Soft Drinks Vent Filtration

Microbial contaminants can enter the water and product 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 make-up water tanks and holding tanks from contamination by mold, bacteria and other microbial contaminant

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, yeasts, 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 filter can be protected by a Pall prefilter to ensure long life of the final filter.
