WFPTFE PTFE Membrane filter cartridge made of PTFE, hydrophobic


WFPTFE Membrane filter cartridges with hydrophobic PTFE membranes are available in filter rations of 0.05 μm to 1.0 μm. The membrane material is highly porous and features a homogenous pore distribution. All construction support-, adapter- and end cap components are made of polypropylene and are thermally connected to the PTFE Membrane in clean rooms without the use of additives or surface-active substances. The filter area of 0.9 m²/10“ cartridge, performs an above average standard compared to similar products. This guarantees a long service life and low differential pressure regardless of high flow rate efficiency.
