Durable, rugged portable air compressors for on-site use
The Chicago Pneumatic CPS 250-150, CPS 400-150, and CPS 400-200 mobile air compressors are engineered to deliver reliable and portable compressed air for demanding construction, utility, and rental operations. Powered by efficient diesel engines, these mobile compressors provide 238-375 cfm airflow at pressures ranging from 100-200 psi, ensuring consistent performance across challenging job sites. Their high output and robust design make them ideal for a wide range of applications, including sandblasting, fiber optic cable blowing, operating pneumatic tools, and pipeline maintenance, while supporting productivity in remote or power-limited environments.
Advanced XC2003 control system
All units of diesel air compressors in this range feature an advanced XC2003 controller for diagnostics and smooth operation. This allows operators to monitor pressure settings simply through the control panel, engine codes, service timers, temperatures, pressures, fuel levels, fuel consumption, and to load or unload the compressor.
Durable Redrock™ canopy with easy service access
These units are also equipped with our rugged Redrock™ canopy and spillage-free frame, built for durability and environmental protection. Our CPS 250-150 features dual pressure, that allows for two pressure presets which are determined by the mechanical regulating valve. Additionally, the clam shell canopy and quick-maintenance design provide easy service access, helping technicians perform inspections and maintenance quickly and efficiently.
DPF-free design for maximum uptime
The CPS 400-150 and CPS 400-200 air compressors are built for reliable performance and maximum uptime on demanding job sites. Its DPF-free design avoids regeneration cycles and reduces unexpected shutdowns, while automatic low-fuel shutdown protects the engine. Fast, simple maintenance, including oil separator service and full oil changes in under 10 minutes minimizes downtime and keeps crews productive.
Multi-pressure technology for ultimate job flexibility
If you’re looking for maximum job flexibility, the CPS 400-200 portable air compressor is engineered to adapt to a wide range of on site requirements with advanced multi pressure technology. This allows electronic adjustment of pressure settings between 100-200 psi in precise 2 psi increments, making it ideal for crews using different pneumatic tools, handling varying materials, or working under changing job conditions throughout the day.
Industries and applications
Powering pneumatic handheld tools: All portable air compressors in this range deliver 100 psi, enough to power any pneumatic handheld tool. Models like the CPS 175-100 and CPS 185-100 can even run two 90 lbs breakers at once, making them ideal for breaking concrete, asphalt, or tile.
Pipeline & utility operations: Compressors pressurize pipelines for leak detection and pressure testing, power pneumatic actuators to operate valves, and can push pigs through pipes to clean them from end to end.
General construction applications: These portable air compressors are widely used to power construction breakers, drills, rivet busters, and sandblasting equipment. They also help clean debris and operate air-driven pumps, making them essential for both heavy-duty and finishing tasks.
Road & bridge maintenance: In road or bridge deck maintenance, air compressors power pneumatic breakers, drills, and sandblasting tools, and blow debris from cracks before sealing. They also help dry surfaces quickly for durable repairs.
Agriculture & farm equipment: These portable air compressors clean equipment and blow out combines to prevent debris buildup, overheating, and fire risks. They also power pneumatic seeders, sprayers, and other farm equipment for efficient operation.
Painting & coating operations: For painting and coating, compressed air cleans surfaces and operates spray guns. These portable air compressors allow on-site painting of equipment, pipelines, and steel structures with professional results.
Shotcrete & gunite applications: For shotcrete/gunite work air compressors supply air for concrete spraying in tunnels, pools, and structural reinforcement
Mining & quarry operations: Our air compressors power drills and other pneumatic equipment in remote mining and quarry environments, delivering reliable compressed air where access to electricity is limited.
Temporary industrial plant air: When a stationary industrial air compressor goes down in a factory or is due for service, the CPS 400 is suitable for temporary backup plant air.
