Nordfab design with Clearvue CVMax

[Wakahisa Shinta]

Hello,

I am laying out Nordfab ducts for a CVMax cyclone (not purchase yet) using SketchUp 3D models of the ducts. I plan to go with Nordfab for future modification in case of relocation and expansion. Expensive, but probably worth the investment down the road.

8-inch main

Nearest to the cyclone, the first two branches are for a Felder KF700SP. One branch is for the saw operation; the other is for the shaper operation. 8-8-6-inch, 45-deg wye before connecting to a 6-6-4-inch, 45-deg wye then reduce to 5-inch hose connector. Each branch with its own blast gate.

Next two branches are similar, 8-8-6-inch, 45-deg to 6-5-5-inch, Y branch for bandsaw and floor sweep. The branch left of the bandsaw is for a drum sander on mobile wheels.

Next is another 8-8-6-inch, 45-deg wye to a Felder Dual 51 jointer/planner with 6-inch port and the drill press.

After that, the main trunk is reduced to 7-inch and split two directions using 8-8-8-inch, 30-deg wye. The rest of the wyes are 30-deg branch and ultimately reduce to 5-inch hose connector.

The two 90-deg turns use long-radius elbows, 8-inch diameter.


Nordfab makes a 11-deg elbow specifically for the CVMax to level out the duct run because the entry angle of the cyclone inlet is 11-deg. I haven't done any rough math, but I don't think this would work for my shop given the short distance between the cyclone and first wye branch for the saw.

I am looking for feedback regarding this design. Any change should be made given the collective experience of the forum members. My shop is a 3-car garage that is more of a 1-car garage during certain time of the year!

Thanks!

A perimeter design isn't necessarily "ideal" from a duct length point of view over to the J/P which is a major chip producer, but if conditions dictate you take that path, it should still be fine. If you want to play with the idea, cut a diagonal off a wye from the run on the cyclone wall over to the J/P to service that (and the intermediate overhead drop) and points beyond and just stop the run out to the big bandsaw at the big bandsaw.

Jim,

The perimeter design is the only option for this space. A diagonal run from the cyclone to the JP is not possible due to structural objects such as garage door tracks, opener, etc. If these were not in the way, I would have gone that route in my design. Thanks for the suggestion.

I figured there might be something that influenced that path, but had to mention things as I did just to be complete. I think you'll be fine.
