Abstract
A system for regulating the airflow to a closed environment using feedback control for the position of a control valve and blower speed. The system provides a control apparatus that regulates airflow to a closed environment, such as the mask of a breathing apparatus, to ensure sufficient breathing air for a wearer of such mask. In order to provide fast response to a change in condition in the breathable environment, the airflow regulator includes a valve control and a blower control.
