The in-stack Cascade Impactor is a seven stage jet filter assembly that removes particles by diameter. It is able to filter from 17 to 0.2 microns in eight size classifications and is unaffected by moisture. The pre-cutter assembly allows the cascade impactor to be used horizontally, meaning it can attach to nearly any standard assembly. The pre-cutter includes six nozzles (1/8", 3/16", 1/4", 5/16", 3/8", and 1/2") to ensure correct flow rates.

• 7-stage cascade impactor for particle size distribution of stack particulate matter
• 47 mm filter outlet with Viton® O-Rings and foil collection plates
• PRA-K stainless steel pre-collector with set of six interchangeable nozzles (1/8" to 1/2")
• Complete CI-701K kit with impactor, pre-cutter, nozzles, tubing and glass fiber filters in a carrying case
• WINCIDRS software calculates each stage's aerodynamic cut point and DP50 for particle size reduction
• PM-2.5-10C software option for simplified PM10 and PM2.5 cyclone data reduction
