QualityMix air-oxygen mixer

QualityMix air-oxygen mixer

The QualityMix air-oxygen mixer is designed for continuous and precise medical administration of air and oxygen to babies, children and adults.

The accurate fractional inspiratory oxygen content (FIO2) of the QualityMix corresponds to the FIO2 setting selected by the control (rotary knob). The device is suitable for patients who have difficulty receiving sufficient oxygen from the ambient air.


The Qualitymix base model is a low-pressure mixer. It is a modular system consisting of a two-chamber oxygen and compressed air mixing system. It is accurate and fast (+/- 2 % deviation over the whole measuring range). The mixer adjusts the set oxygen concentration on a scale of 21-100 %.


Key features:

  • Mixing ratio range: 21-100% (+/- 2%)
  • Free outlet flow: up to 30 litres per outlet
  • Pressure control module: inlet 3,5-6,5 bar, outlet to mixer 3,5 bar
  • Basic model with either one or two flow meters
  • The air valve can reduce noise and gas consumption
  • Pressure equalizer module ensures a steady flow regardless of inlet pressure
  • Oxygen meter module
  • Holder module for portable oxygen meters
  • “Blender buddy” attachment that connects to the blender, with two flow meters and a separate oxygen meter
