AST - Model PM10, 2 L min-1 -Thoracic Inlet

50% penetration efficiency at an aerodynamic diameter of 10 µm when operated at 2 L min^-1

The penetration efficiency of the PM₁₀ / Thoracic inlet (points) compared to the U.S. EPA definition of PM10 (dashed line) and the ACGIH definition of the thoracic fraction (dotted line).
