FFP3 NR D, folding mask with inner foam and valve

High-performance FFP3 NR D protection with exhalation valve for cooler breathing during demanding shifts.
Foldable design with inner foam and premium nasal adjustment maximising ergonomics and prolonged comfort.


When the environment demands the highest filtration level, the FFP3 NR D Ref. 31700H provides efficient protection with a superior user experience. Its vertical folded design optimises storage without compromising the seal. The 2.5 cm valve reduces internal heat and humidity, keeping the air cooler and breathing resistance low.
The inner foam and reinforced nasal area, along with the adjustable clip and side tabs, provide a stable, customisable and comfortable fit throughout the working day. Ideal for operations with high particle load where ergonomics and operational continuity are key.
Usage suggestions: construction, sanding and cutting; metal and wood industry; maintenance with the presence of dust, mists and particulate fumes. Combine with proper risk assessment and PPE protocols.
Maximum protection, minimal resistance.

Use cases:
- Construction, demolition, sanding and cutting with high concentrations of fine dust.
- Metal and wood industry (grinding, polishing, machining) with fumes and solid particles.
- Prolonged shifts in hot environments, thanks to the valve and inner foam that enhance comfort.
