The two-layer structure of this filter material enables the maximum benefit of the surface filtration.
The fine-pored PTFE membrane separates almost all the dust on the membrane surface.
Especially challenging filtration tasks will be solved with a long service life. Polyphenyl sulphide with a PTFE membrane combines very good filtration efficiency with good cleanability. It also boasts good chemical and temperature resistance as well as excellent resistance to hydrolysis.
