USE 
The term „Particle lter“ means that it contains particle  lter  element 
only. The lter is supplied with a thread connection Rd 40x1/7´´ (EN 148-
1: 2019) or with OZ 40x4 (GOST 8762-75).
THE P3 R PARTICLE FILTER 
type P3 R in combination with a suitable chemical protective mask or lter 
aid with auxiliary ventilation attached to a helmet or hood, the P3 R lter 
forms a perfect protection of the individual against harmful solid and liquid 
particles, biologically solid and liquid aerosols, radioactive aerosols, dusts, 
bacteria and viruses. The lter meets the test against dolomite dust.
ATTENTION!
The lter must not be used:
- against gases
-  against carbon monoxide (CO), carbon dioxide (CO2),  
nitrous oxide (NO) and nitrous oxide (N2O)
- in an explosive atmosphere,
- in an environment with an oxygen volume (O2) less than 17%
ATTENTION!
The real time of use of the lter cannot be determined in advance 
due to a number of factors that affect it. These include, in particular, 
the type and concentration of pollutants, humidity, temperature, flow 
and pulmonary ventilation of the user (working intensity).
PRINCIPLES FOR USING THE FILTER
1.  The user should know the type of pollutants and their concentration 
which the lter intends to protect against.
2.  Visually inspect the lter before using it. The lter must not be me-
chanically damaged. 
3.  Before opening the protective cover of the lter, check that the thread 
marking corresponds to the thread on the mask to which it is to be 
attached.
4.  After opening the protective cover and before using the lter, remove 
the thread cover and the inlet to the lter.
5.  Screw the lter into the mask and, after tting it, check the tightness 
of the threaded connection by clogging the lter inlet with your 
hands. When inhaling, the mask must not be sucked in. 
6.  The lter can be used in the temperature range from - 30 ˚C to + 70 ˚C. 
ATTENTION!
If the user detects an increase in respiratory resistance during 
use, the lter must be replaced.
The lter complies 
with requirements
of the standards  
and relugations:
