Explosion-Proof Fan for Spraybox?
 

Can anyone point me in the right direction for obtaining one of these for spraybox usage?

try Grainger!:uhuh:

I bought a large one from here http://www.supplydistributors.com/

tell him what you need how bid etc. and I'm sure he can find you something

What am I looking for in terms of CFM?

I am also building a new one. Currently use a bathroom fan in a plastic bin. Works great, but want to upgrade. I am going to use 2 or 3 230 something cfm axial fans. I don't want to give exact details, but if you research all of the availalble lure building info out there I am sure you will be able to find them That is how I did it and now have 12 fans on hand to experiment with. They are out there real cheap if you do some looking around.

where are you using it? cellar?garage?shed?
do you have air coming in to replace the air being exhausted out?
are you talking about maybe a 3'wide x 2' high spraybooth just for plugs and small stuff? spray cans like auto touch up paints that may combust?

maybe you need 150 cfm minimum

think about it, a bathroom fan is 60 cfm for a 4x6 bathroom and 110 cfm for about 6x8 or 9

so I'd start with 150 and go as high as 250 depending on your makeup air( you don't want to suck air backwards from your chimmneys or furnace flue.).

• Basement.
• Air coming in through vent in the room in winter, through window in summer.
• Yes, 2x3 just for plugs, etc.
• Yes, spray cans that may combust.

Thanks for the recommendations for CFM.
