The Model 74 Low Pressure Booster generates 1500 psi Nitrogen using a 130 psi dry nitrogen source and 85 psi shop air drive. The system consists of a 4 to 1 primary stage pressure booster and a 15 to 1 secondary stage booster. Each pump is controlled by a high flow regulator to set the output pressure of the stage and a drive speed valve to control the rate at which the pump operates.
