DFPS

Asymmetrical Polyether Sulphone Membrane Filter
Since DFPS is made of non-symmetrical polyester sulphon membrane, it can provide high porosity rate, long life and high flow rate. Desired specific resistance is obtainable by use of limited rinsing because eluted substance is very limited. DFPS is effective for such applications as ultra-pure water making and sterilization of process water.

Materials of Composition	Hardware / Polypropylene, Media / Polyether Sulphone / Support / Polypropylene, Center core / Polypropylene
Filtration Precision (Absolute microns)	0.04, 0.1, 0.2, 0.45, 0.65, 0.8
Dimensions	Outside diameter: 70mm Inside diameter: 30mm Length: 10, 20, 30, 40 (inch) / 250, 500, 750, 1000 (mm)
