This https://www.engineeringtoolbox.com/p...rts-d_134.html gives you the velocities needed for sawdust, etc. Divide the DC capacity by that number gives you the pipe cross section area in square feet; divide that by 144 for sq inches. Use Area = Pi x R squared to see what the ideal pipe size is.

Schedule 40 is the regular pipe. Schedule 80 is extra heavy. The thin pipe is schedule 20.

No, schedule 40 is thinner.
I used black sewer pvc, it less expensive than the white.
Good luck.

I used 4" PVC sewer pipe, I believe it is schedule 20. But much cheaper and lighter and works just as good as the heavier pipe.

Where did you get the schedule 20 pvc pipe at? I can’t find it locally here in Kansas City Missouri.

I own the 2hp Harbor Freight dust collector. For the “average joe” I believe it to be PLEANTY powerful and inexpensive. Love that it is on a cart w/wheels..although not sure how much i’ll be moving it.
Good luck

I think I’ll go this route with a dust deputy and thein baffle. Probably will be just fine for me and run 4” pvc pipe and I’ll get the schedule 40 pipe cause I cannot find schedule 20!

the lightweight stuff is typically in the 'landscaping' section vs. the plumbing supplies - but I'd use the standard sched 40 - you'll have a much bigger selection of fittings etc.

I used sewer pipe and a combination of sewer pipe fittings and sch. 40 fittings to make quick disconnects. Works pretty slick.

Here's a few. If you grind the stop out of the center of a sch. 40 coupler it makes a perfect sleeve to slide over a sewer pipe coupler. I glued some lugs to the outside because it is a friction fit.

"....If you grind the stop out of the center of a sch. 40 coupler it..."
look for a "repair coupler" - it has a smooth 'no stop' bore.
