When I built my Shapeoko XL enclosure, I included a basic dust collection system. It’s a traditional two stage system, with a Dewalt shopvac providing the suction and a Rockler dust seperator separating/capturing the dust.
When I looked inside the dust separator I found (after weighing) 162.7 oz of dust. This was from plywood, hardwood and a small amount of polycarbonate.
I then took the bag out of the shop van, and emptied the bag into another container. I found that the bag contained 80.7 of very fine dust. Way more than I was hoping for, not sure if my expectations are justified but I as expecting about 1/10th of that.
The math suggests my dust collection system is only capturing 66.8% (162.7 of the 243.4 total) of the dust.
The lid of the Rockler dust separator has two 90 bends under the lid.
My enclosure was designed for these parts, I don’t have a lot of additional room.
So how can my dust separator be improved?
