The B1P3 filter is used for protection against type B toxic gases according to the EN 141:1990 standard (i.e. organic gases and vapours, toxic particulates and solid or liquid aerosols according to the EN 143 class 3 standard): high filter efficiency (99.95%).
This filter can only be used with a Sperian half-mask.
The half-mask and B1P3 filter set must only be used when the toxic concentration meets the standards for the type of filter used, i.e. when it is below 50 x TLV.
(TLV= TWA for 8 hours of work or STEL for 15 minutes of work)
(cf. INRS document ed. 780 “Respiratory protection devices”).
They can only be used in sufficiently ventilated premises where the atmosphere contains a minimum oxygen volume of 17%.
CHARACTERISTICS :
- Lightweight and resistant plastic housing
- 90 mm in diameter
- Threaded connection to the Sperian half-mask, ensuring a reliable connection and an excellent seal
- Activated and impregnated coconut carbon
- Very high absorption capacity.
GASES TESTED :
- Chlorine Cl2
- Hydrogen sulphide H2S
- Hydrogen cyanide HCN
- The concentration by volume of the test gas is 0.1%
- The tested air flow is 30 litres per minute
- Minimum time required before “breakdown” : Cl2 20 min, H2S 40 min, HCN 25 min.
- Test aerosols
* Paraffin oil for liquid particulates
* Sodium chloride for solid particulates
- The test air flow is 95 litres per minute
- The aerosol penetration for the test must be less than:
*0.05% for sodium chloride
*0.05% for paraffin oil
- Breathing resistance less than:
2.2 mbar at 30l/min
8.2 mbar at 95l/min
