Excavator Oil Filter 1R0739 Filter Replacement Hydraulic Oil Filter Element

 Research on the Compatibility of Fuel Filter Elements for National VI Emission Standards

 ■ The new standard requires decomposition

Filtration accuracy: Increased from 10μm to 5μm absolute filtration

Water separation efficiency: ≥95% (ISO 16332 standard)

Sulfide tolerance: Continuous test of 500ppm sulfur-containing fuel for 200 hours

■ Accelerated aging tests of the Biodiesel Challenge Laboratory show:

The common rubber seal swelled after 72 hours

The improved fluororubber scheme can pass the 300-hour test

It is recommended to add a drainage operation every 250 hours
