1.40 mm RD40 screw thread connection according to EN 148 part 1 2. Combination filter against - 1) first gases and vapours of organic compounds, boiling point > 65°C - 2) inorganic gases and vapours, e.g. chlorine, hydrogen sulfide, hydrogen cyanic acid - 3) sulfur dioxide and hydrogen chloride - 4) ammonia - 5) particle 3. Reusable (R) particle filter component for more than one work shift 4. Passed additional dolomite dust retention test against clogging (so-called "clogging") and therefore marked with "D" Key benefits - All-in-one protection: combines filtration for organic gases and vapours (high boiling point), inorganic gases and vapours, sulfur dioxide, hydrogen chloride, ammonia, and particulates in a single filter solution. - Compatibility and ease of use: RD40 screw thread connection designed to EN 148 part 1, enabling straightforward mounting on compatible respirator systems. - Cost efficiency over time: reusable particle filter component (R) supports longer use across multiple work shifts, reducing replacement frequency. - Reliability in dusty environments: passes the dolomite dust retention test for clogging resistance, and carries the "D" designation for increased performance in challenging conditions. Important attributes - Function: combination gas and vapour filter with integrated particulate filtration - Compatibility: RD40 screw thread connection in accordance with EN 148 part 1 - Size: 1.40 mm RD40 interface - Performance: filtering coverage includes organic gases/vapours with boiling points >65°C, inorganic gases/vapours (eg chlorine, H2S, hydrogen cyanic acid), SO2, HCl, ammonia, and particulates; enhanced by dolomite dust test to reduce clogging Use scenarios - Chemical handling and laboratory work involving organic solvents with boiling points above 65°C, where a single filter offers protection against vapours and particulates - Industrial processes with exposure to inorganic gases and vapours such as chlorine, hydrogen sulfide, hydrogen cyanic acid, as well as sulfur dioxide or hydrogen chloride - Dusty material handling or processing environments (such as dolomite-rich workflows) where clogging resistance improves filter life and reduces maintenance needs Notes - Ensure proper compatible respirator system is used to match the RD40 connection - Replace according to workplace safety guidelines when performance criteria are no longer met or after extended use of the reusable particle filter component
