• Pressure Drop vs. Liquid Flow Rate: The document includes a graph illustrating clean pressure drop versus liquid flow rate for 10" / 254 mm cartridges, specifying different µm ratings. For liquids with viscosity differing from water, multiply the pressure drop by the viscosity in centipoise. See the official PDF for exact tabulated values.

Ordering Information: Part numbers are available for various removal ratings, nominal lengths, configuration codes, and O-ring materials (including Ethylene Propylene, Viton A, and Teflon Encapsulated Viton). Options exist for prewet configurations. Other O-ring materials are available. See the official PDF for exact part number configurations.
