Built for Continuous Use on Demanding Sites
Atlas Copco mobile air compressors are designed for sustained operation in harsh environments. From compact units for small tool applications through to high output machines for heavy duty work, every model is engineered for reliability, fuel efficiency, and long service life.
Durable components, proven compressor elements, and protective canopies help ensure consistent performance in dusty, wet, or exposed locations. Long service intervals and straightforward maintenance keep downtime to a minimum and help control operating costs over the life of the machine.
A Compressor Range to Suit Every Application
We offer a wide selection of mobile air compressors, allowing you to choose the right output and configuration for your work:
Small portable compressors
- Airflow from 50 to 174 cfm.
- Suitable for handheld tools, fencing, kerb laying, and light site work.
Medium portable compressors
Airflow from 175 to 550 cfm.
Ideal for utilities, civil engineering, groundworks, and drilling support.
Large portable compressors
- Airflow above 550 cfm.
- Designed for quarrying, abrasive blasting, and high air demand applications.
Mobile electric compressors
- Electric powered options deliver low noise operation and zero on-site emissions. Well suited to urban locations, indoor work, tunnels, and low emission zones.
- Many models are available with variable pressure control, allowing one compressor to support multiple applications without changing equipment.
Designed with Transport and Safety in Mind
Mobile air compressors are built for easy towing and positioning on site. Compact layouts, balanced chassis designs, and secure lifting points simplify handling. Integrated spill containment and corrosion protection help protect both your site and your investment.

What is a mobile air compressor and what is it used for?
A mobile air compressor is a towable or skid-mounted machine that produces compressed air for use on construction and industrial sites. You use it when you need reliable air power away from a fixed electrical supply.
Compressed air drives pneumatic tools and equipment. This includes breakers, rock drills, impact wrenches, sandblasting pots, spray painting equipment and cable blowing systems. On larger infrastructure and quarry sites, mobile compressors support drilling and blasting operations. On smaller sites, they commonly power one or two handheld tools for groundworks, utilities and road repairs.
Because they are designed for transport, you can move them easily between sites and position them close to where you are working. This reduces hose runs and pressure loss, which improves efficiency and control.
What size mobile air compressor do I need?
You size a mobile air compressor based on the air flow and pressure your tools require. Air flow is measured in m³/min or cfm. Pressure is measured in bar or psi. Both figures must match your application.
Start by identifying every tool you plan to run at the same time. Check each tool’s air requirement and add them together. You should then allow a small margin so the compressor is not working at full capacity continuously.
Smaller compressors in the 2 to 5 m³/min range at around 7 bar are typically suitable for handheld tools and light construction work. Medium units in the 5 to 10 m³/min range cover most general construction, utilities and small blasting tasks. Larger compressors, delivering 25 m³/min and above, are designed for drilling, quarrying and high-demand blasting applications.
If your work changes regularly, consider a model with adjustable pressure control. This allows you to set the pressure to suit each job, so one machine can cover multiple applications without oversupplying air.
If you are unsure, provide your tool list and application details. We can size the machine correctly for your site.
What are the different types of mobile air compressors?
Mobile air compressors generally fall into four categories: small diesel, medium diesel, large diesel and electric.
Small diesel compressors are compact and often under 750 kg. They are easy to tow and are commonly used for handheld tools and small crews. Medium diesel compressors offer higher flow rates and suit general construction and utility projects. Large diesel compressors deliver high air volumes for drilling, blasting and industrial applications.
Electric mobile compressors are powered from the grid rather than a diesel engine. They produce no on-site emissions and operate at lower noise levels. This makes them suitable for indoor work, tunnels and low emission zones. Many electric models use variable speed drive technology, which adjusts output to match demand and reduces energy consumption.
Your choice depends on site conditions, emission requirements, available power supply and the tools you need to run.
Are Atlas Copco mobile air compressors any good?
Atlas Copco mobile air compressors have a strong reputation across construction, rail, utilities and quarrying. They are designed for daily site use and focus on reliability, ease of service and fuel efficiency.
Most current models meet Stage V emission standards, which reduces exhaust emissions while maintaining output. Many units include spillage-free frames that contain all operating fluids, which helps protect the environment and meet site regulations. Anti-corrosion coatings and polyethylene canopies help protect the machine and support long-term resale value.
On selected models, features such as ECO mode reduce fuel use during idle periods. Adjustable pressure control systems allow you to match output to the job, rather than running at a fixed setting.
For contractors who rely on their equipment every day, they are a dependable option with good long-term value.
How long does an Atlas Copco compressor last?
The lifespan of a mobile air compressor depends on how you use and maintain it. With correct servicing and proper operation, you can expect many thousands of working hours from a well-maintained machine.
Regular servicing is critical. This includes oil changes, filter replacements and inspections carried out at the recommended intervals. Clean fuel, correct oil grades and proper storage all contribute to longer service life. Operating the compressor within its designed pressure and flow range also reduces wear.
Many models are supplied with standard warranties based on time or operating hours, with extended warranty options available. In practice, compressors that are serviced correctly and used for the right application often remain in service well beyond their initial warranty period.
If you want to maximise lifespan, match the compressor to your application, follow the service schedule and use approved parts.
