Promask / Promask 2
19
With a blower device
The blower must be running
while using the respirator. If the blower turns off by accident, the
device ceases to function as a respirator, and carbon dioxide levels may instantly rise. This is
considered an exceptional situation.
At a very intense working pace, the pressure in the facepiece can change into negative pressure
at peak inhalation.
Protection levels may be reduced if wind speed exceeds 2 m/s.
Filters must not be fitted directly to the breathing hose.

combined filter
The specified multiples of threshold value for the gas or particle filters are
given separately, but in all cases the lowest value applies.
*) Provided that the maximum permissible detrimental gas concentration for the gas filter is not
exceeded. For non-powered filtering devices with gas filter, concentration must not exceed 0.1
vol.% in gas filter class 1 and 0.5 vol.% in gas filter class 2 and 1.0 vol.% in gas filter class 3.
**) If national guidelines exist: in all cases the lowest value applies.
Note!
In Australia only, the following limitations apply:
Provides P3 protection only with a full face respirator (AS/ NZS 1716:2012 refers).
Provides P2 protection with a half face respirator negative pressure respirator
