FFP3 mask 6311 with valve

Highest class for fine and harmful dusts

FFP3 is the highest class under EN 149 and is permitted up to 30 times the workplace exposure limit, like a half mask with a P3 filter (DGUV Rule 112-190). The 6311 is the standard mask for work with fine dust that is harmful to health, where a mask without replaceable filters is enough.

The D in FFP3 NR D stands for a passed dolomite clogging test.

Disposable respirator or half mask with P3 filter?

In dust, both reach the same protection level: 30 times the limit value. The disposable mask needs no cleaning and no filter care and is ready at once. Anyone working in dust for long hours every day is often better served by a half mask AG360 with P3 filters: only the filter is replaced, the mask lasts longer. The comparison helps you decide.

With valve: advantages and limit

The valve makes exhaling easier and reduces heat and moisture under the mask. It does let exhaled air escape unfiltered. Where the surroundings must be protected from the wearer, a mask without a valve is needed.

Limits of FFP3

Above 30 times the limit value, or when eyes and face must be protected, the full-face mask AG700 with P3 filter (up to 400 times) is the right choice. Asbestos, carcinogenic substances and pathogens require additional rules; the selection belongs in the risk assessment. No FFP mask protects against gases and vapours.

Packaging and storage

10 masks per box in a foil bag. Storage in the closed original packaging at room temperature, protected from sunlight, five years if stored correctly.
