As my tool numbers increase, so do my DC requirements.
I’ve got a Delta 760 set up in a separate room (les noise) from my shop. I’m running my cabinet saw, an 8” jointer and a 15” planner off of it on four inch black plastic sewer pipe. Both the jointer and planner are on a 15foot run and are working fine. The table saw on its own run from the DC Y is about 25 feet, also working fine. Now I need to add DC for two band saws and a Performax 16-32 sander. I could get all the machines on a Y from the TS run that would add 30 feet. I have automatic blast gates on all the current hook ups and will do the same for the rest. I only use one tool at a time. I’ve been thinking I would add a second HF 2 HP DC for the additional tools, thinking the 760 won’t handle the extra length. But it sure would be easier and less expensive to add onto the existing DC. I don’t want to go through all the trouble of adding the additional tools to the 760 only to find it inadequate. All the engineering data on DC is bewildering to me. I know some among you have the technical knowledge to answer my question. Can I add the additional 30 feet and tools to the current system? Or do I need to add a second DC? Sometimes I think I should buy a used higher HP (3HP?) system and sell my 760. I’m trying to keep the cost around $300 including the pipe. I already have the blast gates. I will appreciate your advice.

You’re looking at fine dust with those machines, no
chips really. High airflow helps with getting fine dust.

With band saws not a lot of dust gets airborne… it
falls into the saw cabinet.

The subject made me laugh.. sorry

No DC knowledge here, a broom and customs is my current method :(

Length always matters when you are working with your wood.

I’d say if your present setups is getting your planer
chips, it’s probably adequate to get the drum sander

You’ll lose a lot of suction in bends… not a whole lot
in straight runs of duct.

If possible, you might consider relocating your DC to a more central location, which might reduce the length of all or at least the longest runs. However, that would probably require some rearrangement of your ductwork.

That said, since you are only using one tool at a time, I would think a 30 ft. run would work, especially if you minimized the number of bends and the length of flex hose, both of which seriously reduce air flow.

Thanks you all. If I add the new machines onto the existing DC, I’ll be adding about 30 feet of pipe with one Y, and seven 45’s. Would you go through the trouble to hook it all up? Or would you want more DC?

If your looking to spend $300, Get the HF for $150 with coupon. If you put it outside or in a mostly unused room, you wont need to upgrade the filter. Then you have $150 for pipe.

Btw, what automatic blast gates are you using?

My wife says that girth is much more critical.

I’m not looking to spend $300. If I need to I can spend $300 on this. Can I get away with adding the additional pipe?
