I have a 90mm dust extraction system installed in my work area.
I found that I was constantly either unblocking the extractor grid or the associated pipes when I was using it.
There is a circular and quadrant arm device in the base of the extractor to prevent solid objects getting into the rotating vanes and damaging them. I was reluctant to remove it to prevent blocking occurring and then run the risk of impeller damage so it stayed.
So I researched putting in a separator between my dust extractor and individual machines.
All were very complex or expensive, so I had the materials available so decided to make my own to see if it worked.
It consists of the following:
2 x Plastic drums inverted and pressed together at the tops
A short length of 90mm PVC pipe, one in the top and one in the side, (see the grey sections)
Some silicone sealer to retain them and provide air tightness, then attached to the existing system.
The Total cost of the project (for the separator only) was about the cost of 1 x tube of Silicone. (I had the other items available as garden/guttering remains.
Does it work? yes it does. From my estimate 95% of solid matter stays in the buckets.
Now all I have to do is take the buckets off go to the compost separate and empty them
To separate the two buckets all you need to do is full the two handles apart.
Cheap as and fully functional
Why did I use 90mm in stead of 100mm, well I guess the answer is I didn’t know any better at the time, and I had off cuts left over from my water trap harvesting system seen to the left with the garden hose at the bottom.
The horizontal pipe you see was made to go across my yard ( overhead) and be supported at the end by the fence. It was a classic design fail as I was constantly banging my head on it so its now redundant.
If you are interested in doing something similar and want some measurements/ other details or more photos let be know and I can provide more, as I dont want to be seen as cluttering blogs up with no interest info/junk
