Criteria for the selection of filter apparatus sets
(according to DGUV-R 112-190)
Tabelle 2: Range of filter devices
Filter apparatus set
Half mask/quarter mask with P1 filter
Half mask/quarter mask with P2 filter
full face mask with P2 filter
Half mask/quarter mask with P3 filter
4)
ter
full face mask with P3 filter, gas filter
1)
For filter apparatus sets with combination filter the most stringent respective multi-
ples of the limit value for the gas or particle filter element apply in each case.
2)
Modifications may be possible due to national regulations.
3)
For Australia and New Zealand (SAI Global) the following applies: P3 filters only
offer a P3 protection in combination with full face masks. With half masks they offer
a protection like P2 filters with no limitation of use.
4)
Provided that the maximum admissible usage concentrations of 1000 ml/m3 (0.1
vol.%) in relation to the gas absorption in gas filter class 1, 5000 ml/m3 (0.5 vol%)
in gas filter class 2 have not already been exceeded.
