Portable Diesel Screw Air Compressor
The portable diesel screw air compressor features a wide range of adjustable core performance parameters.
It offers volumetric flow options of 33 m³/min and 35 m³/min, providing flexible compatibility with different air demand scales.
It can reliably supply intermittent air for small production lines or continuous air for large industrial operations.
Exhaust pressure options of 2.5 MPa and 3.0 MPa meet requirements ranging from general industrial use to high-pressure processes such as mining and high-pressure spraying.
The SPM 1200 operates in ambient temperatures from –20 °C to 40 °C, ensuring reliable performance in extreme cold or heat. The air-cooled design eliminates dependence on complex water circulation systems, reducing downtime risks in remote or water-scarce environments. Maximum exhaust temperature is strictly controlled at ≤130 °C, ensuring operational stability under heavy load and extending equipment service life.
