What is the desired maximum overbottom pressure for the MK20 surface supplied diving system?

The desired maximum overbottom pressure for the MK20 surface supplied diving system is 135 PSIG. This specification is crucial because it ensures safe and effective operation during underwater activities. The overbottom pressure is a key parameter in maintaining the correct balance of gas delivery and ensuring that the diver receives the necessary air supply without exceeding safe pressure limits. Setting this threshold prevents potential risks such as over-pressurization, which can lead to equipment failure or diver injury. Maintaining the overbottom pressure at this level allows divers to operate at varying depths while still adhering to safety protocols and operational guidelines.
