Paint Booth
Posted by DaveS70 on Wednesday, January 28, 2004 10:28 PM
Anyone out there have a scratch built spray booth? I followed an example of one that I saw in Scale Auto but don't think I have a fan powerful enough for the job. I was wondering what you may have used for your fan. Right now mine is just a bathroom ceiling fan that was a cheap model probably only runs at 50 CFM for air circulation. I have looked the specs of the Testors and PAASCHE booths and it appears that they run in the 180 CFM range. I like my booth setup but need a bigger fan and can't seem to find one that speed without going to something like a kitchen fan. Anyone have any ideas on what else I could look for and where. I have shopped at Menards and Home Depot so far, which are all I really have in the way of bigger stores where I live (without traveling).

Thanks for any help
Dave

There are a couple paint booth topics posted some where around here. Use the search function and you can read up. Some very interesting ideas on this topic.

I have a article FSM did a few years ago that I used to build my booth. Email me with your name and address, and I will copy and mail it to you.

I just built a paintbooth myself after doing extensive research. You DEFINELTY do not want to use any type of bathroom or stove hood fan. The fan will suck the flammable fumes right over the motor coils...a recipe for disaster. You want to get a Dayton "Squirrel Cage" blower (pulls over 280 CFM) thru Grainger. I got my hands on a copy of Model Railroader from 1983 that had an excellent article on the paintbooth contstruction...it was made from sheetmetal but I used the specs for plywood construction. It called for the Dayton blower and also had excellent wiring diagrams for the blower, light switch and plugging in your compressor. My booth works like a charm..the blower really provides a good, powerful exhaust and is pretty quiet. I can get you more specific info if you are interested. BK

Good point about the blower selection BK651! I knew there was something bad about using a bathroom fan that I heard about but I couln't think what it was. Grainger has some great things in their catalog, don't they? Awesome stuff that you won't find at any Home Depot. Thank's for that very important tip BK! You probably saved someone's life.Dead

The fire hazzard does not apply if you are using acrylics, though. Big Smile

I definetly agree with bk651. I did the same thing he did, after much research I built my own booth and went with a dayto blower they can be pretty price but you have to know where to go. If you can get one through Grainger It is definetly the cheepest. i got mine from a place called specialty-lights.com just search for dayton blowers. They have all different sizes, parts and they come pre-wired with a 10 foot cord.

I did the same, built my spray booth out of plywood and used a Dayton blower that I got on Ebay (they come at $25 plus shipping every now and then for a slightly used unit, not a bad deal since a brand new one is around $100). It works perfectly, is not really noisy, and in fact I use the booth as my workbench when I do not paint. I even put a removable wood door so I can close it when I am finished modeling and nothing is left exposed to dust.

Build yours, it is not that hard and it will be much better and cheaper than commercial models.

The grease from cooking is flammable also so the stove hood fans are not as dangerous as people think I would believe. Now I am not advocating spraying lacquer or urethane's through them, but for enamels they may be fairly safe although a squirrel cage blower as you mentioned would be a better choice.

That is not necessarily true. What are you thinning the acrylics with?
If you thin them with isopropyl alcohol there is still a danger as it is flammable.

I was able to get a blower through Grainger, through my employer. I had our Maintenence manager stymied though. Brought me the package yesterday to my desk and could not for the life of him figure out what I was going to do with a blower and the filters, since I work in the office doing payroll. He thought it was a cool idea when I got done telling him about what it was for. Now I just need to reconfigure the back and get some bigger duct to send the fumes outside, then it will be back to modeling.

Thanks for the tips.

Is Tamiya thinner flammable? I have never read the label. It does smell like rubbing alcohol, though.
