Smoke Eater (Air cleaner) for the bench

[PJs]

JR, I'm with Paul on your shop setup and the chips and salsa from your other post...Really Nice! I love that far side parting post!

Nice build on the filter. It has plenty of CFM available based on the curves for the fans, but like most box fans they only have a Max .77InH20 @ 0 CFM per for a static rating. That being said and you being right about getting specs on that filter...ISO/NFPA = NA there is no way to know where you will be on the Static/CFM curve in the end, so it can only be empirically (nose/dust) tested or with some kind of flow measuring device. Curious how far out from the inlet can it pull smoke and fumes? I also applaud you for adding the carbon mesh filter downstream as it should help considerably with solder and oil fumes.

Sounds like it's working fine so far and the nice thing about your design is that if you find the pleated filter is too restrictive or not working as well as you want it, it can easily be changed to another type of the home made variety with cloth and stuffing. I've often thought of making a small snorkel system using a good sized fan like you chose...up close and personal to the work...just never got my Roundtoit out of my pocket.

Thanks JR!
