YT-74981 anti-dust respirators in protection class FFP2 with an exhalation valve. The four-layer structure is a combination of internal working layers, i.e. a filtering and a special layer for hot air, thanks to which a minimum amount of moist air is deposited on the half-mask, and external layers improving the comfort of use and mechanical strength. Half masks with an exhalation valve facilitate the evacuation of air and will prove themselves during the performance of strenuous physical effort.

protection class: FFP2
quantity in the package: 5 pieces
The four-layer construction combines comfort of use with durability:

skin-friendly layer -> hot air layer -> filter layer -> outer layer with increased tear resistance
YT-74981 half masks have been tested by an accredited Notified Body in the EU and obtained the CE certificate based on the EN 149: 2001 + A1: 2009 standard.

PROTECTIVE CLASSIFICATION:

Certified respirators protect the respiratory tract against dust, smoke and fog (aerosol), but not against steam or gas. In some workplaces, they may be obligatory equipment for an employee, but one should not forget about the threats to our health present during domestic or hobby work, e.g. when sanding walls, working with wood, cleaning the chimney, etc. FFP from English Filtering FacePiece should be translated as a filtering half mask followed by a number from 1 to 3 defines the degree of protection. Both the name and the detailed description of the protection levels are described in the European standard EN 149 and in a telegraphic shortcut it should be assumed that the higher the number means the higher degree of filtration.

FFP1 – they filter up to 80% of airborne particles up to 0.6 μm. It can be used where the TLV * value is not exceeded more than 4 times. Most often used in the food and construction industries.
FFP2 – they filter up to 94% of airborne particles up to 0.6 μm. It can be used where the TLV value is not exceeded more than 10 times. They are most often used in the metal industry and mining, where the presence of harmful aerosols, mists or fumes in the air is the order of the day.
FFP3 – they filter up to 99% of airborne particles up to 0.6 μm. It can be used where the TLV value is not exceeded more than 30 times. Most often used in the chemical industry. They deal with smoke, aerosol particles as well as radioactive, carcinogenic and pathogenic substances such as viruses, bacteria and fungal spores
* NDS, i.e. the maximum permissible concentration, is a parameter resulting from measurements performed in the workplace. It informs the employer about air pollution resulting from production / work and about the potential consequences for employees staying in the examined room.
