The pre-formed and elastic support makes an easier and reliable fit to all kinds of faces. It offers an excellent visual field and great compatibility with glasses.

Intelligent exhalation valve

Narvalo Active Shield is the innovative air extraction valve for FFP3 masks developed by Narvalo, a start-up and spin-off from Politecnico di Milano, with BLS and POLIHUB. This intelligent valve ensures optimal breathing comfort, thanks to an adaptive fan that reduces humidity and extracts CO2 ensuring maximum freshness during use.

Lithium battery
This valve is equipped with a rechargeable lithium battery (800 mAh) that gives the device more than 8 hours of autonomy. The recharging socket is a micro USB located on one side of the product.

Adaptive ventilation
The adaptive ventilation system extracts the CO2 produced during breathing and reduces the moisture accumulated inside the mask. The ventilation is adjusted automatically and adapts to the user's breathing.

Armor® layer
It is an external protective layer that ensures the protection of the filtering material from dirt, dust and liquids as well as the normal mechanical stress due to prolonged use thus extending and preserving filtering efficiency and making the device safer.

Made with a new soft technical foam, which allows an excellent fit on any face and guarantees a high comfort on contact with the skin.

The nose clip, placed internally between the layers of filtering material, adapts optimally to the profile of the nose and eyes, ensuring good visibility and maximum compatibility with glasses.

Adjustable elastics
The elastics, thanks to the innovative drop-off system, facilitate the correct positioning of the facepiece on the user’s face.

Available with activated carbon
An activated carbon layer may be added to the respirator to protect from nuisance odours caused by gases and vapours, both organic and acidic, including ozone (ideal for welding operations), in concentrations below the threshold limit value (TLV).

It breathes!
The ratio of transmission of water vapour through the material is 4500 g/m² * 24hrs. A value that defines materials of a high transpiration range which makes it ideal for hard physical work.

Single pack
It allows maintaining a high level of hygiene.
