On another thread I talked about how I picked up a monster squirrel cage blower and had intended to use it as a down draft table, well that idea has evolved and I am no longer going to use the blower for that.
Someone suggested that I make a overhead air filter from the blower and that sent light bulbs a flashing, well at least glowing a little.
I know this will not work for most people but I think it will for me so I want to put it out there and see if I can get steered in another direction.
My 18' x 32' shop in located in Northern California and while it does get real hot 110 and real cold 28 at times I would say that 90% of the time it is very nice and comfortable to work in my detached shop. I have no heating or AC, just some fans to blow when it really gets hot, like today. There is a 10' wide opening (one day it may have a door) and a 36" man door on another wall, so it is not air tight by any means.
To my point.
What if I mounted the monster fan outside and ducted the air from it to the center of my shop.
To me the point of a overhead air filter is to clean the air, so if I just bring in air from outside that is not full of dust I would be doing the same thing, If not better.
Would not have to worry about clogged filters, can wire it up with a timer so I could let it run after I leave.
Have the fan, it cost me $10.00 or so. The expense would be in the 18' or feet of duct work. Have a great sheetmetal shop in our little town so they could fab it pretty easy.
Please let me know you thoughts.
