AirSave Ultimate

Breathing air quality according to DIN EN 12021:2014

AIRSAVE ULTIMATE I Breathing air quality monitoring, The air quality parameters comply with DIN EN 12021:2014 integrated into the compressor or filling system.

The monitoring (standard version) checks in the compressed air after the filter every 2 seconds with the highest quality and longest lasting sensors (not smart sensors) the content of CO, CO2, O2, water in mg/m3, the temperature, the saturation of the dryer cartridge and controls the compressor accordingly. 

The measuring device can be optionally extended with the following sensors:

NO and SO2 and a sensor for combustible gases


An additional optional variant is the measurement of oil and residual oil mainly in aerosol form in the standard version set to 0.5 mg m³ or 0.1 mg/m³.

Alternatively, we also offer an extremely accurate measuring unit for oils and aerosols down to an oil content of 0.001 mg/m3.

Another option is a second sensor unit, which examines the intake air (ambient air) for CO2, temperature and flammable gases before entering the compressor.

All variants provide the appropriate control of the compressor.

The measured values are stored in the system and can be retrieved as a CSV file via a USB or LAN interface.

A receipt printer, on which the data is printed in order to attach it to the filled bottle, can be supplied as an option.

Only with such a system is it really ensured that the filling system supplies pure breathing air at all times in accordance with DIN EN 12021:2014 and other standards, and that the operator is not exposed to any liability risk at any time.

Scope of delivery: AIRSAVE ULTIMATE integrated into the compressor or for retrofitting.

From now on, we not only measure VOC, but also the residual oil content permanently in the compressed air. A quantum leap! Available only in conjunction with AIRSAVE ULTIMATE.

Filling stations with AIRSAVE ULTIMATE together with a CO2 prefilter enable compliance with the most important parameters of DIN EN 12021: 2014 and other international standards.
