Hi,
I’m building a spray booth in a tall cabinet, and I can set the bottom of the booth at any height I choose. I would like to get this right the 1st time, so I don’t have to tear the cabinet apart to change the height of the bottom of the booth.
What is the height of the bottom of your spray booth from the floor? I should add that I’m 5’ 10".

You need to give a few more specifics like what are the dimensions of the booth, will yo be able to walk inside and close the door behind you? I would suggest making the bottom of the booth which I am assuming is some sort of shelf adjustable. so this way if you happen to be painting a taller structure let say you can just move the shelf down enough to accommodate it. Under normal circumstances you want it about 48" off the floor a comfortable work height but then again I have sprayed models sitting on a stool at a work bench without a booth. I have an overhead pick up with a hepa filter and some duct work leading out to a plywood panel that replaces a basement window. It uses an inline explosion proof motor I had laying around. The whole thing didn’t cost me $25.00 to make. if your building a spray booth be warned you absolutely need to use explosion proof lighting and an explosion proof fan and the switches you use to turn them on should be mounted outside the booth. The type with the open face like you see in Micormark are ok as the fumes aren’t contained in a closed space. so they are more for containing your over spray.
In a closed space it doesn’t take a heck of a lot of fumes from spraying paint and one little arc form an electric motor or switch to cause a very BIG explosion.
Rule of thumb: the middle of the booth is where you hold the airbrush when spraying horizontally. This should allow you too spray down on a loco without handling it. Adjust from there . Alow for the height of a lazy susan and any holding device. Try it out with a cardboard box.
Bathroom fans work well and are economical. They fit the criteria because they are brushless by code in the US. Get one that moves about 90 cfm (cubic feet per minute) or better.
