Typical Water Flow Rates²
² The flow and pressure drop characteristics refer to the empty housing only for water at 20 °C (68 °F). For other liquids multiply pressure drop by relative density. To obtain the total pressure drop of a complete filter assembly, the cartridge pressure drop must be added. Please refer to the relevant filter cartridge literature or contact Pall
