tabsscale1 Posted October 2, 2008 Share Posted October 2, 2008 Mine is a back draft I used furring strips and made a box and in the back I made a box that holds the Bathroom vent fan that is connected to a dyer vent tube outside. The walls are a plastic shower walls that I cut up and screwed into the furring strips . I use a furnace filter also in the back to catch most of the over spray. I had the furring strips and bathroom shower walls from remodeling my bathroom. Cost was maybe $20 for everything else . Did it all about 15 years ago Was glad i saved that old shower came in handy for this. Would take pictures but daughter has the camera and she isn't here.

brikennedy Posted December 23, 2008 Share Posted December 23, 2008 I did mine with wood and used an inductor for a fan. These inductors are usually installed between vents to move heat to the farthest rooms from the heat source in bigger houses. They have the electrical connections right on the outside so that you can hook them up any way you wish. They are usually hooked up to thermostats and stuff but all you have to do is splice and install an extension cord right onto them. I installed mine about three years ago and have not had any issues. I just ran some 4" flexible clothes dryer vent right outside the house and that's it. These inductors come in 8" and 4" wide sizes, I went with an 8" and bought some reducing vent couplers to go from 8 to 4 inch flexible dryer vent material. Pretty good at sucking all the paint fumes right outside the side of my house!!! How many CFM is your induction fan. Just curious because I want to build a paint booth just like that one.

diymirage Posted December 25, 2008 Share Posted December 25, 2008 How many CFM is your induction fan. Just curious because I want to build a paint booth just like that one. Thanks Brian i just used a 70 CFM bathroom fan build into the bottom of the booth Quote Link to comment Share on other sites More sharing options...
Helipilot16 Posted December 27, 2008 Share Posted December 27, 2008 I used a Toro weed blower mounted in the roof of my booth. It is a little noisy but really pumps out the air (would you believe 250 MPH?). Quote Link to comment Share on other sites More sharing options...
lonewolf01 Posted December 27, 2008 Share Posted December 27, 2008 you got any problems keeping the model in the booth Quote Link to comment Share on other sites More sharing options...
Helipilot16 Posted December 28, 2008 Share Posted December 28, 2008 I would be concerned about using a kitchen or bathroom blower. I read somewhere that at least 200 cfm is needed. My weed blower (used on the vacuum side) puts out roughly 400 cfm. Since there is no venturi effect on the vacuum side with the large opening of the spray booth, you can't actually feel the air move. When I am painting, the overspray (which is directed outside the house) immediately disappears. To avoid the accumulation of paint on the walls of the booth (which can fall back on the model), I lined it with newspaper; which I change periodically.

sliferkiller Posted October 1, 2015 Share Posted October 1, 2015 Hi guys I'm wondering how safe it would be to use a ceiling fan or any not recommended for flammables to paint with lacquer paints. From what I understand, there could be a possibility of an explosion but I'm seeing most of you guys are using ceiling fans which shouldn't be protected from flammables?

Danno Posted October 1, 2015 Share Posted October 1, 2015 Looks good, Gabe. How's it working out? Quote Link to comment Share on other sites More sharing options...
Yenkocamaro Posted October 2, 2015 Share Posted October 2, 2015 Not to start a big debate, as I read the thread on safe exhaust fans for spray booths, but I built one many moons ago(don't have it anymore), and the main thing is, use a sealed motor, not an open one. A sealed motor uses the air running across it from the fan blade, to cool it, thereby no paint particulates are sucked into the motor, like an open one. True, you could go for years with an open motor, and no problems, but, all it takes is one spark from an open motor, and I didn't want to take that chance. I incorporated a channel from wood trim, to slide a furnace filter in, before the motor/fan assembly, to catch the paint particulates, and not allow a paint buildup on other parts of the booth. Also, be careful about the CFM's, remember that the air you are pulling through the booth involves the air in the room, you are painting in. Too much, can bring dust from the room into the booth. JMO, but if you insist on using an open motor, please set up a furnace filter before the motor, so it doesn't clog up with paint. The ideal build, is to have the motor mounted outside the booth, so its not subjected to paint, or fumes. Cheers,Lance 1 Quote Link to comment Share on other sites More sharing options...
AzTom Posted October 3, 2015 Share Posted October 3, 2015 Good point Lance. The squirrel cage type fan is what you want to use. Any motor in the air flow has a chance to fail and cause a spark. Having been in the electrical business for thirty plus years, I have seen way too many bath fans and kitchen hood fan motors burnt up. They were doing what they were designed to do. Paint and thinner build up on any open motor is, in time, going to fail ... How lucky are you? Quote Link to comment Share on other sites More sharing options...
Miatatom Posted October 12, 2015 Share Posted October 12, 2015 Here's mine. It's undergone several revisions. I should post new pics. Fully enclosed down draft. Quote Link to comment Share on other sites More sharing options...
my80malibu Posted October 13, 2015 Author Share Posted October 13, 2015 It actually worked out very well, I did just recently scrap it though, it had been outside for the last few years under the Patio, and was starting to show its age, then as luck would have it I ran across a Paasche paint booth in nearly new condition on Offer Up, for a very good price, and I scooped it up.

This is almost exactly the same set up I've used now for a couple of years Bruce. I think I spent a grand total of $35 on the whole thing and it works like a charm.

mrmike Posted June 27, 2019 Share Posted June 27, 2019 I found these plans on a model railroad site years ago and I have used them to build my paintbooth. It's not perfect, but it does work rather well. I also use it for a photobooth by adding large sheets of colored poster board. Like I said, it's not perfect, but it does work.
