Adsorption capacity Compounds in the air

Activated carbon has an excellent adsorption capacity for a large number of organic compounds in particular. The adsorption performance of activated carbon is influenced by various factors:

Type of compound to be removed
Concentration
Temperature
Pressure
Moisture

Classification according to TA Luft (Germany)

Carcinogenic substances (C):

Class I: Emission limit 0.5 g/h, concentration limit 0.1 mg/m³
Class II: Emission limit 5 g/h, concentration limit 1 mg/m³
Class III: Emission limit 25 g/h, concentration limit 5 mg/m³

Non-carcinogenic substances:

Class I: Emission limit 0.1 kg/h, concentration limit 20 mg/m³
Class II: Emission limit 2 kg/h, concentration limit 0.1 g/m³
Class III: Emission limit 3 kg/h, concentration limit 0.15 g/m³
