homemade paint booth!! BLAH!

Hahaha

so i made my own paint booth, would have worked great cept, the fans...

i used 2 120MM 90CFM computer fans, and i don't think the "Mouth" of the fans are big enough to cover the entire box. Spray-Bombs don't work very well :(

now i've 2 120MM computer fans with no use, and time to look for a bigger fan, or maybe buy a paint booth...

Try getting a 30cm extractor fan like the one used in a kitchen...might work a lot better :)

Don't mess around with computer fans. Get a real blower one of the best around are DAYTON brand. You can get them for less than a 100 dollars US, you have to buy them by mail order probably. This is the typical blower style to look for.

i've been considering using a dayton blower, but might be hard to mount.. so id unno

i'm looking into a bathroom/kitchen extractor fan for now, should be cheap!! i hope!

I made a rougn spray booth using 2 120mm computer panel fans, and it works great, so I don't see why your's shouldn't.
Admittedly it is not the ideal application for them, but they are brushless and I ducted them to outside, and now I have a more than satisfactory spray booth. (when I am spraying, I don't even get a hint of paint smell, and that is with lacquers!)
Before I went this route, I looked around for an ideal bathroom/kitchen vent fan and just couldn't find anything decent.
The fans like the Dayton would be ideal, but you will be spending money for those.
You could look on E-Bay, on occasion you can get a used hobby spray booth for a very good price!!
Here is a link on another idea for a booth:http://www.interlog.com/~ask/scale/tips/booth.htm
Anyway, good luck and I hope you get it right.

The computer fans should be alright, it just depends on were you have them mounted, as well as the shape of area leading to were they are mounted. usually they should be placed at the top or directly below with a fluted gate area. I'd draw a diagram, but I've got to go to work.

I suppose I need to get a spraybooth myself...at the moment I use a shed with no ventilation :frog:

I can't think of how to design a booth though, any plans?

*edit* didnt see that link!

well it works.. but i think maybe my box is too big because i get some overspray coming out..

i think i'm just going to get a range hood and build a box around it! should be good

Well, if it is any help, the cabinet part of mine is:
14" deep
20" wide
16" high
This gives me plenty of spraying area for spraying my models, and I don't have any fumes coming out of the booth, I also don't have an over-spray problem.

oh mine is much bigger

24inch wide
24inch deep
and the fans are mounted on the back but it's angled towards the front

i'm going to cut down on the size of mine
and use the range hood
i think it's the best solution
since it's 50CDN which is cheap, my 2 120mm fans are also 50 cdn total...
plus the range hood comes with a light so it's coo

I used a 60" pantry cabinet from Home Depot, use the top shelf as a booth, 2nd shelf holds the CO2 tank and regulators, and the exaust goes into the bottom where a Dayton fan sucks the fumes through a 5 gallon bucket filled 1/2 with water and charcoal filters (fishtank type). I can close it when done and it looks like a cabinet. The total for all this and the lights was $220.00 and $98.00 of that was the fan. DO NOT USE EXTRACTOR FANS DESIGNED FOR KITCHEN/BATHROOM USE! AS THE EXPOSED CONTACTS USED IN THEM ARE A SERIOUS FIRE HAZARD WHEN USING PAINTS!!!
Play safe folks!
;)

ahem....most kitchen extractor fans use a brushless motor (cooking grease/lard/oil IS flammable) and carry a UL label.

bah, i was doing some research, and i found that AC motors dont use brushes like DC motors, so it should be fairly safe to some extent..

but don't quote me on that, this was just a fairly quick search.

so, now i'm going to use a cheapie 180cfm range hood and see how that goes!

Most kitchen range fans pull 200cfm, you need atr least 500cfm. I have a formula somewhere that takes everything into account, like size of opening, how long the exhaust hose is etc.:)

Umm, "spark-proof" is a different rating than "brushless", which doesn't make it spark proof. Paint (especially lacquer) is far more flammable than cooking oils with a much lower flash-point. UL ratings are for intended applications and I could be wrong but I doubt Underwriters Labratories tested kitchen extractors for use as paint booth blowers.

Veyron, for what i need it for, 180CFM should be plenty.. the booth will be small..

I'll have to agree with you on that point!
