MSA SSR90 Oxygen Self Rescuer

The MSA SSR 90 is a chemical oxygen apparatus. It supplies the wearer with oxygen which is generated from a chemical (KO2). In a closed circuit the exhalation air of the user is regenerated and enriched with oxygen. The carbon dioxide and humidity of the exhalation air react with the chemical, whereby carbon dioxide is removed, and oxygen is generated. The oxygen is always generated according to the demand of the wearer.

 The MSA Self Rescuer SSR 90 provides 60 minutes of rescue oxygen and up to 5 hours while awaiting rescue.
