If you've read any of my other posts, you'll see I like giving out information. This is because there's really precious little of feedback on these tools and how they work. However, they can make ALL the difference in your enjoyment of the hobby.
Well, here's some other info- with pics! A bit about my spray system. I have been very pleased overall with my set up. I wanted something that I could have in the house, so I didn't have to freeze in the garage, nor be in a dank, dusty or dark basement (all of which I have done.). So I came up with the hobby amoire- From home depot, I think. Got another shelf and split it into three sections. Its a mess right now, but works pretty well. I was trying to make the center section my main work area, but it was too cramped.
Here's some shots closed and open. Wife hates the crap on top and on the sides, but you can't see most of it. I'm planning on putting most of it in the closet.
Here's a shot of the paasche booth- fits well in the top. Poked a hole in the back, so the motor could stick out and I could vent it. Right now the filter is not in it, I think because I was spraying and there was a lot of overspray. It vents well, but this decreases with the filters.
Here's how I vent: I use some flexible venting hose. Cut a piece of masonite and put the vent connector in it. it is slightly larger than the frame of the window, so I flex it and it pops into the frame, then I put the window down, and it seals 'o.k.'
You don't get a lot of backdraft or leakage, I think due to the flow without too much pressure- easier for everything to go towards the path of least resistance -> outside, than leak, etc. Don't get a lot of fumes.
Hope this helped.
