1.The role of "three filters"

The function of the oil filter element is to effectively filter impurities in the oil, reduce the oil flow resistance, ensure lubrication, and minimize the wear of various components during operation;

The function of the fuel filter element is to effectively filter impurities such as dust, iron filings, metal oxides, sludge and so on in the fuel oil, prevent the fuel system from clogging, improve the combustion efficiency, and ensure the stable operation of the engine;

The air filter element is located in the intake system of the engine, and its main function is to effectively filter the air entering the cylinder to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat, prevent black smoke, and ensure the normal operation and power output of the engine. Guaranteed.

2."Three-filter" replacement cycle

Under normal circumstances, the replacement cycle of the engine oil filter element is the first 50 hours of operation, and then every 300 hours of operation; the replacement cycle of the fuel filter element is 100 hours of the first operation, and every 300 hours of operation thereafter. The difference in the quality grades of oil and fuel can appropriately extend or shorten the replacement cycle; the replacement cycle of the air filter element used by different models is different, and the replacement cycle of the air filter element should be adjusted as appropriate according to the air quality of the operating environment. Replace the inner and outer filters together. It is worth mentioning that it is not recommended to use compressed air for cleaning the air filter, because the high-pressure airflow will damage the filter paper and affect the filter efficiency.

3. Is the higher the filtration precision of the filter element the better?

The filter element with high filtration precision has a low ash capacity, which is more prone to the risk of jamming, and the service life of the filter element is relatively short. Therefore, the higher the filtration precision of the filter element, the better. A qualified filter element product should strike a balance between filtration precision, filtration efficiency and ash capacity rate according to the operating requirements of the adapted model.

4.Is it necessary to use high-quality filter elements for old machines?

The clearance of parts and components of the old engine becomes larger, the wear is increased, and the requirements for lubrication and fuel cleanliness are higher, which requires the use of high-quality filter elements to ensure lubrication and maintain engine efficiency, reduce engine failures, and delay engine scrap time.
