I currently do allot of my dirty work in the basement of the house and in the process or cutting(angle grinder) and profiling(36 Grit Cubitron II on a 2 HP 2 x 72) I get a lot of nasty fumes and just particles in

the air and it just not a good thing and I doubt the particle go away very fast. I wear a mask(most of the time) but I don't really want to solely trust it that much, And I don't want fumes going

throughout the house and I don't want others that are walking through to have to breath the junk...and besides I'm right there ALL the time. And what do you know it's WINTER so opening the windows(there's

some windows in the basement) isn't really an option.

I want to for while I'm working but I'd also like to run it after I'm done for a while to finish "Cleaning" the air.

So is there a way I can pump good air in and pump bad air out? What should I be doing?

Thanks Guys!
 
Waiting on this one myself.Do as much as possible with a metal band saw for starters.Vent outside?
 
I have my grinder in a 3-wall booth. At the ceiling of the booth, I have a Tjernlund M-6 exhaust fan ($90 on amazon) that pulls 460 CFMs (nominal). This is connected to some flex duct and terminates outside via a standard dryer vent (I step down from Ø6" to Ø4").

It is ideal to provide an air inlet, especially if you have a furnace that pulls combustion air from the basement.
 
I deal with as much dust as anyone on here, so I'll tell you what I use. On the grinder, I fasten a shop-vac a few inches below the platen. The $99 Rigid WD1450 is about the best out there, with plenty of suction and considerably quieter than anything else.

If you've got lots of dust, like I do, a 5 gallon bucket and a dust deputy are invaluable. I've never heard a single bad word about the dust deputy. A dust deputy will also serve as a good spark catcher for hot grinding.

For overall air cleaning, I have a 20" box fan with 3 non-pleated furnace filters taped to it. This does a great job with both dust and welding smoke. Again, for the money, you can't beat the function.
 
i took the middle road. i didn't want to invest in a whole pro dust system, but i didn't want to use a shop vac. i bought the rikon 63-100 12 gallon dust extractor. it is completely made of metal, which appealed to me. different dust collectors filter down to different particle sizes, this one is 5 microns. i got the dust deputy cyclone (with water in it) to go in front of it to catch the sparks. i also used metal accordion dryer exhaust hose/tube for the long run, its economical.
 
Keep in mind working in the basement that air enters and leaves your filter/dust system equally. If you are going to vent your system outside or to another part of the basement/house, you need to have an air intake to compensate. The biggest issue is if you're venting outside and don't have a fresh air intake. You will pull exhaust gasses from your furnace and hot water heaters (given that they're gas) into your house.

Discovered this in my garage shop. I heat with wood and was drawing the draft back filling the shop with smoke.

Daniel you've been building some really nice stuff down there in that hole!

If you want to do this long term, please don't kid yourself into thinking that the paper masks or furnace filters taped to box fans will catch the small particle sizes or chem vapors that will do you the most harm over time.

Look into this from an industrial safety point of view and learn up on appropriate PPE for the conditions you are creating in your shop. Most vendors have people there ready and willing to help. I have a well-fitted 3M 6800 full face mask and I would still rather grind outside and upwind.

Also take a look at this thread for inspiration: http://www.bladeforums.com/forums/s...-made-a-dust-evacuation-system-for-my-grinder

Take care.
