Pleated PTFE Membrane Filter Cartridge

Main advantages
Using Teflon as filtering material and polypropylene or stainless steel as internal support, the filter-core is welded with good integrality. There are two kinds: Namely natural hydrophobic and amended hydrophilic, and they can be used in filtration of gas and liquid.

It has advantages of special micro-hole structure, good performance, and wide chemical applicability. It can resist strong acid and alkali except Aqua regia, high temperature and ozone. Because of its good biological safety and thermal control, it is an irreplaceable filtering material in lots of situations. Integrality tests are done to all the filter-cores.

Typical application
1. Antiseptic inlet and outlet gas filtration of ferment containers and storage containers
2. Antiseptic filtration of compressed air
3. Cleaning and antiseptic filtration of steam
4. Ozone filtration of mineral water and purified water
5. Filtration of organic solvent
