Class-1 threaded filters
|
|
|
|
The CE aproval is suspended, production only upon request!
General features:
The Respirator's class-1, EN threaded filter cartridges have metal housing made of aluminium alloy. Their inner structure consists of two different parts:
- Activated carbon which removes the contaminating gases and vapours from the inhaled air in physical and/or chemical way.
- Filtering part made of particular quality paper by folding. This removes the solid or liquid contaminating particles from the inhaled air.
Gas filters contains only the first layer, particle filters only the second one and combined filters contain both.
|
Limitations of use
The filter cartridges can be used if the concentration of the contaminants in the air is not higher than 1000 ppm (0,1 v%) and the oxygen content of the air is 17 v% minimum. The filter cartridges may not be used if the contamination present causes immediate death or permanent injury of health (IDLH).
Design
All types are furnished with colour labels according to the standard as shown by the table attached.
