Compared with chemical fiber filter material, glass fiber filter material has the following advantages: 1. The filtration efficiency is stable, and the chemical fiber filter material may cause a sudden drop in efficiency due to electrostatic attenuation 2, the pressure drop rises slowly, and the service life is at least 1 times longer than the chemical fiber filter material (Note: laboratory test results) 3, the working temperature can reach 110-120 degrees Celsius, and the fire rating reaches UL-1 (polyester non-woven backing) and UL-2 (glass fiber) mesh backing). Chemical fiber filter materials are flammable and flammable materials. 4. Unlike the chemical fiber filter material with static electricity, the dust particles passing through the glass fiber filter material will not carry static electricity, which will not increase the chance of damage to microelectronics products. The chemical fiber filter material will cause the entire clean room space to carry static electricity. 5. The filter fiber adopts a special component formula, which can be quickly dissolved in human lung fluid and excreted from the body. It will not stay in the human body for a long time like chemical fibers6. Although the procurement cost of chemical fiber filter materials is low. However, by saving labor, saving electricity consumed by upstream air volume, and improving the yield of customer products, glass fiber filter materials have lower life-cycle costs and lower enterprise operating costs. Main application: Main filter for commercial, industrial, clean room ventilation and air conditioning systems
