389-1079 Hydraulic Oil Filter Element Engineering Machinery Oil Fuel Filter Element 3891079 Excavator Filter Element

Description:

Oil filters have higher requirements for filter paper than air filters, mainly because the temperature of the oil varies from 0 to 300 degrees. Under severe temperature fluctuations, the concentration of the oil also changes accordingly, which will affect the filtration flow rate of the oil. The filter paper of high-quality engine oil filters should be able to filter impurities under severe temperature changes while ensuring sufficient flow rate.

Advantages:

There are two types of oil filters: full flow and split flow. The full flow filter is connected in series between the oil pump and the main oil passage, so it can filter out all lubriing oil entering the main oil passage. The split flow cleaner is connected in parallel with the main oil channel, and only a portion of the lubriing oil sent out by the filter oil pump is filtered.
