DC setp up help please

[Vlad]

Recently I moved to a large shop with a house attached and I am about to set up my DC (Delta 1.5hp unit) to my stationary tools. I was planning on using 4" pipe but I have some 6" pipe available. Would I have any benefit in using a 6" pipe from the unit and reduce to 4" pipe close to the equipment? How about 4" to 6" back to 4" again? Does Delta carry a 6" attachment to replace the 2-4" attachments (on the blower)?

Thank you.

Hi Vlad -- I use 6" pipe off the cyclone for the main run and use 4" drops to the machines. I have a 1hp King blower on a Wood Cyclone and it works fine. I wouldn't do the 4" to 6" back to 4" thing as you may be creating a mini drop box kind of a deal. The foregoing observations are based on personal experience. I am no expert. FWIW

DC's allow you to remove the two 4" units and there is an inlet pipe underneath that will be either 5" or 6 inches. I ran 5" from mine (which is the size of my inlet on the blower) to the preseparator and then ran 4" from there. If I did it again I would run larger pipe right from the blower inlet and carry it on as long as possible. The idea is to have as much air flowing in the pipes as possible.

You need to make sure that the larger pipe is the correct guage. 30 gauge is too small for 6" pipe and larger DC's. I used 26 gauge on both my 5" and 4" and this seems fine.

I also finally got fed up with the grid at the inlet plugging up with clumps of shaving from the jointer or planer and removed it. I have this bad habit of just doing a quick run on the jointer and not turning on the DC. Unfortunately this create a clump which gets sucked up whole and then gets caught in the grid at the inlet at the blower. The other problem I had with grid was blowing sandpaper rolls into pieces on the drum sander which would then get sucked up and plug the grid. The DC still works but degrades in performance and it always would take me a while to catch on to this.

Vlad:Do you get this magazine at all? I have done a series of articles for them that cover your concerns. Basically the main header for your shop should be no smaller than the main fan inlet. If your unit has a plastic "Y" on the front of it take it off and deposit it in your shops trash can
as that is where it belongs.The piping should be n less than 28 guage for 1Hp 26 for 2Hp and 24 for 3Hp. (these numbers are if you are utilizing "smoke pipe"). If you have any further questions contact me at my "E" mail address.
