any restriction at any point on either the feed or out feed side will effect the air movement.
large lines allow more air to move and to move more easily
personally I wouldn't run a line any less than 6". if the tool can only take 4" then look at ways to put larger ports on it or more ports in other areas on the tool.

Hey all, this is my first post! I've scoured the forums for an answer but can't seem to find one so I'm hoping someone knows..
Is it possible to have a 4" inlet with a 6" outlet on a tophat?
Is it better to just transition the 6" piping to 4" (or 2" or whatever) at the tool rather than at the tophat or does it make a difference?
I'm trying to understand what exactly happens to the airflow when one transitions sizes..
Any help would be appreciated! :D
An oversimplification, but the 4" line will have higher velocities and greater frictional losses than a 6" line.
Hey thanks for getting back to me! On Christmas of all days lol
So after a bit more digging I found that the "optimal" pipe size for my DC (Harbor Freight 2HP) is 5". The 5" pipe is going to be too expensive to source for me so I'm left with either 4 or 6..
Given my machine and I'm sure you know its capabilities, do you think it will be able to handle 6" pipe or should I stick with 4"? I'll be mainly using it for fine dust (CNC, table saw)
