TECHNICAL APPLICATIONS

Sterile filters prevent contamination, from both microbiological particles, dirt particles … of the liquids in storage tanks, coming from potentially contaminated , dirt-bearing or bacterial air.
During the processing phases of stored liquids or when refilling, fluctuations in tank levels generate positive or negative changes of pressure in these tanks with the risk of compromising stability.
For these reasons, atmospheric tanks must be equipped with appropriate safety systems such as rupture discs or vent valves,… as a result, vent filters help to maintain the mechanical stability of the tanks during the filling and emptying phases.

BASIC RULES FOR THE INSTALLATION OF VENT FILTERS

A breather valve or a rupture disk should always be installed on the tanks, both devices intervene in case of blockage of the breather filter cartridge, this is to avoid tank deformation.
When the stored liquids reach high temperatures, it is necessary to apply the steam/vapors originating on the filter body to prevent condensation on the cartridge surface.
In the case of tank steam sterilization, note that it is necessary to flush the filter with sterile air during tank cooling to prevent implosion due to the vacuum generated during steam condensation.
