MOUDI Mehrdüsenimpaktor

The MOUDI Impactor Model 100 and 110 are 8-stage and 10-stage cascade impactors with rotating impaction plates to provide near-uniform particle deposits over a circular impaction area approximately 25 mm in diameter.

The flow rate is 30 l/min and the cutpoint diameter range from 10 µm for the first stage to 0,056 µm for the last stage in the 10-stage impactor. A 15 µm pre-impactor forms part of the inlet system and the particle deposit for this pre-impactor is also available for analysis.

Together with the final filter, the impactor provides a complete size distribution measurement for particles in the 0 .. 15 µm range.
