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 

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!
