Multi-Range Combination Filter DIRIN 500
Description of Multi-Range Combination Filter DIRIN 500
In combination with full face masks, the filter offers you protection against organic gases and vapors
with a boiling point of >65°C, inorganic gases and vapors and particles.
With innovative BIOSTOP and additional testing as NBC protection filter by the German Armed Forces.
Applied standard: DIN EN 14387.
- Organic gases and vapors
- Inorganic gases and vapors
- Industrial materials as well as mercury and toxic dusts
- Bacteria and fungi
The principle of filter respiratory protection is to remove harmful components from the air before inhalation. For this purpose, special filter materials are used, which must be adapted to the pollutants present. Therefore it is important to know which pollutants are present.
Duration of Use:
The service life of the filters depends on the filter class, the environmental conditions (temperature, humidity, pollutant content…) and the breathing capacity of the user. Gas filters are exhausted when the smell or taste of the gas becomes noticeable: Particle filters and particle-filtering half masks when the breathing resistance increases noticeably.
It is therefore advisable to include replacement filters in the calculation, in times of crisis these filters are usually sold out quickly.
Particle filters protect against dust, smoke, spray and mist as well as microorganisms, viruses and spores.
Gas filters protect against gases and vapors, whereby these are divided into several types, and the filters into corresponding types.
Combination filters are gas and particle filters in one.
Multirange filters include several types of gas filters, multirange combination filters combine several types of gas filters and particulate filters.
For classification into filter types and classes, see the following tables:
|Filter type||Main application (type of pollutant)||Classes||Identification color|
|A||Organic gases and vapors with boiling point >65 °C||1,2,3||brown|
|AX||Organic gases and vapors with boiling point <65 °C of low-boiling groups 1 and 2 (see BG regulations)||–||brown|
|B||Inorganic gases and vapors like: hydrocyanic acid (hydrogen cyanide), chlorine, hydrogen sulfide (hydrogen sulfide), but not against carbon monoxide||1,2,3||grey|
|E||Acid gases, such as hydrogen chloride (hydrochloric acid steam) and sulfur dioxide||1,2,3||yellow|
|K||Ammonia and organic ammonia derivatives||1,2,3||green|
|SX||Special gases as indicated on the filter||–||violett|
|NO||Nitrous gases (e.g.: NO, NO2, NOx)||–||blue|
|Hg||Mercury vapor and mercury compounds||–||red|
|Reaktor||Radioactive iodine including iodomethane||–||orange|
