Whats the deepest vacuum I can pull with an air ejector?
Since most users wish to vent or suck vapors, the maximum vacuum level – which is obtained at the no-flow, or shut-off condition – is usually irrelevant. Using air at 80-100 psig, our off-the-shelf ejectors can pull down to about 10 psia. Other, more expensive, custom built ejectors can pull down to about 3 psia. Two stage ejectors can reach 1 psia.
