AIRcon Respiratory Humidifier

For ten years, the AIRcon Gen1 stood for therapy with quality of life worldwide. The AIRcon Gen2 humidifier, which has undergone extensive further development, has now heralded the generation change at WILAmed and officially replaced its predecessor on January 1, 2019.

Active humidification redefined

The humidifier AIRcon combines modern technology and innovative design in a high performance unit. Mechanically ventilated patients are provided with optimally conditioned respiratory gas. The humidifier AIRcon fulfills medical requirements as well as economic market expectations. With the humidifier AIRcon, a new overall concept for all patient groups and many respiratory therapies is available. Due to its innovative functions and the optimized accessories, the humidifier AIRcon is perfectly adapted for clinical and extra-clinical use.

Everything from one source

AIRcon provides a complete respiratory humidification system in combination with its specially designed humidifier chambers and breathing tube systems. It is suitable for mechanically ventilated patients requiring individual therapy with high performance and safety.

Operation data

Heating time less than 30 min, typically 10–15 min
Recommended flowrate 1 to 80 L/min
Moisture content > 33 mg/L in the range of 1 to 80 L/min at chamber temperature > 33°C
Maximum operating pressure 200 mbar, unless the instruction for use of the humidifier chamber being used specify lower maximum pressures (1)
Gas leakage of humidifier system at maximum operating pressure smaller than 1 mL/minute (1)
Pressure drop across the humidifier system is typically smaller than 0.3 mbar per m of respiratory tube (22 mm tubing system, humidifier chamber with atomizer) (1)
Internal compliance of humidifier system is typically lower than 5 ml.kPa 1 per m of respiratory tube (1)
Continuous noise is lower than 50 dBa (1m)
Maximum water volume of 500 mL available for vaporization (2)


The humidifier efficiency decreases when the ventilation device is delivering respiratory gas at higher tempera-ture! The temperature of the respiratory gas in the humidifier chamber should be at least 5 °C cooler than the water temperature set in the chamber.
Temperature: from +18 °C to +35 °C (30 °C for NIV operation)
Air pressure: from 70 kPa to 110 kPa
Relative humidity: between 15 % and 95 %, noncondensing
Temperature: from -5 °C to +60 °C
Pressure: from 50 kPa to 120 kPa
Relative humidity: between 15 % and 95 %, noncondensing

Temperature settings (Modes)

IV (invasive operation) chamber 37 °C, close to patient 39 °C
NIV (noninvasive operation) chamber 31 °C, close to patient 34 °C
FREE (freely selectable temperatures) temperatures between 28 °C and 40.5 °C can be selected by the user
Expiratory side heat output can be increased (5 increments) in all modes

Measurement range

Data shown on TFT display
Tolerance for temperature measurement +- 2 °C
