What fans for venting paint booth?

[nightfighter]

Probably covered before, but want to see what's available. going to be venting outside. Will need to be able to handle flammables as I will probably be painting more than just plugs.

Also looking for a dust collector. Not going to hard pipe at this time. Plan on dragging hose to machine I am going to be using.

Thank you for the input.

Check ebay for axial fans..... Be patient and some good ones will pop up...

Ross what size tube are you planning to vent.... I found some quick disconnects and some dryer vents that combined into a spray booth.

I can provide pics if you want to see them.. Pm me your email since I don't know how to post pics from my phone..

To be able to handle flammables you need to have a motor completely separated from the plenum of the air flow. That is fire code.

Ross don't #^&#^&#^&#^& around with stuff like axial fans. If something was to happen your insurance is null and void.

If you wanted to put together a small booth I'd buy a big squirrel cage fan rated for 4" dryer pipe. mount it inside a sealed box with the motor outside the box. Should be metal pipe...

But that don't cover the insurance part still.... BOOM

been using jenn-air drown draft fans for spray cans and airbrush and lead fumes for years.....check the bay for used...they have like an 7-8" intake an the outgoing is 5"...hardly hear the things run,but do sux well and their made for grease an smoke that go boom.

Ross, here's what I use for the dust collector problem.


Delta 50-850 1-1/2 HP Dust Collector 1200 CFM

salty covered the concerns for your spray booth... Grainger offers several options for blowers capable of handeling flamable vapors...
I use an old range hood.. but only spray water soluble paint through it because it is an air over motor... as i've said beofore.. primer and clear coats are sprayed outside..open air..

for a dust collector... any system capable of 650-850 cfm capable of 6" of staice pressure will handle single machines ( midi lathes require approx. 350 actual cfm to keep things reasonable) is fine for on spot collection... but are not capable of hard piping as the S/P loss would be too great... I advise anticipating the future and going a little larger.. Penn State industries is having sales on some of their models...

So if your painting with a water based paint, such as createx, you shouldn't be using axial fans?

Shouldn't be using axial fans for anything. All water based paints have solvent in them. Createx has ethylene glycol.

I have a Pasche spray booth.. Axial fans...

This is what I bought.. dbl vented outside.... If Paasche's insurance company is ok with the fans so am I ...

Obviously if your doing thousands of plugs then a much bigger booth with explosion proof fans would be the way to go...

Nope don't make a difference. You can look it up online yourself. I can guarantee you a paasche booth does not meet nfpa fire code standards.

Don't care. I'm just telling you. I've said it for many years. Someday....some one will go boom...... Just don't be the one pse.

Ask your insurance company if it's ok to have a spray booth in your house. Why risk losing everything you own?

This is exactly why I posted this thread. Some will say Scott is over the top, but his point is well taken here. I want to do my due diligence before I spend any dough on the blower. So in looking at brand names to consider, I have seen the Jennaire and Grainger mentioned. Grainger's spark resistant blowers are all over $1000.00...... and not even sure that covers explosion proof that we are trying to identify. I doubt Jennaire will qualify as being explosion proof, but am looking into it. Again, if a reasonably priced blower to fit the bill is out there, let's identify it.

[stripermaineiac]

Scott hit the nail on the head. the NFPA regs are very good tools.Any motor that sparks in any way must be outside the vent chamber. To prevent explosive mixtures the vent chamber must be large enough not to allow this based on the ammount of airflow produced and the mix of combustibles in the airflow. remember coffee mate will explode in the right mix.If you have the motor where it and the fumes can mix it will go boom in time. I've fought fires caused by this.There are systems out there to do this safely. Remember it's yours and your familys home. If you can't do it right find away to paint outside.You'de be better off using 2 box fans blowing air from behind you out an open window in front of you to blow the fumes outside instead of s#^&#^&#^&#^&#^&g them out the window through the fan.A long time ago I went to school for this. the summer after I graduated I rescued a freind of mine from his home autobody shop that blew up with him in it due to poor venting and the wrong type of fans. I paint outside and dry inside.Ron

Get a fireplace and spay paint into the fireplace. Burns off the flammable fumes, ventalates properly outside, good suxxion. Problem solved

What Ron says is true. And it's not just the motor....it's the FAN itself. It cannot contact or possibly contact anything that can cause a spark between the fan and the plenum. They make the blades usually out of a non sparking alloy.

FREAK

well if you had a few plugs laying around she was memorized. I happen to get a peek at a couple plugs you dropped off to someone last year at MSBA and they were UNREAL....
