Risun-produced oil and diesel filters are widely used in automotive engines, marine engines, agricultural equipment, and construction machinery.

The centrifugal oil filter uses the centrifugal force generated by the high-speed rotation of a rotor to separate mechanical impurities from the oil and deposit them on the inner wall of the rotor, thereby purifying the oil. Its advantages include improving lubricant cleanliness and engine reliability, and extending the service life of the main filter. The minimum start-up flow for the Risun centrifugal oil filter is 2L, allowing it to be used in bypass pipeline systems. The product's performance has received positive market feedback.
