use.
The G series covers 5.5 naar 90 kW. Typical models include G7 VSD and G15–22 VSD, with optional built-in refrigerated dryers. These compressors offer stable airflow, lower noise, and improved efficiency compared to piston units.
They are commonly used in precision machining, packaging lines, laboratories, and small workshops requiring reliable continuous air.
GA / GA⁺ Series
General factories require long-life compressors with proven reliability.
The GA and GA⁺ Series represents Atlas Copco’s core industrial oil-injected screw compressors.
Covering 5.5 naar 500 kW, this series includes models such as GA30 VSD⁺ and GA250. Most units operate at 7.5–13 bar using single-stage compression, with the GA⁺ line offering higher energy efficiency.
They are widely used in automotive, electronics, general manufacturing, and food processing backend applications.
GR Series
High-power users face rising energy costs at larger capacities.
The GR Series is a two-stage oil-injected screw compressor optimized for high-efficiency, high-power applications.
Ranging from 55 naar 500 kW, models such as the GR200-2S deliver 8–10% energy savings compared to single-stage compressors under stable loads.
This series is typically used in steel plants, cement factories, and other heavy industries with continuous air demand.
ZR / ZT Series
Air purity failures can shut down entire production lines.
The ZR and ZT Series provides 100% oil-free compressed air for critical processes.
Covering 55 naar 900 kW, these oil-free screw compressors include models like ZR200 VSD⁺ and ZT90, with air-cooled and water-cooled options available.
They are widely applied in pharmaceutical manufacturing, food and beverage processing, electronic front-end production, and instrument air systems.
SF / SF⁺ Series
Noise and air quality are critical in sensitive environments.
The SF and SF⁺ Series is an oil-free scroll compressor designed for quiet and clean operation.
This range covers 1 naar 22 kW. Models such as SF6 and SF⁺8 operate at noise levels below 65 dB, allowing installation close to work areas.
They are commonly used in laboratories, hospitals, dental clinics, and clean rooms.
ZH / ZH⁺ Series
Large plants require massive air flow at constant pressure.
The ZH and ZH⁺ Series are oil-free centrifugal compressors for very large-scale air systems.
Starting from 200 kW and reaching up to 5 MW, representative models include ZH350 and ZH7000, operating at 2–13 bar.
They are ideal for centralized air stations in chemical plants, textile factories, and other process industries.
LT / LT Piston Series
Some applications need high pressure rather than high flow.
The LT and LT Piston Series serves small-flow, high-pressure compressed air needs.
Covering 0.5 naar 15 kW, these compressors include oil-free and oil-injected versions. Models such as LT2-30 can reach pressures up to 30 bar.
They are used for point filling, laboratory testing, and specialized industrial tasks.
SJAH / Xas / XAHS Mobile Screw Series
Field operations demand mobility and extreme durability.
The XA, Xas, En XAHS Series are mobile screw compressors built for outdoor and harsh environments.
Operating from 7 naar 35 bar, these diesel or electric units include models like XAS186C and XAHS166C, often equipped with tropical kits rated up to 55°C.
They are widely used in mining, municipal works, oil and gas exploration, and emergency repairs.
DrillAir / High-Pressure Mobile Series
Some projects require very high pressure in remote locations.
The DrillAir and High-Pressure Series delivers mobile compressed air at extreme pressures.
Operating at 25–35 bar, models such as the DrillAir V28 deliver up to 28 m³/min bij 35 bar.
They are primarily used for pipeline pressure testing, geothermal drilling, and pile foundation construction.
Conclusie
Atlas Copco’s compressor series are designed for clearly defined industrial needs. Understanding these nine core series helps users select the right technology, control operating costs, and ensure long-term system reliability.
