What is the air vent rate for a working diver?'s?

The air vent rate for a working diver typically refers to the volume of breathing gas that is needed to ensure the diver is receiving adequate air supply during their operations.

In this context, 8 ACFM (Actual Cubic Feet per Minute) is the standard air vent rate used for a working diver. This figure is derived from considerations of the required air volume to support a diver's respiratory needs while accounting for factors such as physical exertion, depth of the dive, and conditions under which the diver operates.

When divers are actively working underwater, they may engage in strenuous tasks that significantly increase their metabolic rate, leading to a higher demand for airflow. Therefore, the industry has determined that an air vent rate of 8 ACFM is generally sufficient to meet these demands without risking hypoxia or other complications related to inadequate breathing gas supply.

While options such as 4, 10, and 12 ACFM exist, they do not align with the standard practices established for diver safety and efficiency during operational tasks, making 8 ACFM the most appropriate choice for a working diver's air vent rate.
