1. The compressor of the sub-station is used to input natural gas through the pipeline, pressurize it in the station, or store it directly into the fixed gas storage cylinder group (well) to fill the CNG vehicle with compressed natural gas.
2. The wearing parts such as air valve and piston ring are made of high-quality products, with a service life of more than 8,000 hours.
3. Soft start, allowing the compressor to start and stop frequently. Wide range of air intake, wide adaptability

The overall skid-mounted structure has low noise and is easy to install in urban areas to save investment.

• The advanced micro- control system is composed of program control, display panel control, report and pressure control system, IP interface, and telephone modem.
• Crosshead and piston rod are connected by the unique LMF crosshead coupling without thread on the piston rod.
• Forced oil feed from the crosshead, small-end, and large-end connecting rod bearings avoids weakening of the crankshaft with oil passages.
• The unique and big LMF lubrication oil tank can reduce the frequency of oil circulation.
• Identical, interchangeable main and crankpin bearing sleeves reduce and simplify spare parts requirements. Axial crankshaft loads are carried by a separate bearing and the connecting rods are axially guided in the crossheads. Only cylindrical, hydro-dynamically optimized main and crankpin bearing surfaces without shoulders and circumferential grooves are used.
