K-Flow water absorbing cartridges are used for water and particulate removal from a wide range of petroleum products .With the water absorbing cartridges , particulate removal efficiencies are constant with varying operating conditions . Water retention or absorption is dependent on water concentration . water absorption rate and capacity with vary with each application , depending on the operating conditions of the system . A 718 size cartridge will normally hold 1-3 quarts of water , depending on the three factors , flow rate , viscosity of filtrate and inlet water concentration .Some higher viscosity hydraulic oils, all of the water may not be removed in a single pass. Multiple passes maybe required for total free water removal. For specific sizing and water removal data, please contact us.
