Thread: Dust collector pipe sizing

  1. #16
    The ducts I plan to use are these:

    They've been used by plenty others to build their own DC systems so I think it should be alright.

    Dennis, I have spiral pipe in my shop as well. Only downside I can see, is you have to use couplings that fit inside the pipe to attach your fittings and joints. With snaplock pipe, the ends of the pipes are crimped and fit inside the pipe it joins to. You can orient the crimps so the air flows through the crimp toward your dust collector, and no edges face into the flow. Can't help that with the couplings. Have never had a plug as a result.

    Dennis, most of the spiral duct I have seen is galvanized steel. It seems like aluminum would be more expensive? It is used mostly for HVAC, so an HVAC installer should be able to get all the fittings you need.

    My fault, I for some reason thought they where aluminum, but they are galvanized steel.
