PRODUCT OVERVIEW
GB-75 and GB-152 are gas boosters with control kits intended to be used to provide a very high pressure
gas supply to systems using a GPC1 High Pressure Gas Controller and other high gas pressure test and
calibration systems.
Both models include a pneumatically driven, piston type, self-cycling gas booster. The gas booster
boosts a lower pressure, generally supplied from a bottle (2 MPa [300 psi] minimum), to higher pressure.
The booster is powered by drive air. The high pressure output is equal to the drive air input times the
boosting ratio of 75 or 152. The high pressure output is connected to the SUPPLY port of a GPC1 or
other system to which high pressure gas is to be supplied.
Both gas booster models include a drive air control kit and interconnecting tubing. The kit is on a bracket
that can be mounted at a convenient location remote from the booster itself.
GB-72 and GB-152 are not a good choice for supplying pressure to a PPCK+ high gas pressure
controller/calibrator. A different model, GB-K-75 and GB-K-175, with features specifically intended to support
PPCK+ is available for this application.
