The positive side effect of the air washer, the washing out of the air, is used here as the main goal. 

Solid and gaseous compounds such as fine dust, pollen, spores (allergens) as well as sulfur oxides, nitrogen oxides and ozone are absorbed to a large extent. The air washer is not only used to wash out NH3, but also as an AMC filter stage in clean rooms in semiconductor production. 

Multi-stage air washers are always used when there is a very high level of air pollution and at the same time almost complete washing out is to take place. In this design, washing out takes place through several washing stages in combination with various additional components such as intermediate separators or packing. A customer-specific design is based on the requirements specified by the customer.
