This type of filter paper is made of all-gel material and has high filtration efficiency. It is suitable for complex environmental requirements. Its features are as follows:
1. Filter accuracy adaptation: It meets the air intake requirements of light vehicle engines, effectively filtering dust, sand, and other particle impurities (typically capable of filtering particles ≥ 5μm), while also ensuring the interception of fine dust, reducing wear on engine cylinders, pistons, etc.
2. Good air permeability: With a reasonable fiber pore structure, it reduces intake resistance while maintaining the filtration effect, ensuring that the engine can obtain sufficient and smooth intake volume under different operating conditions, and avoiding power loss.
3. Strong resistance to temperature and humidity: It can adapt to the high-temperature environment inside the engine compartment, and is unlikely to deform or clog up when encountering humid air, maintaining stable filtration performance.
4. Precise size and easy installation: Designed according to the specifications of different air filter boxes for light vehicles, it can be installed closely and tightly to seal, preventing unfiltered air from directly entering the engine.
