A diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport high pressure breathing gas as a component of a scuba set. It provides gas to the scuba diver through the demand valve of a diving regulator....
to the same pressure as the scuba diver's surroundings. The breathing performance of regulators is a factor in choosing a suitable regulator for the type of diving to be undertaken, as it indicates the ability of a regulator to meet the demands placed on it at depth and under high breathing loads. It is desirable that breathing from a regulator requires low effort even when supplying large amounts of air.
