Breathable Air

Protect yourself from contaminated atmospheres


Breathable air treatment, monitoring, and distribution solutions designed to protect personnel working in environments where the surrounding air cannot be safely breathed without protection.

Breathing Air and Its Regulatory Framework


Breathing air is compressed air that has been treated to protect users when the surrounding atmosphere is polluted or contaminated. Its quality is governed by the European standard EN 12021, which defines the requirements that must be met to ensure a safe air supply for respiratory protective equipment.

What Is Breathing Air?

Breathing air is compressed air whose quality must be suitable for use with respiratory protective equipment when the surrounding atmosphere cannot be safely breathed.


Examples of equipment concerned:

  • Self-contained breathing apparatus, such as the MAR 95 or PK17
  • Helmets, such as the MC91
  • Air-fed hoods

These solutions are used in particular when the environment contains pollutants, contaminants, or conditions that make it unsafe to breathe the surrounding air directly.

EN 12021 at a Glance

The EN 12021 standard defines the main quality requirements that air intended for breathing must meet.


Oxygen

21% ± 1%

CO2

Less than 500 ppm

CO

Less than 5 ppm

Oil

Less than 0.5 ppm

The standard also addresses humidity, dew point, odors, and the presence of other contaminants that may affect the quality of the air being breathed.
