AIR (PR1) and O(PR2) pressure regulators are employed to regulate the
input pressure to the device. These regulate the input pressure to a level of
approximately 300kPa (44 PSI).
Pressure sensors for AIR (PS1) and O(PS2) are used to monitor the gas
pressure input to be above a minimum operating pressure of 180kPa (26 PSI).
