I am looking into building a spray booth. I figure I can build it from sheet metal and use metal duct work to remove the spray out of the basemen. I’m having trouble finding the right blower/exhaust fan for this purose.
The size of the booth woiuld be roughly 24"WX12"DX24"H I will have a filer planning on using 1" furnace filters unless I find thicker. I am mostly using acrylics but do manage to use solvent based. I also use solvent based primer and clear coat so I do need to use a spray booth. Much help to anyone who knows where I can get a fan at a decent price.
Or maybe someone knows the part number and cost to the one that testors uses in their spray both thank you.
About 15 years ago, I bought a spray booth at a Iron Rails hobby shop in Kenosha, Wi. I don’t remember who manufactured them. The big thing back then, was getting a spray booth with a sealed motor . They were referred to as explosion proof motors. The problem being a spark from the motor could ignite fumes from the paint.
I use the 1inch fiberglass furnace filters. I buy them by the case when they are on sale. I vent my spray booth outside using 4inch flexible metal dryer vent hose to a dryer vent.
I use a bathroom exhaust fan and have had no problems. The fan is easy to add a clothes dryer flex tubing to get the fumes outside. Some models have a few small holes for connections and what not. Cover them with duct tape.
Personaly I would consider an explosion proof blower, remember vapors will sink or go to the floor, do yo have a gas dryer, furnice, hot water heater or any thing with an electric igniter or pilot light.
I know there will be some that say I have done this for years and no Promlems, I had a friend that thought automotive parts work on gas boats, he died in a boat explosion and I remember him stating I done this for years.
Sorry ,…Im a tad paronoid with vapors, flames and loud noises…John
I did a Google search for “explosion proof motors” and came up with this information.
Elwood/ Gettys High Performance Motors
2701 North Green Bay Road (also known as Highway 31)
Racine, Wi. 53404
!-800-558-9489 or 1 262-637-6591
Try giving this place a call and explain what you want to do. They can give you an idea of what they have that might help you and the cost of the motor. You can check out their web site too. www.elwood.com
I lived in Racine for 14 years and never knew this company was there.
Everyone thanks for the information I decided last week to just buy one at the prices of exhaust fans. I picked up an Paasche one for under 200.00 brand new.
A Tip on Grainger’s…At least here in Rochester NY you have to have an account with them to buy anything from their stock. Imagine my disbelief when I found the replacement fan motor for my 40 year old bathroom fan at Grainger’s only to be told I needed an account!!!
Come to find out that my Company that I work for does have an account, and as long as I had a valid Company ID, that was good enough for cash and carry…Whew!
Essentially the same thing I did, and have been using for many years. I do use solvent based paints (Floquil) and the thing about a sealed motor is a bit overdone. Get the MSDS on the paint(s) you’ll be using and look at the LEL (lower explosive limit) for them. The concentration that it would take to ignite the fumes is so high, your air purifying respirator wouldn’t be able to provide enough oxygen for you to breathe. Most of these type recommendations are on the overkill side, especially for something used intermittently like for hobby purposes.
