ABSTRACT:
A single stage impactor having a plurality of different sized nozzles that predicate a particle collection efficiency curve that approximates a predetermined curve. The impactor has a particle collection plate mounted on a casing having a passage connected to an air moving device. A nozzle plate having a plurality of different sized nozzles is mounted on the collection plate. The nozzles can be round, rectangular, or a combination of round and rectangular. The sizes of the different nozzles are coordinated with the pressure drop across the nozzle plate to provide the nozzles with different particle collection cut-off characteristics. The combined collection efficiency curve or penetration curve of all of the different sized nozzles approximates a predetermined curve, as a respirable particle penetration curve.
