Open circuit sets are filled with breathable compressed air that lasts for 30 60 minutes.
The closed circuit type also known as a rebreather operates by filtering supplementing and recirculating exhaled gas.
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user s exhaled breath to permit the rebreathing recycling of the substantially unused oxygen content and unused inert content when present of each breath.

It is used when a longer duration supply of breathing gas is needed such as in mine rescue and in long tunnels and going through passages too narrow for a big open circuit air cylinder before open circuit scba s were developed most industrial breathing sets were.
You need a closed path or closed circuit to get electric current to flow.
Closed circuit synonyms closed circuit pronunciation closed circuit translation english dictionary definition of closed circuit.
This differs from open circuit breathing apparatus where the exhaled gas is discharged directly.
If there s a break anywhere in the path you have an open circuit and the current stops flowing and the metal atoms in the wire quickly settle down to a peaceful electrically neutral existence.
It connects to the scba by a strap this does connect to the regulator that supplies the air to the body wearing in.
