The transmission filter is the core of ensuring the power transmission of automobiles. Its core mission is to continuously and efficiently filter various impurities carried by the transmission fluid (ATF) during the circulation process, including metal debris generated by gear wear, friction plate particles, and invading dust. Through its precise internal filter material, it can effectively intercept these harmful particles, ensuring that the transmission fluid always maintains a high level of cleanliness. Not only can it effectively prevent gear shifting jolts, slippage, and even serious malfunctions caused by oil pollution, but it also significantly extends the service life of the entire gearbox and avoids high maintenance costs. The flow range of the transmission oil suction filter produced by Risun covers 10L/min to 60L/min. The efficiency and dust holding capacity testing standards meet the requirements of ISO16889.
