JW Series

Industrial Ultrafiltration Elements – PVDF 20,000 MWCO

The JW-Series family of ultrafiltration membrane
elements is used for process stream purification
including clarification and removal of large organic
molecules.

The JW-Series membrane is characterized by an
approximate molecular weight cut-off of 20K-50K
daltons.

These elements are bagged dry before shipping.

2

Internal diameter unless specified OD (outside diameter).

3

The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Other pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
