Dräger Aerotest - Quality control of compressed breathing air (EN12021 standard)

Dräger Aerotest systems

The measuring instrument is directly and simply connected to the high pressure air network via a G 5/8 connector. In five minutes, the Dräger Aerotest displays the contamination degree of the breathing air contained in the compressed air flow.

The new Dräger oil impactor specially developed to detect oil aerosols in compressed air is able to measure synthetic oils, regardless of their type and viscosity. The quantitative results are displayed differently.

The EN12021 standard relating to compressed breathing air

This standard defines the quality of compressed air intended for breathable use (outside the hospital environment). It applies to respiratory protection devices (masks, hoods, suits ...) and scuba diving devices:

• Oxygen content = 21% ± 1%
• CO2 content < 500
• CO content < 5 ppm
• Dew point < -11° C
• Lubricant content (mist or droplets) < 0.5 ppm. (the air must have no significant smell or taste)
• Impurities < at the national exposure limit
