Doosan Leads Industry With Two New Tier 4 Final Air Compressors

Doosan Portable Power is introducing two new models of Tier 4 Final air compressors — and now offering the industry’s largest lineup of Tier 4 Final units.

The powerful HP750WCU and XP825WCU are the first fully Tier 4 Final-compliant large air compressors in the industry. Powered by a Cummins QSB6.7 Tier 4 Final engine, the HP750 and XP825 offer the same great performance and reliability that is expected from Doosan Portable Power air compressors.

A simple and reliable diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR) after treatment system has replaced the Diesel Particulate Filter (DPF) system used in previous Tier 4 interim models, making these machines virtually maintenance-free.

“By combining the latest engine technology with easy-to-use, easy-to-maintain features and a compact footprint, the HP750 and XP825 are engineered to deliver the power and versatility needed to meet the demands of challenging jobsite conditions,” says Rus Warner, manager, global air products, Doosan Portable Power.

Producing 750 cubic feet per minute (cfm) at a rated operating pressure of 150 pounds per square inch (psi), and 825 cfm and 125 psi, respectively, the HP750 and XP825 are ideal for general construction, abrasive blasting, or pipeline pressure testing. Both models are an obvious choice for the rental market, providing a cost-effective, large air compressor with quality engineering that allows them to remain in the rental fleet long term.

Not only do the HP750 and XP825 sport high-performing engines, but both models also benefit from a cool-box design that improves performance when operating in high ambient conditions, eliminating long cool-down periods and extending the service life of the machine.

A large fuel tank offers nine hours of runtime at full load. Placement of the fuel tank over the axles provides better balance when lifting or towing, regardless of fuel levels. Towing is further improved by heavy-duty tandem axle trailers and 7-gauge steel fenders for reliable, stress-tested transport.

Productivity is maximized by an intuitive and innovative full-color digital display that puts the operator in complete control, eliminating the need for continual machine monitoring. Back-lit LED gauges provide instant access to critical information needed to optimize uptime and ensure efficient machine operation.

Side-by-side oil coolers allow for easy cleaning, while wide service doors provide safe access to routine service points.
