Steam Cleaning Lenticular Pak® Filters
Stainless steel filter housings must be cleaned prior to installation of depth filter media or Zeta Pak® lenticular cartridges to remove any residual contaminant, including residues from prior use. This includes but is not limited to O-ring grooves and O-rings and threads. Refer to your in-house validated cleaning procedures. A vent valve should be installed at the upper most connection or at the top of the housing in order to expel air at the start of steaming and during introduction of the process liquid. A pressure gauge for monitoring steam pressure should be installed on the filter assembly.
