Atlas Copco X-Air 1100-25 vs. X-Air 750-25: mobile diesel compressors for heavy-duty drilling and foundation applications

In drilling and foundation projects where high pressure and constant air supply are crucial, the market is opting for robust compressor technology. With the X-Air 1100-25 and X-Air 750-25, Atlas Copco offers two mobile diesel compressors that can be used in the most demanding conditions. Machinery Resale - specialist in mobile energy solutions - compares both models in terms of capacity, mobility and area of application, including a recent reference project at the port of Matadi (DR Congo).

Atlas Copco X-Air 1100-25: maximum air capacity for deep drilling and infrastructure projects

The X-Air 1100-25 is designed for heavy-duty industrial applications where air output and pressure determine productivity. This two-stage screw compressor delivers up to 30 m³/min at 18 bar, with a maximum working pressure of 25 bar. Powered by a Caterpillar C9.3 diesel engine (Stage IIIA), this model combines power, endurance and precision control through the Atlas Copco XC4004 controller.

• Flow rate: 28-30 m³/min depending on pressure level

• Pressure range: 16 to 25 bar

• Weight: approx. 6,000 kg

• Engine: Caterpillar C9.3 is a powerful six-cylinder engine that guarantees high torque at low speeds - ideal for applications requiring continuous air delivery under heavy loads.

Thanks to AirXpert technology (including ECO mode and automatic load/unload), the 1100-25 performs with optimized fuel consumption. Optional features such as remote control, wagon wheels or off-road undercarriage make this model deployable on rugged terrain.

Typical applications:

• Deep drilling in hard rock

• Foundations and injection drilling

• Sandblasting and underground mining

• Concrete and infrastructure works with high air requirements

Atlas Copco X-Air 750-25: compact 25-bar compressor for mobile foundation projects

The X-Air 750-25 offers a more agile solution for soil drilling, geothermal and foundation projects. With a Cummins QSB6.7 Stage V engine (231 kW), this compressor delivers a constant airflow of 21.2 m³/min at 16 bar, while maintaining performance up to 25 bar.

• Flow rate: 19-21 m³/min

• Pressure range: 16-25 bar

• Weight: approx. 3,500 kg

• Engine: Cummins QSB6.7 (Stage V)

Its lower weight and dual axle chassis make transportation easy with a standard truck or all-terrain vehicle. AirXpert control ensures fuel savings of up to 10% over the previous model. The Xc2004 controller ensures user-friendly pressure and flow settings tailored to the application.

Typical applications:

• Geothermal drilling to mid-depths.

• Water extraction and CPT drilling

• Foundation work in hard-to-reach locations

• Mobile applications where compactness is essential

Technical comparison X-Air 1100-25 vs. 750-25

Project case: six Atlas Copco X-Air 1100-25 compressors for Eiffage in Congo

For the expansion of the Matadi container terminal in DR Congo, contractor Eiffage Génie Civil Marine chose six new X-Air 1100-25 compressors, supplied by Machinery Resale. This project required high working pressures and air volumes for large-scale drilling, anchoring and concrete injection. Thanks to their reliability, high uptime and robust build quality, the 1100-25 models form the heart of the compressed air supply on the site.

The compressors were shipped from Belgium and are used on site daily, under tropical conditions, with no loss of performance.

Conclusion: which compressor is right for your project?

The Atlas Copco X-Air 1100-25 focuses on large infrastructure projects and heavy drilling, where maximum air capacity is essential. In contrast, the X-Air 750-25 offers a light, efficient and flexible solution for drilling and foundation applications where mobility and energy consumption are critical.

Machinery Resale has both models - and several others from the X-Air range - in stock. Our technical specialists will be happy to advise you on choosing the right compressor for your project, including transport solution, maintenance plan and fast delivery.
