Anyone got a recommendeation for a cost effective, spray booth with extractor fan? I'm sure that, given time, I could make something, but I've so little time, at this point, I'd rather buy something. Ideally I'd like something that I could set up in the house and extract the fumes through dryer house out of a window.

Here is one affordable and I heard good things about it and it works good. http://www.ebay.ca/i...=item4ab5dfe9fa

Use a old hair dryer, take the heating part out, make a box, run a hose out the window,

Not sure I would trust such a set up.

There are reasonably priced already assembled spray booths out there that take the guesswork out of which motor to use and how to vent it.

If you do decide to build your own, do a forum search on the topic and there should be multiple posts available for viewing.

I built this over 20 years ago and I'm still using it, Two Explosion proof Fans pull paint fumes out through filter the pic makes it look small but its Big enough to do 1/16th I've even done a 1/8th trike in it.

This last example is very interesting, and roomy. Thanks for sharing.

Like Mike expressed, if you don't want to build your own, I also recommend a Pace booth. It's American made, and a quality unit. The small unit I believe costs less than the booth from Micro-Mark.

Ridiculous and dangerous. You need a shaded pole or "squirrerl cage" blower motor. You never want to pull the vapors through a conventional electric motor. One little spark + some flamable vapors = a trip to the ER. Find a a blower with the motor outside the airflow.

Having recently bought a spray booth, I can recommend the Artograph Line. The smaller version can be found (http://www.chicagoai...stmospbofr.html) under $200.

The larger version includes two extractor outlets so you can vent the fumes outside, which it rather handy, unless you have a cat that thinks he will stick his head in the garage vent! I agree with the post about not building one yourself, unless you are in the HVAC business. Not saying you can't but there are guarantees if something goes wrong.

Here's the one I've been using about 13 years spraying HOK products and flushing my guns with Lacquer Thinner,

The Bathroom Exhaust fans are quick and easy to change out,
The fans cfm empty the booth in less than a second

The booth is not constructed of C4 and I do not use natural gas as my air supply for the AirBrush.
I just love alarmist remarks against building your own Paint Booth instead of "buying" something that puts bucks in another guy's pocket,
The Government even has a booklet of Basic Skills instructing people how to walk by placing one foot in front of the other







2 of the ducts running outside before the third fan was added,


Manufacturers do not want possible consumers to build anything themselves.
However, good old American know how prevails.

Absolutely not! Hair dryers and heat guns use motors having brushes and commutators--not sealed either--and that in the air stream coming out of a home-made spray booth can be a recipe for disaster! Additionally, those units lack the CFM capacity to really do much good.

Seriously, a spray booth is SERIOUS business, and a tool I highly recommend for all the reasons that have been enumerated on these forums. But, it's very important that it be designed properly, for safety and efficiency.

Regarding Pat's homemade bathroom fan booth...

Aren't bathroom exhaust fans "explosion-proof," or brushless? I mean, hairspray is pretty flammable. Would't bathroom exhaust fans have to be the explosion-proof kind, per building codes? Wouldn't they be ok to use in a homemade spray booth?

Just asking...

I know one way to find out........but I would rather spend the money on something that someone engineered properly.

The same could probably be said about kitchen range hoods too Harry, afterall they are designed to extract fumes and are subjected to grease, but how many times do you hear about kitchen fires that start in the ductwork? I have seen and heard of many!

If I can afford $25 model kits and $8 cans of Tamiya spray paint, then I can afford $200 for a properly built and engineered spray booth, even if it means fewer kits and spray paints.

I could use my weedwacker to mow my lawn, but isn't my lawnmower designed to do that? Just Sayin!

I've not seen any notice on a bathroom fan package indicating that they are explosion-proof, Harry. However, due to the humid environment they generally work in, their motors tend to be induction, or brushless motors. In any event, bathroom exhaust fans don't have much CFM capacity, and if one is trying to vent out of doors completely, chances are the inner surfaces of a dryer or other sort of vent will slow the air going through down dramatically.

Just a thought.

Range hoods do have explosion-proof motors. When one hears of a stack fire in one, it's generally from a source other than the mofor--which is why when you go into a McDonald's--if you look closely at the french fryer station, see the exhaust uptakes, they have those rather sophisticated baffles on their bottom end--should a fryer flare up on fire, the baffles help to keep the flame out of the exhaust stack.

Guys, I fully agree that buying a "real" spray booth is a better idea than building one yourself. I was just curious about the bathroom fans being "safe" for a homemade booth. I also agree that a bathroom fan probably doesn't really have the muscle to do the job when used in a spray booth.
