Bacteria filter
Caution!
The bacteria filter provides additional resistance to the air flow: This can bring
about a change in how the trigger responds. The unit parameters must therefore
be adjusted if a bacteria filter is added later.
VENTIpower
Note
We advise against using the humidifier at the same time as the VENTIpower, as
this considerably reduces the duration of the power supply from the VENTIpower.

Setting up the unit
If BiLevel ST 22 is to be used by several patients (e.g.
in a hospital), the WM 24148 bacteria filter must be
used to protect against infection. It is connected
between the hose system and the BiLevel ST 22 or
VENTIclick. Also refer to the Operating Instructions
supplied with the bacteria filter.
The VENTIpower is available for mains-independent
operation.
VENTIpower can be connected to the therapy unit as
an alternative to the mains supply.
Also refer to the Operating Instructions for the
VENTIpower.
