Protective breathing apparatus is frequently referred to as self-contained breathing apparatus (SCBA), compressed air breathing apparatus (CABA) or simply as breathing apparatus (BA).
Protective breathing apparatus is worn by rescue workers, firefighters or others to provide breathable air in atmospheres immediately dangerous to life or health.
The display instruments from WIKA are installed on the valve of the breathable gas cylinder or on a mobile hand-held instrument. They are used to display the oxygen remaining in the cylinder, so that appropriate measures can be taken in good time. WIKA supplies its products to leading international manufacturers of protective breathing apparatus.
