High-efficient performance built to withstand demanding conditions
Microbial contaminants can enter the water storage tanks if the tank is not properly protected from the environment. This can lead to contamination of the batch. Pall Emflon® PFRW filters can be used as vent filters to protect the water tanks and holding tanks from contamination by molds, bacteria and other microbial contaminants.
Emflon PFRW filters, featuring two layers of Pall 0.2 micron polytetrafluoroethylene (PTFE) membrane, are designed to protect a sterile tank from the ingress of bacteria, molds and particles, even in the presence of humidity and moisture. All other filter components are made of oxidation-resistant polypropylene. Fully manufactured assemblies are validated by stringent liquid challenge with Brevundimonas diminuta at 107/cm2 filter area and are 100% integrity tested. Emflon PFRW filters are integrity testable by Water Intrusion and Forward Flow tests.
If required, the Emflon PFRW can be protected by a Pall prefilter to ensure long life of the final filter.
