After a bit of experimenting I have ended up going with a high velocity low pressure bag style vacuum unit I got used of eBay nice and cheap and local. I thought this was the best solution because the foam dust is so light and the hvlp units are nice and quiet. The only thing now is trying to decide how to run the vacuum hose and in what size. The unit will be at one end of the 6meter table so can't decide if to run a solid pipe to the centre and then come down some how with something flexible or to have flexible the hole way on some sort of curtain rail type thing

You want 4" pipe minimum I would think, 6" even. I would use solid pipe as much as possible, people use the 4" soil pipes. Flexible pipe has ridges where the metal spiral is and this restricts flow.
If you use plastic pipes you need to wrap some earth wire around them to drain static away, some people have experienced explosions.Last edited by EddyCurrent; 09-12-2014 at 10:26 PM.
