Extraction setup for AW106PT2 and band saw

YorkshireMartin · 31 Aug 2015

Hi all,

First post, I hope nobody minds that it is a question.

Workshop extraction has been covered many times on the forum as I've seen whilst browsing. I've just not been able to piece together a strategy.

I have a garage workshop with a ceiling height of 6ft 2. I have an Axminster AW106PT2 on the way and plan to add a band saw also. I don't want a fine layer of dust all over the garage, so I'd like to rig up a method of extraction that has the volume for chips, but filters all the way down to 0.5 microns, ruling our the optional (expensive!) filters for the Axminster hobby series extractors.

With limited space, the closest thing I could come up with was the Camvac CGV286-3-WALL. 150 Litres, 2000W and fine dust collection sounds great. As it's wall mounted that will help in the space I have. I cannot position an extractor outside at the moment.

I spoke to Record Power and they advised me that the Camvac is LPHV. That goes against what I'd been reading, which was that all Camvacs are HPLV in the manner of a workshop vac such as the Festool CT26 and used for fine dust collection such as that generated by sanding.

I'm not sure what to do. Would the Camvac suit this application or am I barking up the wrong tree? Would adding/making a cyclone and combining it with the Camvac work? I looked at commercial cyclones but they seem very expensive for what they are, although making one seems to be an option.

Any advice would be most welcome.

Thank you.

Ca vac are HPLV they are vacuums rather than a great big blower in reverse. I used such a system for years it will work but not brilliantly. It will block up and you will have some fine dust. As long as you keep the runs as short and straight as possible it will give adequate dust and chip control.

i have a camvac hooked up to the bandsaw. I also plan to hook it up to py PT, but I haven't used that in a while, since getting a lathe.

You will need the cam vac with a fair bit of suck- mine is the twin motor 4" model. I have introduced a simple drop box, nd there is no dust in the cam vac, so it must work pretty well.

Thank you for the replies gents.

marcros, what is a drop box? It's not a term I'm familiar with.

it is a simple blue food drum, with an in pipe and an out pipe. It works as a simplified cyclone, where the air is disturbed, slows down and the dust falls out. It is probably not as effective as a cyclone, but like I say, my cam vac is empty.

mine is bigger, but this shows you the concept- I used soil pipe fittings on mine, being 4". http://www.instructables.com/id/Drywall ... Seperator/

You are only using the cam vac for suck, so I have a very small capacity on the vacuum- the drop box is the thing that is emptied, hence why I have a decent sized drum on it.
