EasyLock® particle filters with bayonet connection can be mounted directly onto the 7000 and 9000 Series mask bodies. They can also be combined with EasyLock® gas filters without an adapter and used as a particle pre-filter.
Particulate filters for respirators offer protection against particles such as dust, smoke and aerosols. They are available in 3 protection levels – P1, P2 and P3. These levels are standardised across Europe according to EN 143:2000 + A1:2006. Particulate filters with a higher protection level offer more effective filtration and can therefore be used to protect against more harmful substances and higher concentrations of contaminants.
Please see below information for use of Filters with Half Face Masks:
P1:
This combination may be used at contaminant concentrations up to 4 times the workplace exposure limit (WEL).
It protects against non-toxic water and oil based particles, but not against carcinogenic and radioactive substances, airborne biological agents of risk groups 2 + 3 and enzymes.
The total leakage permitted by this combination is a maximum of 2%. At least 80% of contaminants are filtered out of the air.
This combination is typically used in environments with low levels of dust not harmful to health.
P2:
This combination may be used at contaminant concentrations up to 10 times the workplace exposure limit (WEL).
It protects against harmful water and oil based particles, but not against carcinogenic substances, radioactive particles, airborne biological agents of risk group 3 and enzymes.
The total leakage permitted by this combination is a maximum of 2%. At least 94% of contaminants are filtered out of the air.
This combination is typically used for handling softwood, metal, plastics (not PVC), and oil mists.
P3:
his combination may be used at contaminant concentrations up to 20 times the workplace exposure limit (WEL).
It protects against harmful and carcinogenic water and oil based particles as well as against radioactive particles, airborne biological agents of risk groups 2 + 3 and enzymes.
The total leakage permitted by this combination is a maximum of 2%. 99.5% of contaminants are filtered out of the air.
This combination is typically used for handling heavy metals, hardwood, brake dust, radioactive substances and pathogens (such as viruses, bacteria and fungal spores). It is also used for stainless steel welding.
