Thread: Dust Extraction - Carbatec FM-230 or Hafco DC-25

I'd recommend that you save up until you can afford a 2hp dusty

I have a 2hp Carbatec (CT2042, 1500cfm) attached to two machines via blast gates, so I'm only ever using one at a time. Even 2hp is a bit marginal IMHO, especially for the tablesaw.

I think several posters have found that a 1hp dusty doesn't really have the necessary cfm.

Didn't read your post right through - a dusty with reducers isn't really what you need for sanders, routers, etc., especially not a 1hp one.

For those a shop vac will work better, and you should be able to pick up one of those for the sort of money you are talking about. There is an Aldi shop vac (and several clones available elsewhere) that give good performance.

I didn't think there was any difference between teh Hafco/Carbatec/Sherwood 1hp dust extractors. Could be wrong but they look to me to me essentially the same machines. Keep your hose run down to a couple of metres or so for best results.

However, as Mr B said, for smaller aperture dust outlets, a shop vac would be a better bet. Apart from the 4" machines design spec, a heavy 4" hose sitting on a big adapter attached to a small dust outlet could be unwieldy to use and you may need to get a length of 2 1/4" hose to connect to the outlet. If cost is an issue, you will get by with an Ozito shop vac with 2 1/4" hose. Its a real screamer but at around $79 you get the vac , 2 1/4" hose, tools and fittings. A length of hose plus an adaptor could set you back about half the cost of the Ozito anyway, which can also be used to clean your workshop etc.

Save the foldy for a 2hp unit.

Also consider that the plumbing you install in the shed will cost more than the dusty itself - by possibly twofold at least depending on how many machines you it set up to. Plumbing is really a cost of how long is a piece of string.

Thanks for the info there guys. I live in a rental so my install is not going to be permanent. I have router table, band saw and TS against 1 wall and just slide the TS out when in use to the center of my DLUG. I will usually just drag the dust extractor out with me when in use.

TP1, are you talking about this model?

I also seen this model, but depending on price it could be just better to get real dust extraction like the models i was originally looking at

I have got the WVC951 (the smaller of the Ozitos) and it is very noisy, but works OK at sucking up the dust from my SCMS. I was interested in the larger one (about $200) but some of the experts on the forum didn't think it pulled enough air.

As a novice to dust extraction I am not sure that a vacuum cleaner style will be the best thing for a table saw. I bought a 1 hp from Sherwood for the table saw and it works well. It is noticeable that the air travels into the hose very slowly compared to a vac. I think that extracting from a saw bench needs high volume low speed air.

guerd87 - the various machines you are talking about have completely different requirements as far as dust extraction goes.

The big (proper) dust extractors like 1hp or 2hp Carbatec shift a high volume of air at relatively low velocity. This is what you need for tablesaw, bandsaw, or jointer.

The shop vacs with smaller hoses shift a relatively lower volume of air but at higher velocity. These are better for routers, sanders, SCMS, etc.

As a general rule (there are exceptions), if the equipment has a 4" dust port on it then a large 1hp/2hp dusty is needed. If it has a 2" or smaller port on it, then you're better off with a shop vac. The Ozito units are good for the money, but just make sure you have good earmuffs.....

Yes that is the one i was referring too. I still have one but use my Festool Vac instead. Bloody thing is still going and I gave it to my son as a garage vac. I would forget the $200 Ozito. A 1 HP unit with industrial type induction motor will outperform, outlast and be much quieter than the brushed Ozito motor. It does have a great range of fittings though.

I have both 2hp and 1 hp units, both with pleated filters. I don't have ducting and connect one machine at a time as and when needed. The 2HP does have more suction, but if you keep the hose run down to a couple of metres or so the 1 HP is fine.. The 2 HP also has a bigger collection bag and for the few extra bucks they are excellent value.

However, the 1 HP should be able to cope with most machines - it does so for me with my machines when I use it. (table saw, jointer/thicknesser and spindle moulder). Table saws can be an exception, however, depending on how they are designed to handle saw dust. Saws that just let the dust drop into the cabinet without any form of internal plumbing, need big power to keep them clean. However, if your saw does have internal dust handling connected to the exit chute, then a 1 HP unit should be fine as well.
