How Does Compressed Air Breathing Apparatus Work?
Compressed air breathing apparatus typically consists of a compressed-air cylinder, a carrying system, a pressure reducer, a lung demand valve and a face mask. The pressure reducer lowers the cylinder pressure to the level required by the lung demand valve, which supplies breathing air on demand as you breathe. Because this air supply is independent of the surrounding atmosphere, approved configurations can be used in contaminated or oxygen-deficient atmospheres, and even where the contaminant is unknown, conditions where filtering devices must not be used at all.
Choosing the Right Configuration
Lightweight configurations suit tasks where low weight and easy handling matter most, while an ergonomically designed carrying system improves wearing comfort during longer assignments. The right configuration depends on your application, the required operating duration, the cylinder selected and your breathing rate. Every set includes a warning device that alerts you once cylinder pressure or the remaining air supply reaches a defined warning level. Some configurations can also include an automatic switch-over valve, which lets you switch between an external air supply and the cylinder itself, though this is not a substitute for the low-pressure warning system. For potentially explosive areas, only equipment with the appropriate approval for that environment may be used.
