Product Description

REQUIRES NO LUBRICATION

HIGH FLOW, MEDIUM PRESSURE

REMOTE CONTROL CAPABILITIES

OIL-FREE HIGH PRESSURE SECTION

NOMINAL PRESSURES UP TO 12,500-PSI

AIR OPERATED DOES NOT REQUIRE ELECTRICITY

This series has the same characteristics of the standard GBT however the double head allows half the input pressure to achieve the same outlet pressure.

(1) Coned and threaded high pressure connection for 1/4 "OD tubing.

(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).

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).
