Cascade Impaction: 10 FAQs From the Frontline

The volumetric flow rate of air through a cascade impactor determines the speed at which the air, and by extension particles, flows through the nozzle of any individual stage. Stage cut-off values are therefore a function of volumetric air flow, rather than fixed. This is why test flow rate is important. It needs to be both known and constant.
