How to choose and install the circulating filter element ?

The circulating filter element is set on the circulation circuit of the fuel tank, and is often used in systems with strict cleaning requirements. Even if the system stops working, the system can be activated to minimize the pollution of the system, so it is required to use a fine filter element with a higher filtration ratio. If the system is installed with a cooler, the temperature of the system can be lowered and maintenance is also convenient.
