[Usittne] Dust Collection question

[Keith Cornelius]

Hi--

Depends on the scope of the system you envision.  Dust collection "done 
right"--i.e. a turnkey system with central collector and designed 
ductwork--is expensive and typically requires that machines have only 
one fixed location, which can be a problem in shops where machines are 
moved around as projects require.  I've only been around the 
installation of one such system; it cost $30K in 1982.

We currently have a mix of Delta, Jet and Dayton portables; most are 10 
years old and have never given a problem.  They work okay at collecting 
the dangerous fine dust, but  are not as effective with the larger 
particles as a central system would be.  The best thing we've done to 
improve their effectiveness is to wire them through relays so they come 
on  automatically when the machine is started.

We have a FumeMaster  exhauster in our metal shop.  It's worked fine for 
12years, although the flexible hose is  tedious to drag around when 
welding large units.  An array of articulated overhead arms, each 
attached to its own exhauster, is reported to be the best approach to this.

 I've heard many good things about Oneida Air Systems dust collection 
systems, but have no first-hand experience.

You might check with officer(s) of the  National's Health and Safety 
Comission.  The did several sessions on dust collection at a conference 
a few years ago.

Good luck--I'd be interested to hear of any good sources of info you 
discover.

We currently have 2  portable dust collectors (2HP each)  one attachted to the radial arm saw  and one on the table saw, but are looking into a more comprehensive system including air filtration and possibly fume collection for welding purposes.  Has anyone recently installed such a  system or have any recommendations for  vendors or equipment that we should look into?
