this series of pocket filter / HEPA Filter using firm, leak-proof design, trilateral sealed to prevent retraction or avulsion. The way of airflow inside the bag is sewing breadthwise, 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 life
Filtration class: F5 F6 F7 F8 F9

Bag filter is made from synthetic fiber with density gradually increased imported from US, the outside frame is aluminum or stainless steel. Satisfactory filtration material, and ideal milling process treatment, solid structure are the main features. Bag filter series with various filter effect (EN 779 standard) from primary G3 to middle –high F8, mostly 6 bags or 8 bags types. It is widely used in electronics, pharmaceutics, mechanic & instrument, metallurgy ,petrochemical, chemical, light industries.
