UltiKleen™ STG Filter

The Pall UltiKleen STG filter is specifically designed for the filtration of organic stripper in non-ashing polymer stripping applications, where the large gel count is high.

The large size of these gels can rapidly plug conventional membrane filters leading to short filter life and process downtime.

The UltiKleen STG filter uses a highly engineered multilayer media construction that combines high gel retention capacity layers with an optimized pleat design for maintaining continuous fluid flow.

The result is superior gel removal and long filter life for extended process operation.
  • Maximum Gel Removal
  • Improved Flow
  • Multilayer Media Design
  • All fluoro-polymer construction
  • 100% integrity tested
  • Prefilter and Final filter grades
