Thread: Dust cyclone location

What size opening does the cyclone have?

What size opening does the dust collector have?

What size opening does the tool or machine have?

Cyclones work very well as long as they're matched up to the right size hose, etc.

It's a ub 3100eck which I've had since 2008

Outlet into dust bin is 300mm
Pleated filter is approx 350mm
The ports on table saw, bandsaw are 100mm, I have an old planet thicknesser with no dust collection so plan to make something up for that which can be 150mm also a few smaller ports....kapex, bobbin sander for example

I have 2 options for DC location, option 1 on ground level and the 2nd option on the mezzanine above.

Option 1 would have approx 1.5m longer run to the first machine. Option 2, I could essentially position the DC above the machines. Which location would be better? a shorter run with a vertical lift of approx 3.5m or the longer run on lower level? The inlet on my DC is 200mm which will be reduced to connect to 150mm duct. If i install the DC on the mezzanine i have more head room so would be able to upgrade to a better/more powerful cyclone in the future, could also vent through the wall at high level

Thanks Marty

My understanding (via Bill Pentz) is that vertical risers require approx 50% additional airspeed over horizontal runs to keep chips in suspension and not clogging in the ducting...

Air engineering testing shows we need to maintain an air speed of at least 2500 to 2700 FPM in horizontal ducting runs and at least 3800 FPM airspeed in our vertical runs.

Provided your DE has adequate capacity and you have appropriately sized ports, I wouldn't expect there would be much of a difference with the short runs you have mentioned.

The number of bends in your layout and how sharp they are is another factor to take into consideration. The loss across each 90deg turn can be equivalent to about the loss in every 4m length of 150mmm ducting. If there are fewer bends with a mezzanine installation it could still be more efficient, even with the vertical runs.
