Atlas Copco’s XAS 750 JD7 Tier 4a Compressor Meets New Emission Standards


October 27, 2011

Antwerp – Atlas Copco’s XAS 750 JD7 Tier 4a rotary screw, portable compressor generates 750 cfm of free air delivery and 100 psi at normal working pressure. Powered by a 200 hp John Deere six-cylinder diesel engine, the XAS 750 JD7 is Tier 4a compliant and designed for heavy-duty construction environments.

With a fuel tank capacity of 78 gallons, the electronically controlled, water-cooled engine has fuel consumption of 8.2 gallons per hour at 100 percent load. This offers a significant improvement over the previous model.  In order to meet the new Tier 4a emission standards, the engine uses Exhaust Gas Recirculation technology to reduce NOx (nitrogen oxide) 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.

Offering 750 cfm of free air delivery at normal working pressure, the XAS 750 JD7 has an air receiver capacity of 16.7 gallons. The unit’s air end is designed to require less horsepower, resulting in the better fuel efficiency.

The new John Deere Tier 4a engine is installed in a new canopy and frame, similar to the previous XAS 750, so the machine’s footprint also remains the similar.  Atlas Copco expects this canopy & frame combination to support the Tier 4 final variant as well.  The XAS 750 features a single-axle design and an A-frame drawbar and torsion bar suspension, which provides durability, stability and road performance when in tow. The XAS 750 is also available in a skid-mounted configuration.

The steel, gull-wing panel enclosures provide easy access to the engine and all replacement parts, so routine maintenance takes less time.

With a reputation for performance, reliability and efficiency, the XAS 750 JD7 is ideally suited for range of construction applications – from installing fiber optic cables to powering a combination of pneumatic tools such as rock drills or hammers.
