GB-H-152-70M and GB-H-152-100M are gas booster packages intended to be used to provide the gas pressure supplies required by controller/calibrators for high pressure gas.

GB-H-152-70M and GB-H-152-100M models include a pneumatically driven, piston type, self-cycling gas booster with regulated output to provide the PPCH-G high pressure supply. The gas booster boosts a lower pressure usually supplied from a bottle, to higher pressure. The high pressure gas is stored in an accumulator volume to assure stable supply to the PPCH-G. GB-H-152-70M has a maximum output pressure of 100 MPa (15 000 psi). GB-H-152-100M has a maximum output of 120 MPa (18,000 psi).
