Spray Painting Booth

Any thoughts on this Badger version from Amazon?

Also considering home building one, but have been unable to locate a fan without the motor in the airstream. I will probably never use anything but acrylic paints, but would prefer to be prepared just in case.

I love how they illustrate it with the exhaust duct aimed straight into where your face would be. Definite error in the photographer's studio. I hope prospective buyers quickly understand that's not where you put it! I've seen this exact booth with house brand names, but even with the Badger branding that's not a bad price.

HOWever... to your concerns, from the descriptive text down at the bottom:

Not intended for use with Hazardous Materials, Flammable or Explosive Paints or Materials

They have the motor in the exhaust stream, too, probably just some high-flow axial fan normally used for cooling electronics. Personally, if you're inclined to build your own, a $15 box fan won't be a hazard even with solvent-based paints because the motor is a synchronous A/C type. No brushes, so no sparking, and with that much volume being moved anyway, vapor density will be nowhere near hazardous levels.

I actually own that very booth and if you spray acrylics it's ok. They ship it with 2 air filters - you get better airflow if you take one off. It won't pull air Mike's box fan will but I still use it. Hardest part is keep going the exhaust port in the window I use.

My setup uses a dual squirrel-cage blower from Surplus Center.  It uses an induction motor (not sparks) which is also outside of the air stream. It is also powerful and relatively quiet.  I checked and they don't have that blower available anymore.  But they do have what looks like a single-blower version. See http://www.surpluscenter.com/Featured-Items/160-CFM-115-VAC-JAKEL-PP-355-BLOWER-16-1509.axd

While it is not inexpensive, it has features similar to the one I used (but half as powerful).  I would recommend it as a spray-booth exhaust fan.

What kind of flow is 160 CFM, in layman's terms?  I need a fan for the booth I built.  Originally it just had a crappy exhaust fan from a stove vent, which barely moves any air.

What kind of flow is 160 CFM, in layman's terms? ...

Visualize a 4 x 5 foot bathroom with the standard 8' ceilings. 160 CFM will theoretically exchange the air in one minutes' time. It won't generate much of a breeze, however - a cheap 20" box fan on "high" is good for 2-3000 CFM.

[peteski]

Actually the lack of breeze is a desired feature for paint booth air-movers. The last thing you want when you are painting is breeze blowing by your model depositing dust in the wet paint or deflecting the spray coming out of the airbrush. 

Is there a CFM rating for the fan included in the Badger booth?  If it is a standard computer enclosure fan then I suspect it is much less than 160 CFM.  The dual one I have (rated 320 CFM) generates string air stream on the exhaust side (when I stand by the basement window where it exhausts)

Where do those tiny fans exhaust the fumes? Back into the room? 

[daniel_leavitt2000]

I use it only with non-toxic acrylics. Spent the last week overhauling my paints and tossing anything that looked dangerous.

Are you sure that the fumes are non-toxic?  IIRC, the non-toxic designation usually applies to the dried paint.  The solvents in those non-toxic paints usually contain alcohols or glycols among other chemicals.

LOL!  And I played with unpainted lead toy solders when I was a kid. 
So your spray booth is basically an "overspray catcher" with some induced airflow through it?

So that's what you told the RA?

 

Daniel, saw your set up. I may mount the fan to a similar style "booth."  Finally got the fittings to run my airbrush of my nail gun compressor tank. Just don't want to spray most of the model bench.

Also debating putting a T junction in at the drier vent and running an exhaust hose from the booth to that spot. I wouldn't use the drier at the same time as the airbrush, so would I have to worry about flammable buildup from the vented overspray? Drier exhaust temps at the vent are around 95 degrees.

This is my set up. The plans are on the web somewhere can't find them, but there out there. but i used a hepa type air conditioning filter plus a large particle filter from making trees days, I've been using it for about a year , It filters out most of the particles but some fumes still get through but not enough to worry about, I also found a dental rolling tool cart (not pictured)
that it sits on that stores all my paints, I use a Nitrogen tank for air brush work and Rattle can a lot of stuff as well. over all very happy with it, when filter is dirty I just rotate it. One day I may fit a second fan into it but for right now it works just fine.

when it was new!, Rotating table got from Arts store on 50% sale coupon


pink foam supports filter.
