Default Dust Extraction - Where to start?

Hi, Im pretty new to woodworking in general, but I can see it being a serious hobby for me.

Currently I have no dust extraction, but now that I have had a bit of a read around this forum the dangers of dust have become apparent and Im now paranoid the microscopic dust is planning my demise!

my "shop" is a generously sized garage, its primarily used for storage, but its slowly becoming just a woodworking area.

I dont really have the money spend on some huge industrial system, so I would like to start small and build up as my interest grows.

If I got a good shop vac and an air filtration unit would this suffice for the meantime? Can anyone recommend any products to me (in the uk)?

Any input welcome.

Cheers
Neil

Is this the sort of thing?

record power DX4000:
* 106 litres/second
* 2 x 1000W Motors
* Filters to 0.5 Microns

I cant post a link to it as i'm a newbie
(its on screwfix.com if you want to search)


also, without sounding like a complete newbie, how do you attach such a large hose (102mm) to your smaller woodworking tools....

thanks again!

Neil,

I cannot speak to the best sources in the UK but can tell you that you can get started rather inexpensively. You will be safe but not as comfy as you'd like with a good respirator. Not the cheapie disposable ones but they aren't all that expensive either. I picked up a 3M 7500 series respirator, a couple of sets of HEPA rated dust filters and organic filter cartridges for ~$50US. The organic filters come in a sealed package and will "age" from being exposed to the atmosphere so keep them in a plastic bag when you aren't using finishes, solvents or glues with VOC's.

The filters will keep you from breathing the dust and even after you get set up with a DC and air filter, you'll have them for spraying or areas where the DC doesn't work well.

Others here will reply specifically to your question.

Neill,
After a respirator, I would focus on collecting dust at the source. A good way to start would be a portable dust collector with a minimum CFM rating for your most demanding tool. This unit could be moved around the shop to service tools as needed. This would save you the expense of ductwork and a high power system.

After this tool, I would purchase an ambient air filter.

As you build your tool collection with portables such as sanders, routers, etc., consider dust extraction as a critical element. Some manufacturers, such as Festool, are well-advanced in this area.

You can find a wealth of information, including CFM requirements, etc. here. There is a lot of information to digest but it's well worth your time and effort.

In the meantime, you could always evacuate the air in the shop with inexpensive fans as weather permits. Good luck!

Joe

Hi, thanks for the info - I have began wading into that in-depth article.

Currently I have the following:

Ryobi plunge router: teeny dust extraction port
Rexon Compound mitre saw: 2" dust port
Black and Decker belt sander: teeny dust port

I posted a reply earlier to this thread but its in limbo because I am a newbie

I have found a twin motor 0.5micron portable extractor, with a 6" hose - though im not sure how to connect to my current equipment.

I was looking at the Ryobi router table at some point as it has a "dust hood" which I could hopefully connect a good extrator to

Thanks again

Thinking about it, can you get the Clear vue cyclones in the UK anywhere? It might be worth the investment

Sorry for all the posts!

yeah thats the one.

I dont mind lugging it round connecting it to the appropriate tool, but to be honest it will be in the same place most of the time

Neil,

I have a DC (a Jet DC1100) that has 1 motor, about 1,500watts. That handles 1100 CFM, which is about 500 liters/sec. The unit you describe (based on motor size & air volume)sounds like it is designed to provide suction-power more like a very large vacuum than a dust collector. As a reference, the Clear Vue's run about 1400 - 1950CFM (660 - 920 l/s) . Their motors are 5hp (a bit less than 5000 watt).

With dust collection, its not so much the suction power (although you need some) as the volume of air moved & velocity. Standing in front of the ~150mm impeller discharge hose will move paper 6 meters away. A DC impeller ranges from 250 - 350 mm in diameter.
