High Flow Filter For Etchant Applications

Pressure Drop vs. Liquid flow Rate (Water, 20℃)¹

¹ For liquids with viscosity differing from water, multiply the pressure drop by the viscosity in centipoise

Since etchants can vary significantly, it is recommended that the filter be tested for compatibility at the service temperature to ensure long service life.
