Product Features and Specifications
- General Product Information
-
REQUIRES NO LUBRICATION
HIGH FLOW, MEDIUM PRESSURE
REMOTE CONTROL CAPABILITIES
OIL-FREE HIGH PRESSURE SECTION
NOMINAL PRESSURES UP TO 21,250-PSI
AIR OPERATED - DOES NOT REQUIRE ELECTRICITYThis series has the same characteristics of the standard GBT however the double head allows half the input pressure to achieve the same outlet pressure.

(2) Limit maximum gas supply pressure by formula Ps max = factor * Pa to avoid interstage stall
(for example, for gas booster model GBT-15/30 the formula is: Ps max = 15*Pa).
(3) Maximum allowed working pressure for oxygen service boosters: 5,000-psi max.
(4) Maximum allowed working pressure for hydrogen service boosters : 6,000-psi max.
(5) Oxygen & hydrogen service boosters not available on all models. Contact factory for more information.Refer to corresponding gas booster performance curve for operating pressures. Maximum material rated outlet pressures can be reached under special operating conditions. Do not use air drive and/or gas supply pressures that equate to higher outlet pressures than those "maximum material rated outlet pressures" shown on table. Refer to Static Outlet Stall Pressure formula shown on table (for example, for gas booster model GBD-30 the formula is: Static Outlet Stall Pressure = 30*Pa+Ps). Maximum recommended air drive operating pressure: 100-psi. Maximum rated air drive pressure: 150-psi (only for static outlet stall pressure).
