Tightness test
In order to check the facepiece-to-face tightness a leak test must be performed
before each use.
Attention!
If any leakage is detected, correct before using the respiratory fil-
!
tering device.
For persons with beards, long sideburns or scars passing under
the seal it is unlikely that a tight fit can be achieved.
Positive Pressure Test (exhalation):
(1)
Cover valve with palm of hand (see Fig. 5).
(2)
Slowly exhale.
(3)
The mask is tight if it slightly lifts off.
Negative Pressure Test (inhalation):
(4)
Cover both filter openings with palm of hands (see Fig. 6).
(5)
Inhale and hold breath for approx. 10 s.
(6)
The mask is tight if no ambient air enters (facepiece should collapse
slightly).

2.2 Filter replacement

Attention!
Only use undamaged filters of the same type and class.
!
Always replace both filters at a time.
Bayonet filters
Remove used filters and align new filters with opening on face piece and turn
clockwise until the stops are engaged (see Fig. 1).
Use of 20 P2-filter: put particle filter in cover, align cover to gas filter and click-
on. To remove the filters proceed in reverse order.

Filter selection
Applicable National Regulations must be observed. For guidance the EN
529:2005 (Recommendations for selection, use, care and maintenance) is avail-
able.
3.1 Gas and combination filters
Respiratory protective filters are classified according EN 14387:2004, EN
143:2000/A1:2006, GOST 12.4.235-2012, DSTU EN 14387:2006, and marked
with the filter type (code letter and code colour) and filter class (code number).
The filter type, filter class and referenced standard are marked on each filter.
Filter type
Colour
Application
A
brown
Vapours from organic compounds with a boiling
point higher than 65°C.
B
grey
Inorganic gases and vapours, e.g. chlorine,
hydrogen sulphide, hydrogen cyanide
E
yellow
Sulphur dioxide, hydrogen chloride, acid
gases
K
green
Ammonia and derivatives of ammonia
P
white
Against particles of hazardous materials with a
negligible vapour pressure
For the gas filters A, B, E and K, the filter class to be used depends on the possi-
ble maximum concentration of the hazardous gas and the required service time.

Filter classes (code number) EN 14387
GOST 12.4.235-2012, DSTU EN 14387:2006
class 1
1.000 ppm (0,1% vol.)
class 2
5.000 ppm (0,5% vol.)
class 3
10.000 ppm (1,0% vol.)
Important notice: In any case applicable National Regulations
must be observed, especially to determine maximum allowable
concentrations of toxic gases when using filters in conjunction
with half or full face masks.
Always the lowest concentration applies.
3.2 Particle filters
Particle filters are classified according to EN 143:2000, GOST R 12.4.194-99,
DSTU EN 143:2002, in 3 classes: P1, P2, P3 in ascending order of the filter per-
formance.
Important notice: In any case applicable National Regulations
must be observed, especially to determine maximum allowable
particle concentrations when using particle filters in conjunction
with half or full face masks.
Always the lowest concentration applies.
Attention!
When using particle filters against radioactive substances, micro
!
organisms (virus, bacteria, fungi and spores thereof) and bio
chemically active substances (enzymes, hormones), only P3 filters
with full face masks must be used.
The filters must be used only once.
The higher particle filter class includes the protective range (re-
tention capability) of the lower particle filter class when using in
conjunction with the same facepiece. Pre-filters may be used to
prevent premature clogging through large particles (e.g. when
paint spraying), therefore a more frequent replacement of the
Pre-filters may be necessary, if the breathing resistance in-
creases.
The additional marking with "R" (reusable) means, additional tests according to EN
143:2000 were done to verify, that the particle filter or the particle part of combi-
nation filters is qualified for usage after an exposure against aerosols and may be
used for more than one shift. Filter marked with "NR" (not reusable) must only be
used for a single shift only against particles.

3.3 Service time

The service time of respiratory protective filters depends on the conditions of use.
The end of service time of gas filters or the gas filter part of combined filters,
most of the time can be detected by odour on the clean air side. The filter must
then be replaced.
The end of service time of particle filters or the particle filter part of combined fil-
ters, most of the time can be noticed by an increase in breathing resistance. The
filter must then be replaced. Particle filters that have been used against radio ac-
tive substances, micro organisms or biochemically active substances must only be
used once!
4 Storage, Maintenance and Disposal
Attention!
For disposal of filters applicable National Regulations must be
!
observed.
