1Maximum operating pressure and temperature ratings are vessel ratings only. Safe operation will also depend on filter element and seal use. For compatibility details, please contact Pall.
2For applications requiring in-line steam sterilization, please contact Pall for suitable housing series to use.
3For other connection types, please contact Pall.
4Refer to Pall Food and Beverage filter element literature for additional guidelines on use.
5The in-line design of the Pall VFK series vent housing ensures exceptionally low pressure drop. Pall recommends using the gas filter cartridge pressure drop when calculating the system pressure drop with maximum gas flow capacity under actual conditions. For proper vent sizing, especially in the case of pressure or vacuum-sensitive vessels, please contact Pall. Installation of appropriate rupture discs is highly recommended.
