AGT-Series Two-Stage Gas Boosters

Two-stage “AGT” boosters provide efficient means of boosting to a high gas compression ratio since the ratio per stage is low. Maximum outlet pressure with these models is drive area ratio multiplied by air drive pressure PLUS supply pressure multiplied by the area ratio of the two gas pistons.

Since these models have interconnected gas pistons, they multiply supply pressure during the “interstage” stroke by the area ratio of the two gas pistons. If supply pressure is too high, the booster may have “interstage stall” at an outlet pressure substantially less than that obtainable on the “outlet” stroke. This limitation does not apply if outlet pressure is less than the “maximum supply” times the area ratio of the two gas pistons.
