Low-Pressure Portable Diesel Air Compressor (7-8 Bar)

A Low-Pressure Portable Diesel Air Compressor typically operates between 7 to 8 Bar (100-115 psi). It runs entirely on an internal diesel engine, requiring no electrical grid. They are primarily used in outdoor engineering to drive pneumatic tools (jackhammers, rock drills), power sandblasting equipment, blow out pipelines, and assist in fiber optic cable laying.

Standard compressors often just toggle mechanically between full load and unload. The stepless capacity control system on our Low-Pressure Portable Diesel Air Compressor instantly senses pressure changes in your air hoses. If your operators stop using their pneumatic tools, the system automatically and smoothly reduces the engine speed to idle, drastically cutting unnecessary fuel consumption.

The entire Powerlink mobile compressor series utilizes high-precision, industrial oil-injected twin-screw airends. Unlike traditional piston compressors, twin-screw airends have no fragile valves, produce minimal vibration, and deliver a 100% continuous, pulse-free stream of massive airflow with an exceptionally long service life.

Selection depends entirely on the total air consumption of your pneumatic tools. If you are running 1-2 small breakers, our compact DS120-7 (123cfm) is sufficient. For large-scale sandblasting or driving heavy drill rigs, you will need a massive unit like the DR950-8 (844cfm) or DR1250-8 (1225cfm). Tally up the CFM requirements of all your tools, and our engineers can match you with the perfect model.

Absolutely. They are engineered for global extremes. They feature a high-performance thermal management system (rated for up to 50°C ambient temperatures) and dedicated cold-start aids, ensuring reliable ignition and stable air supply even in freezing -25°C environments.

We designed the canopy with mechanics in mind. Smaller models use a wide-opening clamshell design, while larger models feature dual gull-wing doors. Once opened, the air filters, oil filters, air/oil separators, and fuel fill points are completely exposed, allowing one person to perform routine maintenance effortlessly.

All Diesel Air Compressor utilize high-efficiency oil-injected twin-screw rotary air ends, ensuring continuous pulse-free air delivery.

Our units come standard with dual-stage air filtration to block site dust from entering the airend. If your application (such as specialized painting or blasting) requires extremely strict dry and oil-free air, we can equip your Low-Pressure Portable Diesel Air Compressor with optional aftercoolers and precision water separators.

We take noise compliance seriously. The interior of the canopy is lined with thick, industrial-grade fire-retardant acoustic foam, paired with a heavy-duty exhaust muffler. This sound-attenuated enclosure keeps operational noise well within industry standards, making them suitable for road repairs near residential or urban areas.

The PLC system provides intelligent automation, including real-time telemetry, digital pressure monitoring, maintenance alerts, and automated safety shutdowns.

We know that refueling mid-shift is a costly logistical headache. Therefore, every Low-Pressure Portable Diesel Air Compressor in our lineup is equipped with an oversized internal fuel tank. Under normal load conditions, a single full tank provides enough diesel for 8 to 10 hours of continuous operation, easily completing a full work shift without stopping.
