Respiratory Filter 11707077 For A20CA35EL220H Heavy Duty Truck Engine Parts

Respiratory Filter 11707077 Is Suitable For A20CA35EL220H Heavy Duty Truck Engine Parts Air Filter

Product Description:

Construction machinery often operates in harsh environments with extremely high dust concentrations, such as mines and construction sites. When the engine is working, a large amount of air needs to be inhaled. If it is not filtered, hard particles such as dust and sand in the air will enter the cylinder, accelerating the wear of the piston group, cylinder wall, and valve mechanism. In severe cases, larger particles can cause fatal malfunctions such as "pulling the cylinder" and "bursting the cylinder". The air filter can effectively intercept these particles, ensuring clean air entering the combustion chamber.

Clean air helps to create an ideal fuel air mixture ratio, allowing for more complete combustion of fuel. This not only improves the stability of the engine's power output, but also reduces fuel consumption and emissions of harmful substances in the exhaust, meeting environmental requirements.

Features:

1. Construction machinery often operates in high dust environments such as mines and construction sites. Air filters need to have extremely high filtration efficiency (usually up to 99.5% or more), which can effectively intercept small dust, stone powder and other impurities in the air, prevent them from entering the engine cylinder, and avoid serious wear and tear of plugs, cylinders and even "cylinder pulling" faults. ‌

2. To adapt to long-term, high-intensity continuous operations, air filters commonly use materials such as metal wire fabrics, foam materials, or specially treated filter paper. These materials have higher mechanical strength and weather resistance, and can withstand physical impacts and long-term use under harsh working conditions. ‌

3. In extremely dusty environments, wet air filters are still widely used. This type of filter element captures dust by adhering to the oil medium, with high filtration efficiency. The metal filter element is more resistant to wear and flushing than dry filter paper, making it particularly suitable for large diesel engines. ‌

4. Efficient air filters should ensure filtering effectiveness while minimizing intake resistance to ensure sufficient and smooth airflow for the engine, maintaining power output and fuel efficiency. Modern construction machinery filter cartridges achieve high dust holding capacity and long service life by optimizing structure and materials, reducing maintenance frequency in remote construction sites and lowering operating costs. ‌

5. The sealing performance between the filter element and the housing is crucial. Any unfiltered air entering the engine through a bypass will cause accelerated wear and tear. Therefore, the rubber seals and other components of the air filter element in construction machinery need to ensure absolute sealing under various vibrations and pressures. ‌
