Basket filter is a small equipment to remove a small amount of solid particles in the liquid, which can protect the normal operation of the equipment. When the fluid enters the filter cartridge with a certain size of 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 removable filter cartridge is taken out, it can be re loaded after treatment. Therefore, it is very convenient to use and maintain.
