Air Eliminator
Note 2: With only two states returned from the air eliminator, flow must be completely stopped to
purge air.
To purge air by only slowing the rate, a 3 output air eliminator head must be used.
Note 1: When the level drops below Low, the power will be removed from the digital valves, stopping
flow before the air eliminator is completely drained.
