Hi All,
I've had dust collection on the brain for awhile, thinking of ways to pick one up used and modify it into a 2 stage one for my small shop. Most of these I find are 1-2hp, usually about 1.5. In thinking of how to get the most efficiency out of the motor I've always had the question as to why we tend to run 4-5inch piping for dust collection systems? Wouldn't thinner piping equate to better suction on the end of the run? I get a lot of tools use 4 inch fittings, but expansion fittings are easy to adapt and it would still seem to me that you'd get more power with a thinner pipe line. And that doesn't explain the 5 inch piping to me. Obviously 4 and 5 are the standard out there so what am I missing in all of this?
Thanks all.
