Description

Description of PTFE Pleated Membrane Filter Cartridges

The PTFE filter cartridge adopts a hydrophobic PTFE membrane with a high flux and long service life. The wide chemical compatibility of the PTFE membrane makes the filter cartridge suitable for various acid and alkali-base solutions, and is widely used in the biopharmaceutical and electronics industries.

The filter cartridge is manufactured in a production facility that meets the ISO 9001 quality system. To ensure that the filter cartridge is clean, its production, testing, and packaging are all  done in a cleanroom

The filter housing, the center rod, and the end cover are made of polypropylene, and the seals of each part are formed by hot melt welding technology.

Advantages

PTFE membrane is the best membrane for acid and alkali resistance
Each part is sealed for hot-melt welding
Hydrophobic polytetrafluoroethylene microporous membranes have broad chemical compatibility
Precise pore size and uniform pore size distribution
Low initial differential pressure, large filtration area, and long service life
High temperature and pressure resistance.

Applications of PTFE Pleated Membrane Filter Cartridges

The sterile exhaust air intake of the fermentation tank, storage tank, batching tank, etc.
