Topic tags/keywords: pvc hvac duct dust collection

When it comes time to buy a Dust Collector, one must think of what material to be used for ducting. Lots of pro’s and con’s for HVAC vs PVC. I wanted to share my opinion of why I went HVAC this past week:

1.) All of my HVAC pieces are 26 gauge, not the thinner flimsier 28 or 30 gauge you find at box stores.
2.) I bought all my pieces through a local HVAC distributor. I work on their phone system and do the computer cabling, so was able to get everything at cost, not retail. Example: 6”x6”x6” wye and 5 feet of 6” snap duct cost me under $10 a piece. This was a major deciding factor in going HVAC instead of PVC.
3.) I did have to buy cutting shears, dimple/crease making tool to make female ends, pop rivets and gun, HVAC tape (similar to duct tape), and a 1/2 gallon of grey sealing goop stuff.
4.) HVAC is MUCH MUCH lighter to handle and hang than PVC.
5.) I did not use gloves while cutting and handling this metal. My cuts on the hands can attest to that :)
6.) You can mix spiral and snap duct. The spiral duct is slightly smaller by a hair.
7.) If I wanted to really save $$$, I could of easily went dumpster diving at construction sites to get a majority of pieces.
8.) I am sure, it has taken 4x’s labor & time to assemble HVAC ducting than PVC: cutting, joining pieces, pop rivets, sealing each joint.
9.) There are those that say modifying your duct system in the future is a pain with HVAC, than PVC. I say, not at all now that I know what I am doing and how to go about it.
10.) no static electric shock by touching the ducting :)

Nice job.
It always helps when you can get anything at a contractor dealer. Makes the prices go down significantly.

What’s the hp on your dust collector? Have you done any cfm tests yet on the system?
