Filter with high absorption capacity against particles
two filters: type a1; according to en 141
The filter is cylindrical (diameter 79 mm) with a black body. The filter consists of
two white fabric filter discs in the inner surfaces.
Application
Ideal for full protection in areas (oxygen concentration with volume above 17%) with contaminated
Gases and vapours with a boiling point above 65°C (e.g. solvents or paint) and organic chemicals.

Filter classes (adsorption capacity)
Each filter also carries an indication of the filter class, as the filters are predominantly divided into three classes (1: low to 3: high) according to their adsorption capacity. The class indicates how much the mak (maximum workplace concentration) may be exceeded.
For gas filters a, b, e and k, the maximum gas concentration in class 1 is 1000 ml/m³ (0.1 vol-%), in class 2 5000 ml/m³ (0.5 vol-%) and in class 3 10000 ml/m³ 1 vol-%). There are different maximum periods of use depending on the maximum concentration and the substance (classification according to boiling point). For protection against group 1 substances, the filter may be used for a maximum of 20 minutes at concentrations of 500 ml/m³ and a maximum of 40 minutes at concentrations of 100 ml/m³. Against substances of group 2 the wearing time is limited to 20 minutes at concentrations up to 5000 ml/m³ and 60 minutes at 1000 ml/m³. For the filters No, Hg, Co and Reactor, the manufacturer's specifications regarding duration of use and concentration must be observed. Filter no may be used for a maximum of 20 minutes, filter Hg for a maximum of 50 hours.
