Sundstrom SR294 Gas Filter ABE2

Package
8 items left


SR 294 ABE2 are for use with Sundström half and full face masks and protects against organic compounds with a boiling point above 65°C, inorganic and acid gases/vapours, i.e.


  • Type A protects against organic gases and vapours, such as solvents, with boiling points > +65 °C.
  • Type B protects against inorganic gases and vapours, such as chlorine, hydrogen sulphide and hydrogen cyanide.
  • Type E protects against acidic gases and vapours, such as sulphur dioxide and hydrogen fluoride.



Tested and approved according to EN 14387:2004, AS/NZS 1716:2003

Model:  H02-3312  


 



The following are all indicators that its time to replace your filter:


  • The expiration of the service life of gas filters can be detected by odour or tasted on the clean air side. The filters must then be replaced.
  • The expiration of the service life of particle filters or combined filters that are used against particles can be detected by an increase in inhalation resistance.
  • With combined filters – depending on the predominant protective function – both criteria must be observed. Particle filters must only be used once against radioactive contaminants, spores, bacteria,viruses and proteolytic enzymes.
  • Some filters have a specified maximum service time (CO filter cartridges, combined filters 93 Hg/St) or they have an incorporated warning system (CO filter canisters).
  • Filters that are used against hazardous gases whose infiltration cannot be detected by odour, taste or irritation, are subject to special regulations concerning duration and usage that depend on the conditions of use. Otherwise a form of protection that functions independently of the ambient air must be used.


Further conditions of use in each individual workplace and of each user affect the service life of respiratory devices, such as:


  • Pace of breathing – the higher the rate of breathing the higher the contamination rate of the filtering device
  • Temperature of the ambient air – the higher the temperature, the shorter the service life
  • Humidity – the higher the humidity the lower the intake capacity of activated carbon against organic gases and vapours
  • Mixtures of hazardous agents – less absorbent components in the activated carbon can be replaced with components that offer higher rates of absorption (desorption)


For factory sealed and properly stored gas and combined filters the following storage lives can be expected:


Filters type A, AX, B, E, K, Hg, Reactor : 6 years
Filters type CO, NO : 4 years


Proper storage conditions are indicated on the filter packaging. The expiration date is marked on the individual filters. Gas and combined filters that have been opened must be replaced after 6 months at the latest*, or earlier if they are exhausted..
