Thread: Exterior enclosure

What is the absolute smallest enclosure I can possibly build?

What is essential is that there is enough air path clearance around the filter. Obviously the more clearance the better. On mine I only have about 50mm clearance around the sides of filters but don't forget I have 2 filters so thats the same as having 100 mm around one. On the top I have much less clearance - probably less than 25 mm which is not ideal.

and b) if all the dust is going outside of the workshop do I need the filter on the top? It would reduce height a lot if I could somehow remove it or reduce it.

Yes you definitely need a filter of some kind to let the air escape. If you leave it open sawdust will cater far and wide especially as teh collection bag fills up.

To reduce the height of mine I took it off the DC base and suspended the DC itself on a wooden frame so the collection bags slightly scrunch up and sit on the ground and this reduced the overall height requirements by about 100mm.

Thanks
Do you have a photo handy by any chance? I'm struggling to visualise the wooden frame with the DC suspended.
Only if you have it handy

Thanks again!

Sorry suspended is not really the right word - it just stands on a new wooden frame

Well mine is not a standard DC but this is what it looked like originally when I bought it.

I ditched the 4 x 100 mm intake, and the bottom part of the frame with the bag trays and the wheels - the frame comes apart at the ted lines

The I added shorter wooden legs like this and note the plastic collection bags sit slightly scrunched up on the brick paving.
The DC does not touch any part of the enclosure - at one stage I had it suspended from the walls of the enclosure but then it transmitted vibe to the enclosure walls and released more noise externally.

Recently (last week) the 3HP single phase motor was replaced with a 3P 4HP metre and a VFD so it can spin faster and pull even more air.
