I use a lot of automotive paint and it works for me pretty good in the summer. I have a pretty powerful booth in my garage and use a respirator and all the proper safety gear. That all changes as winter approaches. Living in Michigan, I have to move my operation inside. Up until this point I used a Artograph 1530 when painting in my basement. This works fine with the Createx water based paint I use in the winter. It doesn't quite stand up to the House of Kolor and PPG paints I use on motorcycles and slot cars in the summer. I had an squirrel cage furnace fan that I picked up at a garage sale a few years back. I used it mainly for getting air moving around the garage in the summer months when I am working out there.
I cobbled together a home built booth so I can use the HOK and PPG paints with my air brushes. I used a 27 Gallon storage bin with a 23"wX16"T opening. Used 1/2" plywood attached 6" flanges and 6" PVC 90 degree elbows. Tied it all together with dryer vent ducting. It has worked great, it moves a s**t ton of air. Although I don't know the cfm on this unit, It will evacuate a pretty nasty egg fart from across the room.
I use a frame made out of 1/2" pvc tubing and a couple of tarps to isolate everything from the rest of the house.
As a cautionary measure, I will not use any automotive clear in this setup. It is simply far too toxic to take the chance. And if any one else builds something in the same vein, I advise that you do the same. The hardener in automotive clear contains cyanide and you really don't want to mess with that compound in an enclosed environment. I store all my auto paint in an explosion proof box as well.
Thanks for sharing your paint booth set up. I bet that fan would suck chrome off of a trailer hitch I built a booth over the Summer that I'll share. I put mine on casters so I could roll it out to the drive way. I used an old stove exhaust fan for the lid. It works ok and I like the light but I know it doesn't compare to your fan. I also have a small exhaust fan set up at the bottom of the booth which moves quite a bit of air for it's size. My thought was to have an opening that would allow me to reach underneath (plexi-glass) to work and spray on the upper end in hopes that dust particles entering the booth get sucked out from the lower fan. The upper fan pulls out the fumes and exits out of my high dollar duct work. It works pretty good for what I'm using it for.
These are some great examples of what can be done to build your own paint booth. I have posted these pics of my "hillbilly paint booth" in another area, but thought I would post again here to show another example of how simple it can be. I am currently working on another much improved version that I am building out of foam board, foil tape, and duct sealer. It will be bigger, have better lighting, and will look better than a box on a drawer unit...lol. I built my original so that I could do all my painting inside my hobby room where temperature and humidity are controlled. The Grainger box still works very well....I'm almost going to be sad when I have to throw it away. I have found that most of the units on the market now do not have a strong enough fan for what I need. This fan came from my work and is one that is used in a large UPS system. It has plenty of draw and I use a small filter over the duct opening in the box.
I mounted it in a piece of foam board that is cut to fit in the window. I used foil tape and duct sealer which makes it very rigid. Added a pigtail so I can just plug it straight into the wall.
I taped the box to the top of my portable drawer unit so that I can roll it in the corner when not in use. Cut a hole in the box for the duct to fit in. The duct is a dryer vent kit from Lowes. When I want to us it I put the fan in the window and close the window on top of it, put the duct in the hole in the box, plug it in, and I'm ready to go. No fumes in the house at all. I use a lot of lacquer, so I would know if there was a problem. My wife would let me know. Thanks for the postings guys.
