LNG and CNG models, more and more widely used in the market, such models of fuel natural gas filters, respectively, there are high pressure filters, medium pressure filters and low pressure filters, which are different from ordinary fuel filters, in the maintenance and use of the process to be different.

Gas filter maintenance points
1. Maintenance of natural gas filter, similar to oil-water separator. Includes regular water discharge, blowdown and filter cartridge replacement. Before the filter starts maintenance, it is necessary to close the on-off valve and slowly release the line pressure. Otherwise, it may cause dangerous accidents, especially the high-pressure filter element.

2. Pay attention to water discharge and sewage discharge every 3000 kilometers under normal circumstances or if necessary. After the system pressure is released, unscrew the blowdown valve for blowdown until the liquid runs out, and then close the blowdown valve.

3. The content of natural gas impurities directly determines the life of the filter element. Replace the filter cartridge every time the oil is changed or every 10,000 km. If the air source is clean, the filter replacement mileage can be extended to 20,000-30,000 kilometers.
