This was my HVLP set up when I first got an Oneida super dust deputy.
I rigged it up to my extractor like this as I figured it would be for the quickest & that it would be handy to keep it mobile on the existing wheeled base.
In the nearly 3 years since I did this Iāve not move it once
so clearly mobility wasnāt a necessity, also as expected I experienced quite a reduction in suction not only because of adding the cyclone (which I was expecting) but also the extra pipe & bends I used to keep it fitted to the original base.
My intention with re-jigging things was to reduce the pipework & by doing so increase the suction from its current 57% efficiency when measured against the impeller on its own.
First off I wanted to get as long & straight a piece of 5ā spiral duct as I could to the cyclone as this is beneficial for the cyclone to work effectively, although I had to incorporate a 45 degree bend on the inlet that is followed by a 2.8m piece of ducting that runs to roughly the centre point of the long workshop wall. From there the duct drops to the floor & a piece of flexible pipe is attached to it long enough to reach all of my machines, in doing this Iāve halved the amount of 5ā flexible ducting I had on the system.
A piece of 3/4ā ply was fixed to the wall & floor then braced at the top onto which the impeller unit was bolted.
I built a simple unit for the fine filter to sit on the added bonus being it gave me some much needed storage space for a couple of systainers.
The streamlining of the system has taken it up to 72% efficiency a gain of 15% which I really pleased with as a fine filter & cyclone are always going to take a toll.
But the real proof as they say is in the pudding & on Thursday it got it first real workout & performed admirably
