WaterPro PS Polishing Stations deliver Type I, 18.2 megohm-cm water from the dispensing valve or optional dispensing gun (refer to descriptions for models that include gun) at a typical rate of 1.8 liters per minute depending on feedwater flow rate and pressure, and installed purification modules.

The control panel includes a timed dispense feature that allows unattended dispensing of pure water without risk of overfilling. The dispenser shuts off automatically once user-set time has elapsed.
