The main filter material of high efficiency particulate air HEPA filter replacement is special glass fiber filter paper, the filter grade of which can reach H13 or H14. The separator of filter material can be made from aluminum corrugated sheet or corrugated cardboard. Besides, high temperature resistant silicon is used as sealant. With metal plates as frames, high efficiency particulate air HEPA filter replacement has good heat resisting, moisture-proof, shockproof performance and fire resistance.
All parts are made with heat-resistant material, this filter can therefore work under the operation environment up to 250℃. Therefore, it can be widely used as main filters of commercial, industrial and cleanroom's ventilation and air conditioning system, especially suitable for air filtration in high temperature conditions.Basic parameters
