Thanks for the feedback everyone. I’m in Virginia and even on very cold days do not have to heat my basement shop. So heat loss is not an issue I worry about. In summer it stays fairly cool as well even without A/C.

I am a hobbyist so my big machines don’t get much use.

I’m 60 and should have done something about dust collection 30 years ago! I usually open the shop door and have a big fan on wheels that sucks the dust outside. It’s’ not been ideal for the lungs. So, better late than never for a real system.

Is it OK to use a 4 inch main duct as well as 4 inch connectors to my machines? The total length of the main run would be about 20 feet and the connectors to my machines coming off the main would be fairly short. That would make my system even simpler. All’s I would need is some PVC (I read that sewer pipe PVC is as good at half the price), some blast gates, and the HF impeller venting outside. Not sure if i’m missing anything here. I gather that the impellor can withstand planer sized chips flying through it?

We’ll see how it works. I can always add a separator, etc. down the pike.
