CNG Compressor Model HF-4MH is a natural gas pressuring device and is mainly used to compress and fill the family-use natural gas to cars, i.e. pressuring the family-use micro-pressured natural gas to 200bar(2900PSI)/250bar(3600PSI) with the gas-filling time for 2 hours each time. It is small in dimensions, light in weight, superior in performance, safe and reliable in operation, durable and economic in application.

This compressor is mainly composed of compressor set, explosion-proof motor, control box, cooling fan, oil/gas separator, pipeline, safety components and frame, etc. At first, the gas runs into the 1st stage cylinder through the gas intake pipe. After the 1st stage compression, the gas runs to the 1st stage cooler and after cooling runs to the 2nd stage cylinder. Thus, after passing through the 3rd stage cylinder and 4th stage cylinder, the pressure of natural gas will be raised to 20MPa. Finally, the compressed natural gas is discharged through the high pressure de-oil filter where the excessive residual oil will be filtered out and fed through the high-pressure hose to fill cars. The compressor is integrally explosion-proof and has the discharge pressure protection. If filling to the setting pressure, the compressor will automatically stop filling. In addition, it fits a safety valve to prevent overpressure.

we have many other types of home cng compressor,such as2/3/4/5/10/20/30/40/50Nm3/h.if you have any interests in our products,pls do not hesitate to contact us.
