Kaishan LGCY diesel mobile screw compressors cover both single-stage and two-stage configurations. The single-stage models serve general mobile drilling and construction air supply; the two-stage models address higher-pressure drilling duties. The line uses Yuchai/Cummins diesel engines and is suited to off-grid mining, road construction, oilfield exploration and water well work. Match pressure and air delivery to the rig and hammer before selecting a model. At publication, the LGCY range covers 17 single-stage models and 25 two-stage models. Compare the two tables below and match pressure and air delivery to your rig and hammer.

Frequently asked questions

What discharge pressure range does the LGCY Diesel Mobile Air Compressor Series cover?

The published models cover 0.5–3.5 MPa discharge pressure; exact values are in the model table above.

What air delivery range does the LGCY Diesel Mobile Air Compressor Series cover?

The published models deliver 5–65 m³/min of air; exact values are in the model table above.

How do I choose between LGCG-45/8 and LGCG-65/5?

Compare the two rows in the model table above — focus on required pressure and air delivery against your drilling tool and rig demand. Our team can confirm the match for your site.

What drilling rigs can this series match?

DTH drilling rigs need air pressure and delivery matched to the hammer in use — tell us your rig and hammer and we will confirm the right compressor model.

Can the compressor be configured to my project?

Yes — standard and optional packages are listed under Configuration & customization above. Send your project details through the inquiry form and we will confirm the matching configuration.
