The Chicago Pneumatic CPS 750 JD7 Tier IVa rotary screw, portable compressor generates 750 CFM of air at 100 psi. Powered by a 200 hp (149 kW) John Deere six-cylinder diesel engine, the CPS 750 JD7 is Tier IVa compliant and designed for heavy-duty construction environments.

The CPS 750 JD7 Tier IVa utilizes a new and improved air end with an advanced rotor profile. This air end has been engineered to reduce the horsepower required to produce the 750 CFM, resulting in better fuel efficiency. The air pressure is adjustable from 58 psi up to 100 psi.

The John Deere engine uses exhaust gas recirculation technology to reduce NOx emissions. The exhaust gases are cooled and reintroduced to the engine cylinders, resulting in lower peak combustion temperature, reducing NOx formation. A particulate filter is then used to remove the increased amount of particulate matter in order to meet the new Tier IVa emission standards.

The electronically controlled, water-cooled engine, variable speed fan and new Chicago Pneumatic air end reduces fuel consumption to 8.2 gal. (31 L) per hour at 100 percent load — a significant reduction in fuel consumption. In addition, with the 78-gal. (295 L) fuel capacity the operator gets more than a full 8-hour day at full load.

The new CPS 750 JD7 Tier IVa fits cleanly into a single-axle, fast-track enclosure. This new sound-dampening enclosure is more compact than competitively sized compressor packages, according to the manufacturer. The CPS 750 JD7 Tier IVa features an A-frame drawbar, surge hydraulic brakes and torsion bar suspension, which provides durability, stability and optimal road performance when in tow. The CPS also is available in a support-mounted configuration.

The steel, gull-wing enclosures also provide easy access to the engine and all service points, so routine maintenance can be completed quickly and conveniently.
