Are you looking for PVC, snap-lock metal, or spiral metal?

Do the spec's for your unit call for 6" duct?
I once helped a neighbour with a 3 hp unit and his only required 4" for average distances. If the line is oversized, the decrease in velocity could cause heavier material to not make the trip to the end of the line.

Hi chifite I am inclined that PVC would be preferrable This is basically I want the 6 inch for the home run and the planer but the other equipment will have 4 inch back to you friend

tawneycocker,
First, please keep all of your questions on this subject in one thread. It will make it much easier on everybody if we don't have to bouce around in multiple threads to keep up with you, and you will get better answers. Do that by clicking on the "Post A Reply" button -- using that "Ask a New Question" button starts a new thread. Thanks.
I agree with Greg posted -- if your collection system is designed to operate with a 4" duct, you may create problems by using a 6" duct on it. If it were me, I would start out using all 4" and smaller ducts, and switch to 6" ONLY if I felt that it would improve the system.

There are some things that will benefit by being oversized. Water supply but not drains and electrical wire are two things that will in a lot of cases benefit by being slightly oversized.
The conduit by which airflow moves has to be carefully controlled to meet the requirements of the application.
Dust collector manufacturers will have this all figured out for you in charts which should be provided with the equipment.
A nozzle or intake will usually offer a restriction where the increased velocity will allow a big chunk of wood to be sucked into the hose. Once the wood enters the hose though, the decrease in velocity from an oversized line will slow down to the point where the hose will constantly plug up.
In your case, smaller is better.
BTW, make sure you install a good grounding system as your instructions will explain.

Dust collections systems, especially those using cyclones are somewhat specialized nowadays.
Here are some things to read about them and the sizing of the piping.
