Impactors

TImpactors are used to provide information about the size of the sampled aerosol particles. AThe sample flow always passes through a 10 micrometer impactor. Every 6 minutes a valve switches and the flow is sent thorough a 1 micrometer impactor for 6 minutes.

The impactors can be arranged in a rack drawer or in a space within a rack.

The impactor provides a convoluted path for the air to flow through in order to remove particles above a certain size by inertial impaction.
