LOFMEM TFA

LOFMEM TFA membrane filter cartridges uses absolute rated PTFE membrane combined with PTFE support layers and PFA hardware to create a fluoropolymer pleated cartridge filter suitable for use in the most demanding environments. LOFMEM TFA is manufactured without the use of glues, adhesives or wetting agents, ensuring high purity in every application.

Absolute rated PTFE membrane filter cartridges are designed to resist the most severe chemical exposure environments, making them the preferred choice for demanding high temperature and chemical process applications. LOFMEM TFA is designed for use with strong acids, bases, organic chemicals and oxidizers.
