High Efficiency Engine Primary Panel Air Filter 5261250 PA31000 AF55015 for Cummins QSB6.7 QSC QSC9 QSL9 for Fleetguard

Common sense of good and bad filters

All filters protect engine components, clean and extend engine life. It is not correct to judge the quality of the filter from the surface of the various filters and the age of the filter. The quality of the equipment should first be considered from the following aspects:
1. The filter paper is good or bad
There is no difference between high-quality filter paper and low-quality filter paper on the surface. Only by testing under the testing equipment of professional factory can there be obvious differences. The quality of the filter paper is related to the efficiency of the filter. There are many impurities, iron and dust in the system, and inferior filter paper filters impurities, iron and dust.
2. The filtration efficiency of the filter
It is mainly determined by the quality of the filter paper used in the filter. Filters with a filtration efficiency of more than 96% are qualified products. At the same time, in the same place, the use of filters from different manufacturers is different. The obvious difference is that there is a significant difference in how the driver feels about the engine and the smoke level of the car exhaust when the engine is started, while driving, when servicing the engine and wearing parts.
3. Filter paper and end cap adhesive material
There are high-quality filter papers and high-quality adhesives. If not properly selected, the filter paper in the filter will not bond firmly to the upper and lower end caps. It is easy to fall off when encountering oil, and it is non-sticky. Causes a short circuit and cannot be filtered.
4. Guarantee of the production process.
On the surface, the filter paper and the filter paper cannot stick together. Transmittance must be visible in light. If there is no light transmission under the light, the adhesion of the filter paper will affect the flow of the entire filter, the service life will be short, resulting in insufficient power, poor physical properties, and difficult to remove dust during the cleaning process. A good filter, non-adhesion between filter papers, strong light transmittance, suitable for the latest standard of the engine, long service life, and easy to clean.
5. Filtration process
Selection of high-quality materials to produce filters, production technology is the backing to ensure product quality. There are many steps in the production of filters. How to ensure that the filter can not only protect and purify during use, but also ensure the flow and ensure the normal operation of the engine, requires process guarantees in all aspects of the production process.
