Variable speed custom paint booth built in 2 full days

Recommended Posts

After taking inspiration from someone else's paint booth, I built my own. The (4) 12VDC fan plate is from an old paging transmitter. (Remember pagers?) I bought a variable DC power supply so that I can vary the airflow as needed. I wanted it wide so I have plenty of room for my part on a stick and a full size rattle can. So I chose a 16x25x1 air filter as my starting point. I built a frame that allows easy changing of filters. My base plate is 1/4 high density fiberboard. I mounted the fans and soldered in a jack for the DC input. I do not have the privilege of leaving it set up so I had to make it portable. It comes apart so I can store it in the garage. I have read about how restrictive 4" flexible ducting is so I made a very low restriction plenum. I used 1x2s and a heavy duty double thick cardboard moving box. I made the window insert from the same materials. For lighting I used an old 18" fluorescent under cabinet light that I had in my old shop. I skinned the outside with some leftover pegboard and I skinned the inside with corrugated plastic sheeting. I work in the HVAC field so I can get good air filters for less than $4 instead if $16 at Home Depot. Now my Freightliner build doesn't have to wait for Spring to continue on.

Nice.  I have a dedicated table to airbrush/spray and really need to build something to vent the fumes outside.  I have an old range hood that I am thinking of using.  It might or might not work.

During my research, I have seen others use one successfully.

Nice booth!

Unfortunately I do not have a window in or near my hobby room. So I've been spraying in the garage.

However I do have a bathroom attached to my hobby room, and have contemplated running a duct to the bathroom exhaust fan. I figure a good length of flexi pipe should do the trick... but then have to figure out how to clamp the hose in place.

Oh well, another project for another life.
