The polishing system circulates and cleans fuel by pumping it from the tank, processing it through the cleaning unit and back into the tank. The filters in the unit remove sludge along with other organic/in-organic impurities and water in a continuous process until all contaminants are removed.

JY-219F filters are compact and easy to operate. They provide versatile and reliable filtration for a wide range of industrial applications, helping users keep liquids clean and improve performance. Using Jingyuan® high-performance membrane filtration technology to filter and refine oil products, filter out particles, moisture, acid and oil degradation products (varnish) in hydraulic oil, lubricating oil, gear oil, diesel oil, and improve the cleanliness quality level of oil products.

The DM50 Fuel Polishing System is a cost effective way to filter diesel, jet fuels, mixtures of bio diesel, and other petroleum hydrocarbon fluids in storage or transport.

JY-219A portable filter has a compact structure, high precision and easy operation. Designed specifically for filtering and purifying diesel fuel, it uses JINGYUAN® high-performance membrane filtration technology to filter and refine diesel fuel to filter out impurity particles, colloids and moisture, improve the cleanliness

JY-210 with stainless steel tank body is a small diesel purification filter that removes harmful impurities in diesel oil, separates oil and water, protects the engine, reduces failures, reduces wear, protects the fuel injection nozzle system, improves the engine reliability, and the filter element has a long service life. It is suitable for installation on various vehicles and construction machinery.
