Fluorine-lined Y-type filter is an anti-corrosion equipment to remove a small amount of solid particles in the liquid, which can protect the normal operation of compressors, pumps, meters and other equipment. When the fluid enters the filter bucket with a certain size of the filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When it needs to be cleaned, as long as the detachable filter bucket is taken out and reloaded after processing, therefore, the use and maintenance is extremely convenient. At present, it has been widely used in petroleum, chemical, pharmaceutical, refrigeration, light industry, environmental protection and other industries. If installed in tandem at the pump inlet or other parts of the system line, it can extend the service life of the pump and other equipment. It can also ensure the safety of the whole system, so Y-type filter is an indispensable equipment in industrial production, so that mechanical equipment (including compressors, pumps, etc.) instruments work and operate normally, to achieve a stable process, to ensure the safe production process.
