Oil bath type air filter
In order to solve the problem of early engine wear under harsh working conditions, SinotruK has developed oil bath type air filter and compound type air filter. The oil bath type air filter or the combination of oil bath and paper felt filter can effectively improve the air filtration effect, improve the service life of the engine and reduce fuel consumption. At present, this combination filtration method is also used in the harsh use environment abroad. Compared with similar international products, the oil bath air filter has the characteristics of small size and obvious energy-saving effect, and the engine use efficiency can be increased by 20% compared with the traditional air filter method.

Oil bath type air filter instructions
1. The new truck is not filled with oil before leaving the factory;
2. Oil needs to be added before operation, and the oil viscosity must be similar to the engine oil at the same time;
3. The oil height shall not exceed the specified oil level height, and the oil volume is 5L;
4. When the bottom shell is shaken and the oil is not easy to flow, it is necessary to clean the filter assembly and replace the oil. Under particularly harsh conditions of use, the oil must be checked and cleaned every day. Under normal circumstances, it can be used continuously for 80-150h. The oil filter element can be used for a long time without replacement, and the air filter paper filter element can be replaced at any time according to the actual situation;
5. Check whether the retractor connecting the shell and the bottom shell is loose every day;
6. When cleaning the filter assembly of the air filter, remove the butterfly nut at the bottom of the upper and lower filter shell first.

Desert two-stage air filter
The utility model relates to a two-stage desert air filter, which comprises a coarse filter and a fine filter. The coarse filter and the fine filter form a whole structure, and the outlet end of the coarse filter is connected with the inlet end of the fine filter. Small size, compact structure, beautiful appearance, easy to install, low intake resistance, high filtration efficiency. The filtration efficiency can reach 99.8%.

Desert two-stage filter maintenance method
1. Every 5000 kilometers, please stop and maintain the filter element;
2. When the filter is maintained, remove the outer filter element, rotate it, and blow the dust from inside to outside with compressed air of no more than 588 KPa;
3. Prohibit refueling and water cleaning filter element;
4. After maintenance for 5 times or use of 30,000 kilometers, please replace the outer filter element and safety filter element. Areas with large dust should appropriately shorten the maintenance and replacement cycle;
5. The dust exhaust valve device should be vertically downward, and the dust bag should be squeezed by hand from time to time to discharge the accumulated dust;
6. When maintaining the coarse filter, please remove the outer filter element and the safety filter element, and then blow the dust and dirt in the pipe with compressed air repeatedly up and down;
7. The quality of the filter element is crucial to the service life of the engine and power fuel consumption, please use the original filter element;

In addition, pay attention to the maintenance of the above air filter to prevent sand and dust from being blown directly into the engine intake pipe, causing serious consequences.
