Suggestions on mounting blower to spray booth?

Cableguy....you wouldn't happen to be using the same (or similar) blower as the one Vin Man used in his booth, would you?  If so, I just purchased a similar blower with the same problem.  I think I may cut the output flange flush and drill two new holes (to secure the flange) and then I can mount the unit directly to the booth, preferably in the center.  I am assembling my booth tomorrow, so hopefully I can let you know how it goes and if it works.  I may be able to get some pics, not sure yet.

Oh boy...did I hear my name?

I already had an idea for centering the airflow if my "corner" mounted blower didn't work. (I never did it because my booth works fine the way it is)...

Mount the blower in the corner but create another 2nd backboard. This 2nd backboard would be 1 or 2 inches separated from the original backboard. (Seal it up good) This second back board would have holes, wherever you want the air to get sucked in. In other words, you are creating a vacuum gap that will allow you to redirect the air intake.

Another option - I stole this from another guy's idea. Get one of those plastic Tupperware or disposable plastic containers....the kind you might put a sandwich in...but you might need something bigger. Cut a square hole in the backboard (just big enough for you to put the container in. (visualize the container's "bottom" sticking out of the back of the booth.) Seal it all up good. Cut out the bottom of the container and mount the blower's intake to the bottom of the container. (Visualize the intake screen on the "inside" of the container and the the blower body on the outside (bottom of the container)...plastic sandwiched in between) Now, you should have made plenty of room for the blower. Unless you build some sort of "platform" for the blower to carry its weight, it will be near the bottom.

...But, mine works fine the way it is. I was rattle canning some enamel for a wooden base the other day...and it was pulling the fumes in fine. (The way my desk is organized, I do most of my painting in the opposite corner of where the intake is.)

The baffle suggested by Vinny is a good idea. My blower is center mounted, but I wanted a distributed air flow, so I put in a baffle board similar to his description, and it works fine. This is the way industrial booths are usually (or should be) made.

Great tips, Vin Man.  I think I purchased the same blower you have on your booth and am going to start the build tomorrow.  I have my plans laid out and hopefully all goes well.  Thanks again for your tips and advice.....I have saved some serious $$$ and get to bust out my power tools tomorrow!

Yup, I bought from the same place as Vin Man, but I got the 265cfm blower instead of the 465cfm.  My original thought was to build a small booth, but that didn't happen....sssssoooo, I may end up with either a second blower or ordering a larger blower.  I'll see how this one does first.

Thanks for the tips, Vin Man.  I'm already getting some more ideas as to how to attack this little beast.

Well, the booth is together and painted (one long day)....I will mount the blower tomorrow.  I went and cut the flange on the blower so I could mount it flush against the booth and also made a couple of support mounts for the blower so it is supported and in the center of the booth.  Here is a pic of what I did...

Well, here are some pics of the booth painted with the blower mounted.  Test run worked great.

Special thanks to the VinMan for his ideas/tips/and advice.  I owe you a cold one!

You are very welcome. - But is it just me? I can't see your pics. I'm dieing to see how it came out!

That's funny....I can see them just fine.  I am posting them to my Yahoo Photos account.  Any idea what I'm doing wrong?

EDIT....I opened a PhotoBucket account.....they should show up now.

Hey, Cableguy --

While this may not be the greatest of help, here's what I did to keep from paying over 400 bucks for a tin box -- of which even the largest size available is way too small; for both the cost AND the utility.

I bought a Black and Decker base cabinet (any brand is fine, Rubbermaid, etc.) made from polyvinyl -- it has two doors that make a good seal when closed and includes an adjustable shelf, too, which comes in handy -- a dryer vent kit, and a ceiling exhaust fan, one in the mid-price range, about 25 bucks are the other two things needed.  Cut a hole in top of the base cabinet, mounted the fan, hooked the vent kit up, and vented it out one of my hobby room windows -- a set-up exactly like venting a clothes dryer.  The polyvinyl cabinet is a snap to clean, as any overspray which doesn't permanently change the color inside the booth is easily vaccuumed right out with a portable shop-vac using a brush attachment.  The exhaust fan is cleaned the same way.   The booth is very lightweight and three times the size of a "real" spray booth.  Took about 2 or 3 hours to build -- my first time attempting anything like that -- I've made 2 others for modeling friends, each in less than an hout.  Total cost:  $65.00.

 Placing the exhaust set-up in the center of the cabinet's "ceiling" has worked out great for me -- I get a nice, even pull on the entire inside, no matter at what angle or how much I'm spraying -- plus, I have the option of leaving one of the doors closed, for even better removal suction.  

Hope this might be of some help, or at least spark a few more ideas --

What a great idea! I'm kicking myself for not thinking of that—so much time and effort that would have been saved…

A word of caution about polyvinyl and other, similar materials: many (polyvinyl in particular) are vulnerable to degradation from prolonged exposure to ultraviolet, so you may not want to actually mount it in or near a window.
