Vent Filtration for Soft Drinks Production

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® FRW 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 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, 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.


Emflon PFRW Filter Cartridges
Emflon PFRW cartridges are sterilizing grade hydrophobic membrane filters designed for reliable retention of bacteria and high levels of phages in compressed gas and vent applications.
