I originally bought the "AXMINSTER CRAFT AC118CI CYCLONE INTERCEPTOR", here:
https://www.axminstertools.com/axminster-craft-ac118ci-cyclone-interceptor-105844
And later upgraded it to use a 120litre blue barrel. I reinforced the barrel lid and installed a dust commander pressure relief valve per the installation instructions. The barrel was a new one (I didn't want to have to deal with any nasty residue) for about £40. This system worked brilliantly with a 1KW CamVac, but I suspect it would work equally as well with a chip extractor (Axi recommend 1.5HP and above). You can completely block the hose safely without collapsing the barrel, the relief valve does it's job as intended.
I'm asking £125 for the lot, it's all in excellent condition. I think that's about half new price for all the bits and a chunk less than just the head by itself. Collection only from (near) Ross-on-Wye, cash on collection please.
