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 Fluke Calibration GPC1 High Pressure Gas Controller and other high gas pressure test and calibration systems. GB Gas Boosters are intended as high pressure source for calibration and test systems (i.e. high pressure gas controller/calibrators and piston gauges) Hands free and self regulating package - can be mounted out of the way (under a bench or behind a partition) Two high pressure output ranges: - GB-75: pressure up to 10,000 psi (50 MPa) - GB-K-152: pressure up 15,000 psi (103 MPa) 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.
