When Respironics upgraded from the 50 Series to the 60 Series, one change made was in the humidifier water chamber lid. Specifically, the older lid has a smaller chamber that projects downward over the heated base, while the newer lid is close to being flat underneath.
Does anyone know exactly what this lid change is supposed to accomplish in the new humidifier design?
I ask because my wife is experiencing severe rainout when using the new 60 Series humidifier in classic mode. We never observed this condition on three prior CPAP/BiPAP units using 50 Series humidifiers in classic mode. We are curious as to whether the change in the lid design is contributing to the rainout problem.
An aside: when the 60 Series's System One mode is "on", the rainout problem disappears -- but so does almost all of the humidity.
Thanks in advance!
I have never had an S50 in my hands, so it can not really contribute to the question.
My humidifier lid has a connector for the Respironics Heated Hose with which rainout can also prevented good in classic mode. Consideration would otherwise procurement of 'Respironics Update Kit' consisting of a lid with the electric connector, the larger power supply (80W) and the heated hose.
You could also use instead the system of the 'Hybernite Rainout Control Heated CPAP Tube', Universal heater hose for most CPAP devices. There should be more similar devices.
Rainout arises primarily from precipitation on the inner wall of the hose from the warm, moist air at much colder room temperature.
