QualityMix Light – The basic _O2/AIR blender for all requirements. Reduced to the essentials, without compromising on precision. A two-chamber mixing system for oxygen and compressed air that delivers what it promises. Like its big brother QualityMix, the QualityMix Light also regulates the set value between 21 % and 100 % oxygen content precisely and quickly – with 2 outlets and ABS housing, but without the monitoring option of an attached oxygen monitor.
