Air Treatment Process Evaluation Platform

Test benches under controlled conditions

Different air streams with perfectly controlled inlet conditions (flow rate, humidity, temperature, concentration).



  • Instrumented open gas stream for the evaluation of aerosol filtration processes
  • Instrumented open gas stream for the study of oxidation processes
  • Gas stream for the evaluation of adsorption processes
  • Instrumented closed loop for multi-step process evaluation
  • 1m3 inert enclosure
