Whether the quality of the air filter is good mainly depends on the following three aspects:
(1) waterproof performance;
(2) Filtration accuracy;
(3) Air permeability.
The specific tests are as follows:
1.Water testing. Place the air filter on the ground or on the table and sprinkle some water on the filter paper;
(1) If the filter paper seeps out within 5 minutes, it is an air filter made of cotton pulp paper (inferior filter paper);
(2) If the filter paper seeps for 2-5 hours, it is made of low-grade wood pulp paper. It can be used, but it will reduce the gas production efficiency of the air compressor (more power consumption, more gas production) .It is the primary effect filter;
(3) If the filter paper seeps for 12-15 hours , it is a medium efficiency filter;
(4) If it does not seep into water for 24 hours, it is a high-efficiency filter.
2.Looking at the filter paper through the light ,so that you can see whether the filter paper is uniform, the transparency and the surface finish of the filter paper is good. The response is the filtration accuracy and the amount of ventilation.
(3) Look at the depth and the number of folds of the filter paper. If the filter paper is deep, the number of folds of the filter paper is large, indicating that the filter area of the air filter is large.
Users with particularly harsh environments are advised to tidy up the air filter once a day, 500-800 hours to replace the air filter; customers in the medium environment have an air filter for 3-7 days, 1000-1500 hours to replace the air filter; customers with good environment 1500-2000 Replace the air filter once every hour.
