Paint/Spray Booth blowers/fans

Mits,

 

Looks like a great fan just be sure it has induction motor (brushless) to reduce sparking. Speaking of that 3dog I got to diagree with you on using a shopvac. Those motors have brushes in them electricty is transfered to the stator via carbon brushes this creates sparking and the potential for an explosion. You can see this by starting the motor in a dark room. Now if you could find one with induction motor all is good.

 I Vent my fumes right outside the window and have never had any paint on the side of my house. By the time it gets thru the fan it is dry and thus will not stick to anything.

 

Cheers

I called the local Grainger store and they wanted $115 for model 4c444. They did not have it in stock but a nearby city did. The sales clerk talked like there would be a shipping charge even for delivery to my local branch. Adding shipping, tax, building materials, and various parts to fit everything together easily gets into the range of buying a commercial spray booth!!!

Evidently Hydroponics is a hobby that also uses shaded pole blowers.

Here is an example from "Maryland Hydroponics". They seem to be one of the cheaper hydroponics places I found.

They also have the flanges that adapt the retcangular output to a round one for dryer vent hose.

Ok, how often are you going to be using the paint booth you are building and would you really like to fully utilize what you are spending that sum of money on?  The whole purpose of the blower, fan, or what ever you want to call the thing you hook up is to get the fumes out of the space and do so without causing an explosion.  For a paint booth you do not blow air into it to accomplish this desire.  You suck the air out of the space.  You do not want to suck a high volume of air by your model while doing this for dust and such is in any air.  It will get stuck in your nice wet paint job.  A good piece of equipment to accomplish this, have easy maintenance, easy hook-up, and be useful for more then just accomplishing your plastic model hobby needs is nothing other then a good brand of a wet/dry vac.   Try finding one that has a pretty good size hose diameter on the intake and exhaust ports.  These things will have accessories you can purchase such as extra lengths of hose. all shapes of attachments to those hoses, and etc.  Now match your venting pipes (pvc works great) to route an exhaust duct to where you want it and make a filtered air box that will let you hook the intake hose of the vaccuum up to it on the bottom back edge of your paint booth or the floor of the paint booth.  You take the time to fit couplings right you will not even need hose clamps for the vaccuum hook-up to the pipe system to have a tight fit.  This lets you grab the vaccuum for other odd jobs around the place as needed when not painting.  Be sure it is a wet/dry vac as the motors on these are sealed completely, along with electrical stuff, to prevent you getting shocked while using it in a wet condition and prevent that use from ruining the vaccuum.  The other side of the coin for this feature is what you are looking for:  explosion proof to the vapors coming from the paint.  Where ever you decide to place the final outlet for the exhaust be sure you are not dumping your exhaust out in a place that you do not want damaged from paint overspray.  Some paint particles are going to escape through it even with filters in place.  Along that line of thought be sure the normal wind will not be catching those particles and blowing them across things you do not desire to be color changed as well.  gregg

I remember now seeing your post/pics but forgot where I saw them. What are the dimensions of your booth? I cannot tell from the pics but is it vented outside or are you relying on the filters. My plans are very similar to yours. I believe I'm going to use a metal/wood adjustable shelving unit as the basis for mine. One of the shelves will be built up to make the spraybooth. The others shelves will hold supplies and equipment. I've read Grainger will only sell to established business/commercial customers. Do they ever make exceptions? Thanks

Actually, becoming an "established Grainger customer" is easier then signing up for renting movies at Blockbuster.

All you gotta so is think up a nice name for a home-based business,and go down to a store, and fill out a short application, indicating that you will pay by cash or check. For my home-based business, I simply use my last name and add "Company". That will save you having to put up with a credit check.

Their only requiremant is that you buy something else there within the next year, which should not be a biggie for any scale model builder.

OK?

I'm new to airbrushing and I'm building my own booth. My question is, how do you get the air to "suck" through the filters? Do you mount the side part by the cage where the air comes in on the bottom of the booth and run duck from the output of the blower? Can you reverse the fan so it does suck instead of blow? Thanks for the help.

It's 29.5 wide 30.5 high 23 deep. Check a local cabinet shop or lowes ect for seconds or customer rejects they sell them really cheap. Funny how a 12 pack of beer offered really reduced the $$ for me they are sick of these rejects taking up space. Yes, it is vented outside as the fumes are BAD. Don't worry about paint on the side of the house by the time it gets outside it is dry. Make sure your wood shelves are sealed as they can make dust ect and other stuff that is bad for the finish. I sealed my wood with 3 coats of water base white paint to seal everything and it makes it easier to wipe up messes.

 As far as grainger goes they have lots of warehouse and anybody can go in and buy stuff. I just called and payed for the order using my credit card but our company has a purchase history with them. If this proves to be a problem let me know and I will see if I can help.

'Dude,

 

Check out my booth:

I used the Dayton model 4c444. It will say discontinued but they had lots of them in stock at Grainger Flint Mi store so you should not have much trouble getting one. A quality blower is very important if you are going to use flammable base paints and well worth a few extra bucks to eliminate a explosion hazard. Just be sure to do a good grounding job on all metal parts.

 

Good luck if I can be of more please feel free to ask.

 

Cheers

Check on ebay.  they go for fairly resoanble prices for the larger CFM blowers.  Stick with Dayton, if you can help it.
