Introduction

CleanAIR is a system for airways protection which
works on an overpreassure basis. The powered
respiratory 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 positi-
ve pressure inside the headpiece 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
breathing resistance of the filters.
To ensure efficient protection, it is necessary to
choose a suitable combination of a powered respi-
ratory unit and protective headpiece.
It is also important to use the right filters.
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.
See picture index for a list of headpieces.
The powered respiratory unit CleanAIR CHEMICAL
2F meets the standards of EN 12941, EN 12942. It
provides protection against non-toxic as well as
toxic particles and harmful gases according to the
filters you use.

Instructions for use

Please read the „Manual for use" carefully and
follow the considerations for users. The user must
be perfectly 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%.
______________________________________________________________________________
Content
:
• 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
properly for any reason, the user must leave the
contaminated area promptly.
• As for the filtration systems with a hood, when
the CleanAIR unit is switched off, the protection
of the airways is small or even none. The increa-
se of carbon 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
develop inside the hood during breathing in and
thus decrease the protection factor.
• The headpiece (either hood or mask) must be
properly sealed to the face to ensure perfekt pro-
tection. 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
respiratory unit and the headpiece can make a
loop and can get caught on protruding objects
nearby.
The powered respiratory unit CA Chemical provi-
des protection against solid and liquid particals as
well as against gases and vapours always de-
pending on the type of filters you use.
It is vitally important to choose appropriate filters
for different kinds of contamination. Follow the in-
structions 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.
