Hobby Spray Booth

[richhotrain]

Just a brief update on my spray booth project.

Back in September, I was trying to figure out how best to vent the fumes from the spray booth. In my last home, before I ever contemplated a spray booth, I dealt with moving basement air by mounting an exhaust fan on a sheet of plywood. The basement windows were removable, so I would remove the window and replace it with the plywood holding the exhaust fan. Here is a photo.

To vent fumes from my spray booth, I bought an ACINFINITY Raxial S6 Inline 6" Booster Duct Fan. Here is a photo.

I had planned to mount the venting assembly on a piece of plywood, much like what I had done in my prior home. But my wife convinced me to save time and expense and mount the old exhaust fan into the basement window and tie the new assembly to it. So I did. Here is a photo of my hybrid setup.

It looks a bit strange, but it sure works well. And, the wife is happy. No fumes.

Curiosity question.  Does the filter you are using have that x pattern support structure on both sides, or just on the side in your picture?

I use a 3M filter that has a support structure similar to what you show, also on the visible side.  And that would be correct using the air flow arrow as a reference.

However, this doesn't make much sense to me because the filter bows in toward the fan as it gets dirtier.  So I reverse the installation.  I did call 3M about this and the rep said that their engineers said it should work as designed, but I disagree.

Anyone else have an opinion?

The X-pattern is on both sides of the filter. An arrow on the top of the filter shows the intended direction of air flow.

Hi Rich,

I don't think it looks strange at all! I think it looks great!

If I can make a suggestion, get yourself a light that will fit inside the top of the booth to eliminate the shadows and give you a clear view of how well the paint is covering.

Cheers!!

Dave, you are right about the lighting.

I need an overhead light inside the spray booth.

Thanks, much better design than the ones I found.

What is the brand, and did you get it at one of the big box stores?

I would agree with what you're saying. Maybe somebody should tell MLW?

I'm not sure I would use one of the 'high efficiency' filters, though. Seems to me it would get plugged rather quickly especially if you're shooting something heavy bodied such as primers. When I used a paint booth I made my own filters and I had a 50 foot roll of 'Aquarium Filter' media. It was a little denser than the old style furnace filters used to be but not as dense as the newer HVAC-type filters that seem prevalent today.

Something similar to this:  https://a.co/d/5Scz97Y

I needed a somewhat odd size so I ordered on line from a vendor called Filterbuy. The stated size is 14x18x1, and the actual size is 13.5x17.5x0.75. The filter is graded MERV-8. The air flow output side has a thin wire reinforcement pattern, but not the air flow input side (the visible side in the spray booth).

Got it. Thank you.
