Dust Collection Pipe Questions

[iublue]

Starting to plan my dust collection layout.  I was looking at using Nordfab pipe and fittings.  The consensus seems to be, great stuff but expensive.  I looked on the Grizzly site and they have US Duct.  The US Duct is considerably cheaper.  Like 40% on a 8" by 5' pipe section!!  Does anyone have any experience with either brand?  Are they basically interchangeable?  I know that my new DC is set up for Nordfab.

I like the fact that the metal duct can be changed easily but I was wondering if once I branch off the main truck if the installation would be easier using PVC?  The main trunk will 8".  I will probably have 1-3  8" lines coming off the main.  Once I drop down to 4" for each machine, is it easier to use PVC?

Any other issues that I need to consider?

TIA

Someone has to say it--------------





















be sure to ground the pipes.

IMO there is no reason not to use PVC. Personally the only reason I would use metal ducting is to show off I have some money LOL.

Unless you're using drain pipe (might work, never tried it) the metal pipe I use is about half the price of PVC. I always thought it was the other way around.

Sewer and drain pipe works great.

The fittings are expensive though.

I only checked out of curiosity, but this looks interesting:

Looks like it would be reasonably airtight, especially with taped joints, and smooth enough to offset turbulence common with flex pipe. That's why I use the metal pipe for longer runs.

I would recomend staying away from the flexible drain pipe. The ribs distupt the airflow. It also is very loud from the turbulance.
I used it for direct venting with portable dc unit and drumsander (the dc filter would plug with the fine dust).
It wasn't a fun time.

I've been using 6" PVC for over 24 years and never had a problem. The only issue I've had is once I had a clog in one of the corner turns. Wish I would've use 2 22 1/2 degree turns instead of 1 45 degree turn.

FWIW
