N/A. 1  The Hypro D252GRGI is a medium pressure, two diaphragm pump that comes with a 9910-KIT1990 Pressure Regulator and D252 Gear Reduction for attachment to a gas engine with a 3/4 shaft.
The pressure regulator  or reducing valve  fits the yoke of the oxygen tank. It reduces the pressure of oxygen flow from 2,000 psi to levels of 40-70 psi, a safe delivery for patients. Positive pressure devices, or demand valve resuscitators, deliver approximately 60 liters of oxygen per minute in short bursts.
