doing some bodywork on my mini atm, ive found that dust sits in the air, and also, if i paint anything, the paint can also sit in the air. i was thinking of putting a kitchen type extractor fan in the back door. I also just was thinking, if i do, and i spray thinners in the air, is there any chance of an explosion?
is there another type of fan that i need?
thanks

I was just wondering the same thing. I'm intending to build a small spray booth for painting brackets etc, with a bathroom extractor to the outside world.
Most kitchen or bathroom extractors seem to use induction motors, which means no brushes and no sparks, but they aren't specifically rated to be explosion proof. Those commercial jobbies in your link are probably similar, but bigger and better suited to shifting a whole garage worth of fumes.
One thing to remember though is that your switch (which will create sparks) will be in your garage too, as will all sorts of other sparky things, like light switches and compressors, etc. They might be a bigger problem.

in my mates paint booth, the light he had where strip lights in plastic casings. I wonder if that was to do with the fumes?
But ive gone for a cheep 12v car rad fan, and a PC atx power supply, so all in for about £34 but also i can use the Power supply to run 12v lights in the garage or other things.

I recently built a bench with fume extraction for my workshop. It's basically a copy of the fume extraction booths people use for spraying alloy wheels or other smaller painting jobs that don't necessitate a full spray booth. For extraction I used an 8in inline centrifugal fan similar to this which then goes into 8in ducting to the outside. It shifts a lot of air (probably overkill but better that way than not enough), runs off a mains plug and is quiet. I'd go with something like that, or a 6in one, depending on what amount of extraction you need. Domestic bathroom fans and the small extractors used for hydroponics don't really shift very much air but I guess would be better than nothing. |

looks really good!

I wouldn't use the 12v fan. Being DC it will have brushes and therefore be very likely to ignite any combustible gases going through it (which paint fumes are).

i thought about that, but ill put the motor on the outside so ti should flow over it not into it, and also, ill have a look at the bearings and construction. It should be designed to be water proof being sat on the front of a car rad, so, i don't think fumes will be able to get in there.

Paint fumes won't ignite.
Your link to the first fan was the best one, but you really need more power than that. Rule of thumb is you need to remove the entire volume of air in the workshop every 60 seconds.
PS, putting a filter over it will kill any extraction.

right thanks. i put the 12v one in the door and it does move the air it has to be said its not bad but its not the best! I have a use for the fan, i may buy another.
I am only painting the mini in sections, doing to each seam as the garage isnt that wide. So, its not like I'm doing a full shell in one go. The worst part i think will be doing inside of the car, but i may do that in sections too.
thanks!

Well, 2 pack can damage your health doing a small part as easily as spraying a car. Get the big fan.
Painting inside a car - get an air fed mask.
