Industrial quantitative air filter material filter paper

Industrial quantitative  air filter material filter paper  description:  This HEPA filter paper media is made of glass microfibers as main raw material by wet process. Characterized by uniform fiber distribution, low air resistance, high filtration efficiency, high dust holding capacity, high strength and stable properties. It is an ideal material for air filtration. The products are divided into two types: min-pleat air filter paper and deep-pleat air filter paper, and they have three series: ASHRAE, HEPA and ULPA. Applications This paper is the main materials of air filters. The air filters can be used for air filters of air-conditioning systems in medicine, electronics, food, textile industries and high-grade office/entertainment industries, etc. ASHRAE:for common air-conditioning systems, gas turbines and air compressors.   HEPA :for 100,000 to 10,000 class clean rooms or workbenches, venting systems in nuclear power station, high-grade household cleaners, air purifiers and gas masks, etc. ULPA: for integrated circuit factories and 100 class, 10 class and 1 class clean rooms, etc.   Specification  for air filter paper:
