Particle filter
Combined filter
Filters are marked, according to their scope, through letters and colours indicating their type and through numbers indicating their
class. The combined filters are marked in accordance with gas and particle information.
Filter type Class
A 1, 2 or 3
Note the specific
AX
Instruction for use

Class 20, 60 o 180 is the maximum time for filter use in minutes.
The following special filters: (special instructions for use must be followed for CO and REAKTOR filters)
CO P3 Black/White
Hg P3 Red/White
NO P3 Blue/White
REAKTOR P3 Orange/White
The A, B, E and K gas filter class to be used depends on the maximum possible concentration of harmful gas in the atmosphere
during use and on the limits of protection, below described, for the same toxic substance. The time required for the operation must
also be taken into account. particle filters have, according to their class, a different filter capacity and they must be chosen taking
into account the level of hazard and toxicity of the particles to be filtered as well as the above-mentioned limits of protection.
Combined filters must be chosen taking into account type and characteristic of the gas and particles present in the atmosphere. in
case of doubt, that is to say when it is no possible to determine the relative presence of toxic gases and particles, a combined filter
must be used for safety reason.
Note: Filters heavier than 300 grams cannot be connected directly to half masks or quarter masks. Filters heavier than 500 grams
cannot be connected directly to full face masks or any other mouthpiece (see table related to filter code numbers). Heavier filters
must be equipped with a portable device allowing them to be connected to the mask by a hose.
Offer protection against harmful particles and aerosol, but they do not protect
against gases;
Offer protection against harmful gases, particles and aerosols.
