US 2021/0228918 A1 · SUPPLIED AIR RESPIRATOR

Abstract

A supplied air respirator having an airflow path to supply supplied air to a user. The respirator includes a control unit having a sensor located in the airflow path that communicates with a CPU. The CPU also communicates with an indicator that can provide either tactile, audible or visual status indications. One or any combination of these can be used. A power source is provided for powering the CPU and the indicators. The. CPU compares a sensor signal from the sensor with a predetermined operating flow rate and a desired flow rate and indicates to the user the status of the respirator. The CPU continually communicates with said sensor and does not shut down.
