PTFE filter cartridge

Detailed Product Description

Main advantages

Using Teflon as filtering material and polypropylene or stainless steel as internal support, the filter-cartridge is thermally 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-cartridges.
