Model Expo Spray Booth - Annoying doubt!

[panzer360]

Roncla and every other user of this spray booth, i asked them if this Spray booth is safe to use with flammable paint and the reply was:

"Book says NOT to be used. A spray booth for flammable paints would be required to have a totally enclosed fan motor which is ,of course, more expensive."

So for the paints i want to use Alclad 2/Zero Paints i just bought a useless spray booth and since i bought it from a store in UK and im from Portugal it will be very difficult to get a refund.

Don't be so downbeat, you can still change the fan motor for a better one.

That's worth trying. If it looks like the booth uses a computer type fan then perhaps swapping it out with a more powerful one can help. I've seen these fans go as high as 80 cfm. Try your local electronics store. With any luck you may not have to do any rewiring as these fans tend to have a universal connection.

You can also try one of these

This can be placed into your 4 inch (100 mm) exhaust duct for an added 80 cfm boost. This appears to be a computer type fan encased in exhaust ducting which should be safe to use, but verify that this is the case before you purchase it. This one costs about 13 Pounds.

Just to clarify something: The spec Model Expo gives is 3 cubic metre/minute, not 3 cubic feet. That equates to just shy of 106 cubic feet, does it not??

Great catch! You're exactly right.

Sorry, panzer360, as I've seem to have caused you some unnecessary grief over the performance of your booth. At 106 cfm (3 m3/min) the face velocity is about 73 fpm (0.37 m/s) and should have sufficient power to overcome the friction within the exhaust duct.

It looks like I have been playing with fire then as I have been using the booth with Zero paints and 1k & 2k paints for awhile now.

There are no warnings on the booth anywhere that says using flammable paints could cause combustion.

It was only when I read panzer 360s' first post that I looked deeper into my instruction sheet and found on the last page amongst the usual don't use when impaired, dont use around children ect ect that it says for health reasons not to use poisonous or flammable paints.

I guess it would be unhealthy to have it combust in your face. The booth should have warning stickers on it if there is a danger of combustion as instruction sheets are invariably not read or tossed aside and lost.

Exactly thats the thing that annoys me most is the fact that they sell this spray booth without any warning about the dangerous of this spray booth with some paints.

We should allways make a research and see others opinions when we buy something, but in this case they should give us this type of info and tell us for what this type of equipment should be and shouldnt be used.

I though the whole point of having a spray booth was to extract the fumes from dangerous and toxic paints..?? Why sell any spray booth as a spray booth and yet it is unsuitable for dangerous paints..??? I would say all paints are dangerous in some way if you are breathing the fumes in....
I would certainly look into changing the fan as it seems that's the only problem with using it with flammable paints. Change the fan for a shielded one that is suitable for all paints and your problems should be solved...

I agree that it may be prudent to look into changing the fan even though I have not had any issues while using it with flammable paints. I am looking at the booth sideways now and aren't entirely comfortable with it.

I do have a larger booth out in the garage which I know is safe so I'll revert to using that now the weather over here is beginning to warm up.

Hello again, anyone know a safe spray booth with a brushless motor or any spray booth safe for paints like Alclad/Zero paints?

I tried to find anything to swap the fan of my useless spray booth but found nothing.

Yes, this one...

I still don't think its a useless spray booth as I have carried on using my identical one with Zero paint and 1k PPG Dulon Premium automotive clear coat with out any issues. It does what I expect of it which is extracting the overspray and fumes.

I can't believe that if there was a significant danger of it igniting the fumes the manufacturer hasn't put a warning on the packaging and on the spray booth as well. My one has no warnings on it any where.

I am only using this spray booth for airbrush work though and have a larger squirrel cage booth set up in the garage for aerosol use and when I'm using a HVLP touch up gun.

I do keep fire extinguishers within easy reach of both my booths and all my paints

Thanks Steve. Unlike the modelexpo site in the GraphicAir site they clearlly say for what we should use the spraybooth and give us all the info.

The graphicair spraybooth is the one i should have bought in the first place. At least it seams more suitable for what i want...

Even them selfs said that we shouldn´t use this with flammable paints, so if i don´t want to use acrylic paint with water is a useless spray booth for me.

Modelexpo:

I just looked this up on their site. This would be useful info to include in the description not just the basic description given on the site.
Seems nice enough, just not as good as it should be.
