2.13.2 Pressure
regulator
The pressure regulator (4) is a non-relieving pressure regulator that regulates high
pressure filtered supply gas down to 172 kPa (25 psi).

2.13.3 Flow
control valve
The flow control valve (5) is controlled by the CPU. Signals are sent to the flow control
valve of the necessary flow determined by ventilator settings and sensor signals. The
flow control valve modulates the incoming 172 kPa (25 psi) drive gases to an output
from 0 to 120 liters per minute at pressures ranging from 0 to 100 cm H
