The professional replacement filter filters organic gases and compounds as well as vapours with boiling point above 65°c, inorganic gases and vapours e.g. chlorine, hydrogen sulphide, hydrogen cyanide, sulphur dioxide, hydrogen chloride and other acid gases, ammonia and organic ammonia derivatives. The replacement filter is very light. The matching respirator is also available in our shop.

Filter classes (adsorption capacity)
Each filter also carries an indication of the filter class, as the filters are mainly 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.
