Product Name: Pocket Filter (HEPA filter)Specification:Material:  synthetic fiber felt   Or fiber glass micron Fiber feltPurpose: can be used as the pre filter in commercial buildings and various industrial ventilation systems, such as pharmaceutical, automotive and food manufacturing industries. Zhenxing® pocket filter using firm, leak-proof design, trilateral sealed to prevent retraction or avulsion. The way of airflow inside the bag is sewing breadth wise, and sealed with a thermoplastic seal gum. Its special structure insures airflow throughout the bag balanced, reduces the resistance and maximize the dust capacity. High air flow, efficiency, and great capacity, long service lifeFiltration class: F5 F6 F7 F8 F9Outside size average effectRate flow volumePrimary resistanceEffective filtration spaceAverage effectBagsW'H'Dm3/hPam2％592×592×6002500/3600/500030/55/1054.64456592X592×5002500/3600/500030/60/1103.86456     592×592×6502500/3600/500045/70/1108.066510592×592×6502500/3600/500045/75/1156.6658592×592×5502500/3600/500050/75/1205.58658490×592×6502500/3600/500090/130/2107.879510Bag filter is made from synthetic fiber, the outside frame is aluminum or stainless steel and plastic.
