Micropak WF Filter Elements

Summary

Product identification

The MICROPAK™ WF Series Filter Elements are coreless filter elements featuring highly asymmetric polysulfone media. They are designed for use with reusable Micropak cores, offering an environmentally friendly, waste-reducing design. These filters are absolute rated at >99.9% efficiency with retention ratings from 0.05 to 1.2 microns (µm), providing superior flow rates and long service life. They utilize a pressure-energized gasket-to-core sealing system.
