The market of adsorption filters for the removal of gaseous pollutants for HVAC applications and compressed air processing has grown over the last years. Reasons for the increasing request of HVAC adsorption filters are amongst others the augmenting use of air conditioning systems and the increased public awareness of indoor air pollutants. However, the use of adsorption filters in these two fields of application is still falling behind the use of particle filters and the same applies for the extent of research and development. The number of published research articles is significantly lower for adsorption than for particle filters.

Thus, in a current research project, the separation processes of adsorption filters for HVAC and compressed-air are investigated with regard to adsorption capacity and energy efficiency. The results are used to determine characteristic numbers evaluating the relation between separation performance and energy efficiency and to develop classification systems. These can be used by industry as a basis for a possible definition of energy labels.

Selected results are presented of the investigations on the capacity of different filter types for the two different applications...
