* Edwards EH Series boosters feature our unique hydokinetic drive which provides significant cost and performance advantages over direct drive machines. The hydrokinetic drive removes any need for pressure sensors or bypass lines or inverters, and allows the booster to run from atmospheric pressure to ultimate vacuum, giving faster pumpdown and more flexible operation with less maintenance.
