Screen filters are a broad general term for filters, and in contrast, there are wire gap filters, glass fiber filters, etc. It is an indispensable device on the pipeline for transporting media, usually installed at the inlet end of pressure reducing valves, safety valves, constant water level valves or other equipment, used to remove impurities in the medium to protect the normal use of valves and equipment.

When the fluid enters the filter cartridge equipped with a filter screen of a certain specification, its impurities are blocked, and the clean filtrate is discharged from the outlet of the filter. When cleaning is needed, just remove the detachable filter cartridge, process it and reinstall it. Therefore, it is extremely convenient to use and maintain.

The screen filter is a precision device that directly intercepts impurities in water, oil and other liquids with a filter screen, removes suspended solids and particles in water and oil, reduces turbidity, purifies water and oil quality, and reduces the generation of system dirt, bacteria, algae, rust and other substances, so as to purify water, oil and other liquids and protect the normal operation of other system equipment.

Water enters the screen filter from the inlet. First, it passes through the coarse filter core assembly to filter out larger particles of impurities. Then, it reaches the fine filter screen. After the fine particles of impurities are filtered out by the fine filter screen, the clear water is discharged from the outlet. During the filtration process of the self-cleaning filter, impurities gradually accumulate in the inner layer of the fine filter screen, thus forming a pressure difference on both the inner and outer sides of the screen filter.
