Filter/Filter Element

Net type oil filter

The filter element of the mesh oil filter takes the copper mesh or stainless steel mesh as the filtering material. It is surrounded by a very porous plastic or metal cylindrical framework and covered with one or two layers of copper wire mesh. The filtering accuracy depends on the number of layers of the copper mesh and the size of the mesh.This kind of oil filter is simple in structure, large in flow capacity, convenient in cleaning, but low in filtration accuracy.

Line gap oil filter

Wire-gap filter, with steel or aluminum wire tightly wound in the outside of the cylindrical framework to form the filter core, rely on the copper wire between the small gap to filter out the impurities in the liquid.Its structure is simple, the flow capacity is large, the filtration accuracy is higher than the net type oil filter, but not easy to clean, mostly for the return oil filter.

Paper oil filter

Paper oil filter, whose filter core is a paper core made of plain or corrugated phenolic resin or wood pulp microporous filter paper, surrounds the paper core on the frame made of tin iron with holes to increase the strength.In order to increase the filtration area, the paper core is generally folded.Its filtration precision is high, generally used for oil fine filtration, but after blocking can not clean, must often replace the filter element.

Sintered oil filter

Sintered oil filters, whose elements are sintered with metal powder, use tiny holes between the particles to block the passage of impurities in the oil.Its filter element can withstand high pressure, good corrosion resistance, high filtration accuracy, suitable for high pressure, high temperature hydraulic system requiring fine filtration.
