Dust Collector

[yorkie]

So, I'm selling my Jet DC-1100VX-CK Dust Collector and replacing it with the Powermatic. I love the Jet but I just want to try to squeeze some more CFM's for the distance I'm travelling with it.

So, this leads me to my question. I currently use the flexhose from my DC to the lathe and I understand that can reduce the CFMs due to turbulent air flow??? Is it a good idea to replace it with 4" PVC pipe all the way from the DC to the lathe?

Thanks, guys.

I'm just going out on a limb here: yes. More bends, elbows, ridges in pipe, etc. will increase resistance across a system. By running PVC as straight as possible, you SHOULD maximize volume of flow.

I do this for a living. Each long elbow is worth 5ft of length. The flex hose has more resistance than PVC for sure. Straight and tight works best.

My jet has a 6 inch take off split from jet with 2 four inch take offs. You will get the best CFM by using the 6 inch fitting with 6 inch pipe, and the reducing it at your machine. There is some debate about making sure you piping is grounded to stop explosive dust. I can not answer that question. They sell the wire at WC. You can also use sheet metal snap lock pipe. The 6 inch metal is very cheap in comparison with PVC pipe. It is also much lighter. Seal the elbows and other joints with foil tape or mastic.
