A Passive Micro Dust Extractor

[charlese]

Always thought this helped, but today proved it. My stand alone shop building (16'X20') is on the back of my lot. Sitting here in the hot desert sun, I thought to put a vent on the roof. These are sold at Home Depot - brand is Whirligig. It has the ball bearing spinning blades on the top. I did this for heat relief in the summer, but later thought it may help in exhausting those micro dust particles - You Know - the kind that gets in your lungs and are damaging.

Today, we had a stiff wind and I thought I would see if the Whirligig did, in fact pull air our of the shop. I put a piece of corrugated cardboard over the 10" circular opening in the shop ceiling and it sucked up there like being pulled by a big vacuum.. It stayed there all day long.

If you have a shop that you can put one of these things on - It's sure enough a good micro dust extractor.

That sounds like a good idea. And I wish I had your shop. I am not allowed to have a detached building on my property because of covenants. I'm thinking that I have a good reason to move, but convincing the wife is another thing. BTW, is that grass? It looks more like some kind of gravel. Am I right?

I Love my "grass". It's gravel. Actually green gravel. It looks grey-green when dry and turns green when wet. I mow my lawn with Roundup!

Thanks for the shop envy! I like the little shop. I can muck up the insides as good as - maybe better than most!
