Dräger Rd40 940 A2B2E2K1 P2 RD Kombinationsfilter 6738803

This Dräger combination filter is built for demanding industrial environments where protection against multiple gas types and particulates is required. Its Rd40 thread fits a wide range of Dräger X-plore masks, and the RD marking confirms dolomite dust testing for extended reuse.

Highlights

• Broad protection: A2B2E2K1 gas classes plus P2 particle filtration
• Rd40 standard thread (EN 148-1) for secure mask connection
• Reusable design with dolomite dust test (RD)
• High capacity for organic, inorganic, acid gases and ammonia

In daily use

The filter handles organic vapours above 65°C boiling point, inorganic gases like chlorine and hydrogen sulphide, acid gases, and ammonia derivatives. The P2 rating filters solid and liquid aerosols at 94% minimum efficiency. Operating range spans -30°C to +60°C, and the high-impact plastic housing withstands rough handling.
