Air Filter Element(Primary Air Filter)AF258123 BLSZ919000918L
While ensuring sufficient intake air flow, control the intake resistance to guarantee the engine's power output and stabilize fuel consumption;
Prevent large foreign objects from entering the intake duct and prevent them from damaging the turbocharger blades;
Combined with the safety inner filter, it serves as a second line of defense when the main filter is damaged..
Product features
1. The multi-layer composite filter paper with large dust absorption capacity is suitable for harsh working conditions such as mining areas, construction sites, and gravel roads.
2. The optimized folding design results in low intake resistance and is less likely to be clogged quickly.
3. The polyurethane PU sealing gaskets at both ends have good elasticity and provide a tight seal, preventing dirty air from leaking (leakage is the biggest potential hazard for engine wear).
4. The inner and outer galvanized metal mesh provides reinforcement and support, ensuring that the filter paper does not collapse or get damaged under vehicle jolts and negative pressure.
5. Standard OEM size, can be directly replaced with the original vehicle air filter housing without any modification.
6. The filter paper is treated with moisture-proof curing process, making it less prone to softening and losing fibers in humid environments.
Solved malfunction issues:
✅ Filter blockage, insufficient intake air, decreased engine power, increased fuel consumption;
✅ Dust entering the cylinder causing early wear and oil leakage of cylinder liners and piston rings;
✅ Impurities damaging the turbine turbocharger blades;
✅ Air filter seal not tight, dirty air bypassing and entering the engine, leading to premature engine maintenance;
✅ Dust environment filter quickly clogging, shortening maintenance cycle.
Material
1. Filter medium: Native wood pulp + fiberglass composite filter paper, with high precision filtration;
2. Supporting framework: Inner and outer galvanized metal mesh, resistant to deformation;
3. Sealing components: PU polyurethane elastic rubber, resistant to high and low temperatures, with long-lasting sealing;
4. End cover: Metal pressed end cover.
Q: Can it be cleaned with cleaning tools? Can it be reused repeatedly?
A:1. Temporary emergency cleaning can be done using low-pressure dry compressed air, but it is strictly prohibited to use it repeatedly as a regular practice.
Conditions: Air pressure control 0.2–0.3 MPa, blow from the inner side of the filter element outward, do not blow directly at the filter paper with a high-pressure air gun from close range;
Restrictions: The emergency blowing can be done at most once, it cannot be repeatedly cleaned;
Prohibitions: Water washing, liquid cleaning.
2. In any of the following situations, it must be replaced directly, and cannot be cleaned and reused:
Filter paper is damaged, has micropores; Filter paper is stained with oil, water, or gets damp and caked; Gasket is cracked; Guard net is deformed.
Principle: The paper air filter has a paper fiber structure. Each blowing will tear the fine fibers, the pore size will increase, the filtering capacity will permanently decrease, and dust will directly enter the engine.
