PTFE Membrane Filters
The main application of this membrane filter types is the air/gas-filtration. They are made purely of PTFE and are therefor permanentely hydrophobic. Unlike other (hydrophilic) filter types, they are not wetted by air humidity which allows unhindered passage of air even at low differential pressures. PTFE membrane filter have an excellent chemical compatibility, so that they are also used for the filtration of solvents and acids, to which other filters are not resistent.
