What is the flowrate of the oxygen pressure reducer in a BG4 system?

In a BG4 system, the oxygen pressure reducer is designed to regulate the flow rate of oxygen to ensure that the user receives a consistent and adequate supply while operating in an environment where breathing air is compromised. The correct range of 1.5 - 1.9 liters per minute allows the wearer to breathe comfortably and effectively while also maintaining safety and efficiency.

This specific flow rate is crucial for maintaining the right balance between available oxygen and the demands of the user during physical activity in potentially hazardous situations, such as mining environments. Other ranges are not suitable because they do not provide the necessary oxygen supply for the physiological needs of the user under conditions where the BG4 system is typically employed.
