Does the Last Chance Rescue Filter Unit have an air supply?

The Last Chance Rescue Filter Unit is an air-purifying respirator that does not contain an air supply. It is designed to be connected to a Self-Contained Breathing Apparatus (SCBA) in the event of an out of air emergency or equipment malfunction. It protects an individual’s respiratory system from the effects of smoke and toxic gases for up to 15 minutes during an escape from an emergency situation. When you breath through the filter, the incoming air is cleansed. Toxic gases typically found in smoke from fires, are absorbed or converted.
