CF 6.0″ to CF 2.75″ zero-length reducer

1 × CF 6.0″, 1 × CF 2.75″ (DN40CF) ConFlat flanges, 35.4 cm³ of internal volume and 119.4 cm² of wetted surface.

Build a system with this part

Its internal volume and surface area feed the pumpdown simulation, and its 3D characterization sets how it affects pumping speed.
