System and method for purging air bubbles from filters

摘要

An air bubble purging system for filters include a venturi valve in the drain line of the filter. The venturi valve is connected to a high pressure source line so that when a high rate of flow is produced in the high pressure source line, a venturi effect is created in the venturi valve to open the venturi valve and produce a vacuum in the drain line so that air bubbles are attracted into the drain line and purged.
