The pre-filter cover allows the combination of particle filter X7N11 P2 R D with absorbers X701 A1, X702 A1E1, X703 ABEK1. Such a set extends protection beyond gases and vapours to dust protection. Can be combined with absorbers X701 A1, X702 A1E1, X703 ABEK1 and thus used with half-masks X6 and X7 series and full-face masks X8 series.
