AzTom,
Regarding your threat to curtail the 1st amendment here by deleting the posts offering useful info that you aren't privy to.
Seems like recently our U.S. Constitution is being treated like it came with an eraser to be easily changed.
I'm actually amused at your forceful and adamant replies, and would never ask for them to be removed.
Why would I, I could care less??

AzTom, I'm just making a suggestion here but maybe more fiber in your diet might be necessary.

All that talk about worshipping National this and National that Agencies tells me you are exactly what they want, people who will do what they say and not ask questions. That just does not apply to me.
Hobbyists and Artists not only ask questions, they innovate, they invent, to improve their craft.
Some of us don't need all those Govt. regulations and I think your time would be better used not trying to scare people.
Heck, you can fingerpaint your Models for all I care.

You did finally confess that, quote, "YOU HAVE NEVER SEEN A BATHROOM FAN EXPLODE WHILE BEING USED IN A PAINT BOOTH "

Honsetly, I put my Tutorials out there for anyone to use them.
It just amazes me when someone else, through no experience of their own, tries to quash a thought because they heard from someone who heard from someone, and so on and so on.

I can say, I BUILT THAT and IT WORKS!!!!!!!!!!!!!!!!!!!!!!!!
And, so can many others I've helped!!!!!!!!!!!!!!!!

I made no threat. There is no 1st amendment on this forum, they have very right to delete any post for any reason.

My suggestion to you, lighten up on the fiber and quit spreading the BLAH_BLAH_BLAH_BLAH that those fans are safe for paint booths!

I'm really getting a good chuckle over the cat claws in this thread.  Ya'll fight like a bunch of wet hens.

 

For what it's worth, my two cents is that if you spray flammable materials through a fan that isn't designed for it because you're too cheap to buy the correct kind of fan, you deserve to watch your house burn down...and just because you've been doing it for xx years with no problems doesn't mean something bad won't happen tomorrow.  I once pulled the ignition coil wire off a running engine with my bare hand and found out just how far 30,000 volts can jump...just because I'm still alive doesn't mean I should keep doing it...it just means I was luckier than I was stupid.

 

Having said that, I have a homemade spray booth (with a proper squirrel cage blower), but I need more CFM.  Has anyone seen the fan below?  It seems to be sort of a squirrel cage type blower, and looks to be easy to modify for a custom spray booth.  If it's "explosion proof" and pulls anywhere near the rated CFM, it would seem to be the best buy around, but I can't find anything specific about the motor on the company's website.

It says in the ad that it is rated at 500cfm, but keep in mind that is with no ducting or restrictions. How a blower reacts to those things is important. At $59 I am positive that it is not "explosion proof". That looks like one of those blowers for drying wet carpets, not for venting gasses.


If you really want to spring for an intrinsically safe aka "explosion proof fan" you are looking at a lot more than $50.

Here is one of a similar size for a mere $719

Personally I'd suggest one of the shaded pole blowers from Grainger. Less than $200 will get you enough fan for a big spray booth, less if you only need a small booth. Intrinsically safe fans are really intended for venting highly flammable vapors, gasoline, natural gas and such, not spray paint. None of the commercially available booths use an intrinsically safe fan, most use a shaded pole blower.


This is the one I used on my booth, it is 485cfm. 2ft x 2ft x 16" tall booth, cross flow out the back with a heater filter and 6" ducting. It works great, no overspray or odor using full size spray cans. It is a very well made, heavy duty blower that will probably outlast me.

Escuse me, but my Pace commercially made spray booth uses a GRAINGER squrrel cage blower with a sealed, shaded pole motor!

Yes, exactly. Most commercially available spray booths use the same Dayton blowers you can buy through Grainger. I think that is what I said.

Shaded pole blower does not equal intrinsically safe aka "explosion proof", that is a specific certification, that adds a lot of money to the price. Pace does not use intrinsically safe blowers. To be clear, I did not use an intrinsically safe blower either although it is a shaded pole blower.

Not a lot of info to go on in the ad, but 4m3 translates to 141cfm. It looks like the work area opening is around 12x12", maybe 15x15" (based on the turn table being 7.5") so just based on air movement it is probably decent about venting. The filters could be a problem, depending on the availability of replacements.

The ducting will throttle the blowers capability, but that is a price of portability. If you were to set this up semi-permanently I'd replace it with the shortest piece possible, and try to use straight metal ducting if possible to get the most out of the blower. Flex hose and curves in the ducting add a huge amount of restriction to the air flow, as does using more duct that you need.

Based on the source and the price I imagine the materials quality is poor. For about 3x ($265) the price you can get a Pace Mini-Plus booth which is twice that size, made from sheet metal and uses standard (easy to find, cheap) furnace filters.

Art has a Pace booth and seems quite pleased with them.

So as far as the booth you posted? It looks adequate, but you get what you pay for, and $80 is pretty cheap.

However, consider that the blower in question is a squirrel cage unit, the motor is pretty tightly shielded (encased), and the motor is completely outside of the air stream.
