Dust extractors: Which out of these three should I go for?
Good morning fellow woodworkers,
I am in the market for a new dust extractor for my workshop.
I've got 8 wood working machines, each piped into my central dust extractor system.
I only use one machine at a time. The biggest chip producing machine is my 3HP thicknesser, which is positioned nearest to the dust extractor unit.
My workshop has 100mm PVC tubing and no hard corners (2x 45 degree elbows instead of 1x 90 degree elbow).
Originally I was going to buy a Laguna system from Carbatec but now it seems that Carbatec no longer sells Laguna dust extractors. Also, the price is out of my range.
Anyway,
I made a shortlist of three system that will, most likely, suit my needs:
Carbatec CDC-850P @ $1,599 (Carbatec CDC-850P 2-stage Cyclone Dust Collector | Carbatec)
Sherwood SCDC-1900-H @ $1,599 (https://www.timbecon.com.au/sherwood...dust-extractor)
Machineryhouse W318 @ $2,035 (https://www.machineryhouse.com.au/W318)
So, the key question: Which one is the best out of three and offers the best value for money?
Ideally, I would like to have a remote switch with this machine: What would you recommend?
I hope somebody can steer me in the right direction.
None of these machines is currently in stock but I'm happy to wait.
Thanks for your honest and neutral opinion.
Cheers,
Luke

Which one has the biggest impeller?

That's what I don't know.
The Timbecon 2HP or 3HP look identical. The specs are sketchy to say the least.
I wish there was a universal standard which would make it easy to compare units to one another.
Alas, as a customer you need to put all your trust in the seller...
Luckily we can rely on feedback from fellow woodworkers on the forum )

Forget horse power, a 14" impeller will flow the same if driven by a 3hp motor or a 5hp motor.

The one from Machinery Warehouse would be my choice, simply as it can accept 6" ducting.
I was using a 1, then 2, then 3HP DE over the years. Each step up in suction was phenomenal. This corresponded to upgrading to 100mm (4") then to 150mm (6") ducting.
The 6" ducting is absolutely incredible. Worth every cent. The volume increase was incredible.
@BobL made me some venturi-like ends too. Those things created black holes of DEATH for dust! On the lathe they were fun to watch....
My machines were simply attached with the one piece of 3-metre pipe I dragged around.

might be more prudent to move this thread to the dust extraction section

Given you're using 100mm ducting, "it" rather than most DCs will as a limiting step to air flow and dust extraction, so it won't make any difference what DC you get.
100mm is limited to about 425 CFM which is nominally about 40% of what is required for dustier machines.
To get to a point where the air flow covers most machinery (1000CFM) you will need to use 150mm ducting AND at lest a 3HP machine AND doctor every machine so it has 6" dust ports AND has plenty of pathways for fresh air to enter each machine. If no air can get "in" then no dust can get out..
Alternatively if you stay with 100mm you should look into forced ventilation to continually vent fine dust. You should target 20 room air changes per hour.
How big is your workshop?

Now we are moving from the original question and getting to replacing the entire system and buying a machine that needs modifying as soon as it is bought all beyond the budget limit set by the OP. If we are going there forget buying a machine that has to be modified and buy one that simply works. Both are out of budget anyway.

My workshop is about 29m long, 9m wide and 6.3m high (The walls are 4m high).
I am planning to upgrade to 150mm pipe. I will start with the centre pipe to be 150mm and then reduce it to 100mm as close as possible to the machine. All my woodworking machines have either a 100mm or a 50mm (Router) connection.
Thanks BobL for shedding a light on the numbers. I wasn't aware that 100mm PVC pipe only allows 425 CFM.
So, from what I can read I think I might buy the HAFCO system then.

Thanks Chris.
Obviously it would be great if you can buy something off-the-shelf and start using it without modifications.
However, I've got a bit of leeway in the finance department but want to keep it reasonable. (That's why I stay clear from the Laguna DE's).

Pretty hard to force ventilate a shed that big.

A couple of these should work.

Yes, I'm quite happy with that. I've got it split in three sections: Woodwork, metalwork and my brewery.
I've got two big roller doors as well and a veranda along the length of the shed.
If it's not too windy I open up the roller doors and the windows on the opposite side. That provides plenty of cross ventilation.
It's not that I'm doing woodwork on a daily base. I just do maybe two or three projects per year. That's why I'm looking for something "economically priced".
But besides all the practical details I still want to find out which out of the three DE's would be the best one.
Once I've got my DE I can then start looking to upgrade the PVC piping.
