Description
Fluorodyne II Junior Style filter cartridges are hydrophilic membrane filters designed for reliable retention of bacteria in the final filtration of critical fluids in the food and beverage industry.
Description
The Fluorodyne II filter was developed and validated to provide a secure and reliable removal of microorganisms.
The cartridge is constructed from two layers of 0.2 micron polyvinylidene fluoride (PVDF) membrane. The Junior style configuration is designed to handle small liquid flow rates in compact installations to ensure effective microbial removal.
Fluorodyne II Junior Style filter cartridges are suitable for exposure to repeated hot water and in situ steam sanitization cycles for longer service life.
Microbial Removal Rating
Fluorodyne II Junior Style filter cartridges, passing an appropriate integrity test, provide a sterile effluent when challenged with Brevundimonas diminuta at ≥ 1 x 107 CFU per cm2 of effective filtration area.
