Automatic CPAP System with Integrated Hummax Humidification

Providing a good night’s sleep any time, any place
At home or on the road, no need to miss a single good night’s sleep anymore.
With its small size, JPAP provides the same quality treatment everywhere.

Introducing the Natural Support (NS) feature to achieve full comfort 

Our experience of more than thirty years providing breathing support to ICU patients allowed us to develop Natural Support (NS).
NS allows the user to set different support levels during inhalation and exhalation, maximizing comfort in any condition.
