Cyclone Selector Chart
This chart allows users to quickly chose an appropriate cyclone for measuring PM₁₀, PM₄, PM_2.5, and PM₁ at a range of flow rates.

Cyclone Calculator
This calculator demonstrates the performance of each cyclone determined by a mathematical model extrapolated from actual test data. For each BGI cyclone, users can enter their desired flow rate to determine the resulting D50 cut point. This calculator also provides the estimated pressure drop associated with a chosen flow rate.
