Spray Booth Question: Paasche Instructions and Cautions

[Ragtop Man]

We are in the planning stages of how the interior of Garage Majhal will be fitted out. Long backstory on this, but we moved to a completely finished home and my hobby stuff went to turnaround; the deal to sign (for me) was that we would renovate/build on the second floor of the garage for hobby work. 

Plans have room for both my own 'slop sink' and a spray booth, with a short (less than 3') run to the outside for venting.  So far, so good. 

Paasche has a really good sized booth with twin (!) outlets, (pricely, but I'm liquidating a chunk of the collection) but is quick to caution that it is not for use with flammable/explosive hobby solvents and paints. Never mind that I've had a Testor's MM booth from the 90's that never had an issue, and that is positively rickety in comparison.

So the question to the group: Is this lawyer-ese for "yea, you can use it for that but don't sue us if something goes wrong" ... or... "No, really, don't - you will blow this to kingdom come." 

I'm taking a guess that true explosion proof fans are very expensive - as well as outlets, switches, lighting, etc. and it just isn't practical at retail to offer up the gear this way. 

So to the question - if I'm using Rattle can Tamiya or automotive finishes, airbrushing MCW, Tamiya acrylics or decanted automotives ... is it no bueno? There will be windows to crack, as noted short runs to exterior and pro installation. Anxious to hear what you are thinking, as always appreciate the advice.

Explosion proof fans are not expensive. A 12v bilge fan and a power supply are all you need.

Here's a thread about paint booths, and pictures of the one I put in my basement, using the bilge fan.

if its being installed by a pro i would ask them. they will be putting their name to the work and may have an idea that will work better for you. it could work out better for you to get something custom built in. that way you can design it to your needs and if its built in add doors to help keep it clean. if theres already electrical being done its only some extra wires and maybe 2 hours. and build bigger than you think you need, extra space is always good

You might check out Pace spray booths.

I've had the Pace Mini for a few years now and love it!

I have a Paasche booth. I love it but since Paasche has no real knowledge of how you're going to install it I can see why they say don't use this for flammable paint. I think you can....never stopped me but if I do blow up, my wife might not be able to sue.

Ditto!

Post script: Their tech rep responded that he uses it with a lot of the same finishes the 'we' do - hobby products - and does not forsee an issue.

However, they sell products that must comply with commercial fire and insurance codes, so those are geometrically larger and more expensive. 

IMO, the ideal solution would be one of the badass rug-lifting fans with a high velocity steel duct on a short run. In the meantime, a quality commercial booth is probably the best solution. Since I've got a bit of a big scale freak on, 24" is the minimum and 30" would be ideal (have a few planes in the queue, too.)
