Andersen Eight-Stage Impactor (ACI)

• The ACI utilizes eight size-separation stages enabling classification of aerosols from 9 µm to 0.4 µm (at 28.3 lpm) and allows airborne particulate to impact upon stainless steel, glass, or a variety of filtration media substrates. 
• A final filter collects all particles smaller than 0.4 µm.
