Various debris such as metal wear particle, carbon, oxidant, moisture, powder are generated and flowed in during the machinery operation. The debris is passed through the upper element and filter layer of 110mm and pollutants in 0.1μ or bigger and moisture is removed through the deep bed filter and absorption processes.
 

The air barrier is created by the oil that flows into the filter papers from the element of the roll. This air barrier prevents the passing of oil through the filter paper. 
 

Passing through the filter paper, the contaminated oil is flow down to the lower part. During the process, the pollutant and moisture are completely removed through the repeating filtration process.
