[TheForge] positive pressure room

[Jerry Frost]

I only have a couple things to add to the thread, most 
has been covered pretty well.

If you set up a dust collector system be very careful 
what kinds of grinding dust you mix in it, some make 
pretty flamable mixtures.

If you have a swamp cooler available it'll make a 
superb filter. The water flowing over the humidifying 
mats will remove most everything from the air. You 
might have to turn up the water supply a bit to get a 
good water curtain.

The only downside to a positive pressure room is if 
there's a leak to the rest of the shop, it'll blow 
dust, fumes, etc. into the shop as or more easily as it 
will through the filters.

I've planned a "clean" room in my shop to keep the 
welding, grinding, smithin crud off my machine tools, 
etc.

For the exhaust system in the shop I laid an underfloor 
grid of 3" PVC pipe with 2" receiver tubes on a 2' 
grid. The receiver tubes will be floor anchors, tool 
post mounts, exhaust ports and whatever else fits.
