Common filter materials of self-cleaning filter

The filter materials of self-cleaning filter include metal mesh, metal felt, glass fiber, plant fiber, soft magnetic material and so on. The metal mesh is woven by metal filaments and divided into square mesh and twill mesh. It has low flow resistance and can be used in a very high temperature range. It is mainly used for coarse filtration of the system. It belongs to surface filtration and can be cleaned and used repeatedly.

Metal felt is made of metal fiber. It has the performance of glass fiber and belongs to deep filtration. It has labyrinth three-dimensional structure, high porosity and low flow resistance. It has strong pollution holding capacity and long service life, and can be used in a large temperature range. The accuracy range is 5-20 μ m。 Because of its high price, it can be used only when filtering special media or requiring high temperature. It can be cleaned and reused.

Glass fiber is one of the most common filter materials with the best performance. It is widely used in hydraulic system. It belongs to in-depth filtration, and the accuracy range is 1-30 μ m. It is less affected by the change of working environment, small flow resistance and strong pollution holding capacity. It still has a high ability to filter fine particles beyond the specified differential pressure range. Good chemical tolerance, but not suitable for water glycol mixture.

Organic chemical fiber is also a very good filter material, and its accuracy range is 3-30 μ m. It belongs to in-depth filtration, which can withstand high differential pressure, small flow resistance and large pollutant holding capacity. Strong chemical resistance, especially suitable for emulsion and synthetic hydraulic fluid. Tear resistant, but the accuracy changes slightly with temperature.
