Thread: Dust Extractor - Place Inside vs Outside

Either will be ok. If you enclose it inside the shop the enclosure will need to be air tight or any fine dust escaping the DC will enter the shop. Outside is easier from that point of view.

To vent the enclosure you will need MANY small holes so single large port is better and it ideal should be ~4x the cross sectional area of you main trunk line.

It would be close to neighbours fence, few meters so I can imagine the sound would suck for them...

If you look up noise reception in the Dust forum you will see ways of how to reduce the noise levels of any enclosure. It's not that hard to do - basically in involves adding a muffled S bend to the exist port of the enclosure.

Your Council may have a rule about how close to the fence it can be. Also how many decibells it can emit at different hours of the day.

Right, will ring the council and see if any issues, I figured it would just be general noise restrictions.

Internal: Need to build an airtight enclosure with a door for access, but it seals. Then a big hole in the wall for exhaust venting
External: Just a weather cover, inlet hole through the wall with ducting running along ceiling/walls, noise is concentrated outside

Do you know of any threads that show an exact setup? I found lot's of discussions, but not that many really clear setup guides/pics?

I'd be careful about dealing with the council.
I always reckon in these small cases it's better to ask for forgiveness rather than permission as this will open up a can of worms.
It's likely they will require you submit a plan (maybe even and engineers certified plan) and not to put anything permanent up including any sort of cover.
Then they may want to inspect it and it goes on and on from there.

The main practical thing in our area was is if any sewage ran lines under than part of a block, whatever was built could be removed quickly.

Setups range from a small off the shelf garden shed though to a dedicated Acoustic Enclosure
Here's how I did mine - I have a very picky neighbour and was determined to get the sound down to less than his pool pump on the boundary.
BobL's shed fit.

BTW, it depends what level of noise reduction you are after as just "weather cover" and "low noise" do not sit well with each other. To be an effective noise blockerthe enclosure will have to be quite well sealed otherwise the noise will leak out through the holes

Thanks, yes I was thinking of a very general call 'friend might be doing...'

That's a lot of info to digest, thanks!
Building it inside sounds like much less of a hassle. Just building an enclosure to make sure it keeps as much of the dust in as possible.
I figure anytime it is on, I would be using hearing protection anyway. It would just take up a decent chunk of space.

Will keep looking at plans, but thinking outside might be a bit much for me to get right.

That can be a real problem. Unless you have a big shed or there is no other choice I reckon internal shed real estate is too valuable to allocate to DC.

That was the original thought, but trying to hook something up good enough outside sounds like more of a headache now.

My shop is 8m long x 6m wide, currently doing a layout plan to see how it could all potentially fit together. Not sure I'd lose a lot of functional space putting it in the back corner.

Still not sure of the layout. Would it be possible to go "on the roof" of the internal shed?

This would also normally be my view, too, Bob, but our Council's patience has been exhausted mainly with respect to placement of heat pumps and pool pumps.

The problem has largely been created by the cowboy installers contracting for a major discount retailer.

I can understand anything to do with plumbing as that normally involves pipe work and thus requires a plumber. A DC should be literally, unplug, and move it away - DC ducting is hardly specialised. On my HD enclosure the doors are on lift off hinges, all the roof and wall panels are just bolted together so if needed I could I could move it very quickly. Of course it still doesn't pass the pedantic council test - fortunately the rear neighbour has grown a bunch of large palms along the boundary (yeah they are a right PITA dropping all manner of crap over my shed but they also hide most of the rear of the shed including the DC and compressor enclosures so that google earth or similar snooping can't see anything except these palms. If the sewer line has to come up those palms are going to make my enclosure look like LEGO

No it is a slanted roof without a real ceiling space, so don't see it on the roof.
Looking at the layout, I think I can make a single bag system and cyclone fit - Will just look for the right product combo.
Think putting it outside would be a secondary plan if inside doesn't work out, just sounds a bit more complicated to get right and make it worth it.

Rather than contacting council just check on their website to see the rules/ restrictions for location of pool pumps and A/C units, if you comply with them I don’t see an issue down the track unless they view your setup as a business
