Does size matter? :D

[bennybmn]

Diameter that is... I've noticed that commercial cyclones are relatively small diameter. Not hose diameter, but the diameter of the ring itself. So do you guys think there is any benefit to a smaller or larger diameter ring in a pre-separator, other than larger waste storage capacity? 

I also noticed that cyclones tend to be conical. What purpose does that serve?

I just figured maybe we could chat about design in general here, instead of detracting from other guys' posts about their own unit.
