1. Introduction
CleanAIR is a system for airways protection which
®
works on an overpressure basis. The powered respira-
tory unit worn on a belt blows air through a filter and a
hose into a safety hood or a safety mask. The stream
of filtered air forms slight positive pressure inside the
headtop which prevents inleakage of harmful pollutants
from environment air to the breathing zone of the user.
Due to such air supply the user is guaranteed com-
-fortable breathing without having to get over the bre-
athing resistance of the filters.
To ensure efficient protection, it is necessary to choose
a suitable combination of a powered respiratory unit
and protective headtop. It is also important to use the
right filters of the same type.
The powered respiratory unit CleanAIR Chemical 3F
®
meets the standards of EN 12941/A2 and 12942/A2. It
provides protection against non-toxic and toxic particles
and harmful gases according to the filters you use.
2. Instructions for use
Please read the „Manual for use" carefully and follow
the considerations for users. The user must be per-
fectly familiarized with the correct way of using his
protective device and must understand its limitations.
Please read the cautionary instructions and keep them
as reference.
• Oxygen concentration in the working area must not
drop to less than 17%.
• The user must know the kind of contamination and
its concentration in the environment air.
• The powered respiratory unit must not be used in
confined spaces, e.g. closed reservoirs, tanks or
containers, tunnels, canals, ducts.
• It is forbidden to use the powered respiratory unit in
explosive environment.
• Use the powered respiratory unit only if it is swit-
ched on.
• Each time before using the powered respiratory unit
check if the airflow is sufficient.
• If the powered respiratory unit stops working proper-
ly for any reason, the user must leave the contami-
nated area promptly.
• As for the filtration systems with a hood, when the
CleanAIR unit is switched off, the protection of the
EN
airways is small or even none. The increase of car-
bon dioxide concentration and decrease of oxygen
concentration inside the hood is also possible if the
unit is switched off.
• During strenuous work negative pressure might de-
velop inside the hood during breathing in and thus
decrease the protection factor.
• The headtop (either hood or mask) must be proper-
ly sealed to the face to ensure perfect protection.
If long hair or hairs of a beard get into the sealing
line, the inleakage will increase and the protection
provided by the system will decrease.
• Note that the air hose connecting the powered respi-
ratory unit and the headtop can make a loop and can
get caught on protruding objects nearby.
The powered respiratory unit CA Chemical 3F provides
protection against solid and liquid particals as well as
against gases and vapours always depending on the
type of filters you use.
It is vitally important to choose appropriate filters for
different kinds of contamination. Follow the instruc-
tions in the Manual for Using Filters.
• Filters destined for trapping solid and liquid par-
-ticles do not protect the user from any gases.
• Filters destined for trapping gases do not protect the
user from any particles.
• For working environment contaminated by both
kinds of pollution it is necessary to use combined
filters.
• For gases which are difficult to identify it is necessa-
ry to follow special rules.
• Replace the filters whenever there is an odour
change on the air coming into the headtop.
• Use only certified original filters determined for your
powered respiratory unit.
CAUTION! Violation of any precepts for usage of
your powered respiratory unit automatically annuls
the Warranty!
