The Drager Rd40 Combination Filters have a single-thread connection in accordance to EN148-1. For more information on the types of gases the filters protect against read the Drager Safety guides by Application or by Gas and Vapour type.


The A2P3 R D combination filter from Drager Safety is part of the X-plore Rd40 filter range. It’s specifically for use against gases and vapours of organic compounds with a boiling point of > 65 °C.
It can also offer protection against dust and particulates (99.95% efficient).

It’s also approved as a filter TH/M3 A2B2 P SL R (EN 12941/12942) for the Drager X-plore® 7500. It has an Rd40 thread connection which is standard in accordance to EN 148-1. This means it can be used with certain Drager half and full face masks including the X-plore 6300.

It’s important to note that although Drager term the filter as being reusable this will depend on a number of factors. Factors include breathing rate, the atmosphere, humidity and temperature will affect the lifetime of the filter. This means the lifetime will vary amongst users and applications.
