Thread: New Dust Extractor

Don't expect too much.

Eliminating dust problems in a workshop is like trying to eliminate road accidents. Woodies that claim to have done this either don't do enough work in their sheds and have forgotten that there's always some (sometimes LOTS of) invisible dust around even if its not wood dust.

In the first post in this thread you showed a picture of the Jet dusty. I did a lot of research two years ago, reading a lot of BobL's posts here and there's another dust extraction guru in the States.
What swayed me in the end was a simple video review on youtube - this woodworker said he had a tablesaw that no dust extractor had ever cleaned out - until he got the Jet.

Ok, so far, so good.

I got the Jet for myself, in the old workshop it was running on wheels, and had a paper cartridge on top. Very very good results in my opinion.

But I've taken it further. I am now in my new shop, 9' stud, high gable, I have put the dusty into an annex and it vents to the outside, I've put
in overhead 6" wastewater pvc pipes at 10' height with various branches to radial arm saw, bandsaw, planer and jointer, and the Jet drives this setup
just fine. Best results for the latter machines is with one 4' blast gate to the machine wide open plus another half open give the best airflow.
The RAS goes directly into a 6' pipe. It works surprisingly well. I've made a large hood for that out of 4mm mdf.

I'm extremely sensitive to dust, tend to sneeze my head off at the slightest provocation, and I have no problems working without a respirator in my shop.
(I've also bought a Bosch shopvac that clears things like random orbital sander, railsaw and biscuit jointer).

I've put a sonoff relay in parallel to the magnet switch on the dusty so I don't have to go outside to turn it on and off - I can use my phone.
Going to replace that with a radio controlled sonoff though - going through a server in China is a pain when I find they've logged me out.

In my experience, Jet is at, or near, the top end of Taiwan made machinery and beats most of the China made gear by a good margin. I.M.O. and YMMV disclaimers apply.

In general I agree their gear is a step above the generics, but as far as DCs go, during my testing of DCs back in 2011-12 I found they were no different to the generics. Same filter efficiencies (largely determined by the wood dust itself anyway) same leak problems, and similar flow rates. I haven't tested the latest ones with internal wok but the main reason for this is to reduce filter cleaning- well worth having of course.

P.W.H. , Do you think I should use the FOX F50-842 .

I'v no idea what that one's like. I bought my shopvac about 3 years ago, and it was a predecessor model to this one:

https://shop.bosch-professional.com/...5-l-sfc--33010

What made me go for it was that I read some test results and the particle size that the Bosch let through was significantly smaller
than the Milwaukee and Festool which were in my opinion the closest contenders. Don't quote me after all this time, but I think
the stats I found was 2micron for the Bosch and 20 micron for the others ... pretty sure it was a factor of 10.

Looks like the new model has speed control and automatic filter cleaning. My old one (the GAS 50, bigger tank) has semi-auto filter cleaning
only (I have to throw a switch) and no speed control; it has 2 filter cartridges. I find that if I do a lot of sanding I have to pull the hepa filters
out after 2-3 months and clean them with compressed air, regardless.
Apart from that it's shown itself to be a grunty, reliable and very sturdy beast -- as I said before I am very dust sensitive and yet I can use my random
orbital sander with it without wearing a mask. The one complaint is that the rubber friction fit on the end of the hose sometimes comes out of
my tracksaw ... I also had to get an adapter to match it up with my makita biscuit jointer.

It was very expensive - about the same price as the Festool, NZ$1400-ish and that was years ago. But we pay extortionate prices here in NZ anyhow.

I will stick with the SIP model , they are both very similar in working operations . The SIP have a larger motor , so I will plump for that .
