The combination filter with Rd40 screw connection is compatible with the Dräger X-plore 6300 and all masks with Rd40 connections. It combines a gas filter (ABEK2 Hg) and a particle filter (P3) to provide comprehensive protection against organic and inorganic gases, sulfur dioxide, hydrochloric acid, ammonia, organic ammonia derivatives, mercury vapor, and harmful particles. The particle filter has the highest protection level P3. The low breathing resistance ensures comfortable wear and allows for unrestricted work without difficulties in inhaling and exhaling. Thanks to the practical screw closure, the filter can be easily attached and replaced, making handling quick and straightforward.
