Kaishan KSZJ Series are deep-well two-stage diesel air compressors for water well and lower-pressure geothermal drilling (per the 2026 Kaishan water-well brochure): two-stage compression with flexible-design intake valves (global invention patent), SKY patented screw air-end rated to 40 bar with SKF bearings, heavy-duty Yuchai/Cummins diesel engines, computer control with remote monitoring, triple filtration, and dual-work-condition switching (e.g. 33 m³/min at 25 bar or 26 m³/min at 35 bar). The series covers discharge pressure 1.7-2.3 MPa and air delivery 18-32 m³/min. At publication, the series covers 6 models with discharge pressure 1.7–2.3 MPa. Air delivery 18–32 m³/min.
