Graseby Andersen Mark III Eight Stage Cascade Impactor

A multi-stage, multi-jet impactor for stack particulate effluents in moderate grain loading applications. Andersen's impactor is made of stainless steel with Inconel O-rings and is able to withstand temperatures of 1500° F, if used without special collection substrate and back-up filter. If your application requires a substrate filter, the impactor will only withstand temperatures up to approximately 800° F. The gooseneck inlet nozzle and internal high capacity preimpactor fit through a minimum 3" port.  CleanAir Analytical now offers tared Andersen impactor substrate sets and full post analyis.

Helpful Hints

Helpful Hints: 
Our experience shows that the Mark III Eight Stage Impactor can be operated without the use of the cross hairs as long as no backflow of gas through the probe occurs-which would destroy any sample.The cross hairs can introduce more error due to substrate sticking. Substrate sets are available from CleanAir.
