G'day to you all! My shop needs a dust extraction system. I was thinking of maybe a two outlet unit, low noise with plenty of power. I reckon it is often better to buy a system a little bigger than your needs.

What do you all use and some product links would be appreciated. I have about $500 to spend.

Cheers

I'm running a Jet 2HP 1200cfm unit in my shop.....its got the pleated filter and it does a good job. It cost me a bit more than $500 though.

The downside to the Jet machine...Jet service is not good in Adelaide (a long wait for delivery) and it sounds like it's not a whole lot better in other centres. I'd look at the Carbatec equivalent.

If youre on a tight budget and only have one or two machines to service then this might be of use to you:

I'm running a 1200 cfmDC3 from Hare and forbes $319.
If you are able to locate it outside your workshop it will be fine, if inside you might consider a pleated filter to replace the bag filter.

2Hp Carba-tec at about $360 plus freight, (the cost of living in a place as beautiful as Darwin) placed outside the workshop like Jeff. I knocked up a small lean-to to shelter it and duct with that 90mm stormwater pipe (cheap as chips, about $10 for 6m) I also make my own butterfly valves to suit the 90mm that are cheap and work well to isolate different machines (yell if you want a idea of the valves Alan).

im running a 3hp 15amp beast from hare and forbes. it literally will suck your clothes off but removes most dust before it enters your nose. 2300 cfm. it is $519.00. good price but electrical outlets are important due to 15 amp power feed and a draw on 10.7 amps unloaded and 12 or so under load. couldnt be happier with it.

Thanks everyone for the advice.

Jim: Is this the unit?

Alan, i have the same model from Carbatech FM-300, does the job well, got it connected to drum sander and band saw, gets most dust away, very little airborne particles to speak of, very worthwhile purchase i thought. Cheers,, Rod.

Hey, I have the CT 2HP tradesman model.
http://www.carbatec.com.au/carba-tec-2h ... ctor_c1430
It has a better fan housing and is more efficient than the standard 2HP model and you tell the difference as I used to have the standard model.
It sits under the house and I have pulled off the double 4 inch inlet and put 6inch ducting from it through the wall into the workshop and then run it around the wall just under bench height. I wanted to minimise duct length as much as i could and this placement works well. The metal ducting cost about $500 alone but I will never have to replace it. Bill Pentz recommends the larger duct size as it can move heaps more air which means more dust.

I think we tend to skimp on dust extraction when dust can be as dangerous or more so than many of our machines. It just kills us far more slowly. I am glad I did it properly. The larger duct size means it sucks up almost everything. I have almost everything connected now including a good downdraft table. I have 6 inch blast gates at each machine and a switch in a central location so it easy to turn on.
Its also worth investing in some mods to machines to help with dust collection. I did this on my table saw.
Sealed the under table to cabinet gap and any other holes with spray foam. Enlarged the outlet from the standard 4 inch to 6 inch. Cut inlet vents in the door so the air flows over the motor to keep it cool and clean. Put a magnetic cover over the tilt slot hole. And cut another inlet opposite the outlet so the air flow helps the dust into the duct. I am also thinking that an inlet with a tube that directs air onto the spinning blade may help clear the kerfs and prevent dust flying back out of the cabinet.
Hope this helps

Yep that is the one Alan.

I think it is worth noting that it doesn't matter how big the dust collector is, machines still spit a bit of dust out. Extraction is not the end of it from a safety point of view. I use pedestal fans for cross flow ventilation and I reckon dust masks are not obsolete even when you have extraction and good ventilation.

Even my mate with his industrial set up that has 400mm or so diameter ducting that reduces to each machine still has dust all over the place and his extractor is so gutsy it sucks up and mashes (or should that be minces) possums (would be good environmentally in New Zealand).

I have a drum sander, small bandsaw and belt sander that need dust control. At the present time I have all three units mounted on a sturdy base with casters so as if its the belt sander I want to use, it is very easily located to the outside of the shop under the back patio. The plan is to take the extractor outside too and hook it up to the machine being used. I like that setup as the machines are used out in the open air. I use a dust mask too! My neighbour will appreciate the dust control as her car garage is close and often the car gets covered in dust. Smile

The washing gets hung in the garage during the winter months at my place......dust control is mandatory or else I'm made to re wash the clothes. The washing often hangs right next to the dustie but so far I havent seen a speck of dust in the clothes.

Those filters do seem to be the bee's knees Martin.

Good on you for looking after the neighbours Alan. I recently did the same by knocking up a spray filter system to stop the solids and take the smell out of the gas.
