There is a differentiation between:
- Industrial breathing air
(normally according to EN 12021 – respiratory equipment – compressed gases for respiratory protection devices)
Specifications for water content (H2O), lubricants (oil), carbon dioxide (CO2), carbon monoxide (CO) and oxygen (O2)
- Medical breathing air
(Pharmacopée Européenne / Pharmaceutical law)
Specifications for water content (H2O), lubricants (oil), carbon dioxide (CO2), carbon monoxide (CO), oxygen (O2), nitrogen oxide (NOx) and sulfur dioxide (SO2)
In order to produce breathing air the application of catalysts is necessary in addition to normal treatment processes. Catalysts are not resistant to moisture – which is why compressed air needs to be dried by an adsorption dryer first.
