Verified: full wear-and-spare-parts table 0700500901–0700500910 (incl. blower 0700500901 for the EPR-X1), helmet list "Sentinel A-50; Savage A-40; G-30/40/50; F-20", spec-table certification "CE EN12941 TH3 P", battery "Li-Ion, up to 10h @ 170 l/min". Caution: the fact sheet's own body text misprints "EN12942" where the spec table correctly says EN12941 — even manufacturer docs contain errors.
