ANTI-RIOT FILTER
MISSION
The anti-riot filter is used for the equipment of
filtration systems like the AFU 60. It ensures
the protection of the respiratory system of
the crew members exposed to tear gas.
This filter can be used against the following
gas types:
• 
Phenacyl chloride (CN),
• 
Benzyl bromide,
• 
2-chlorobenzalmalononitrile (CS Gas).
CHARACTERISTICS
This filter is made up of two filtration levels allowing air purification::
• 
the anti-aerosol level includes a paper layer (class U15 according to EN1822) wich allows our
system to reach the P3 protection capacity,
• 
the anti-vapour level includes an active carbon bed wich allows our system to reach the A1
protection capacity.
