The write up on airflow requirements is a major factor in my decision to buy a spray booth as purchasing a fan with sufficient CFM would have been half or more of the cost of an inexpensive commercial spray booth.
Apologies to those of you who just saw my booth photos on another thread.
Yeah Dave, you were very helpful a few weeks ago on my project. Tip: Line the inside walls with aluminum foil and you’ll greatly enhance the lighting inside. Mine’s the Paasche galvanized steel booth so I keep the foil in place with a pack of cheap “Altoid” size magnets from Lowe’s. Use double sided tape or duct tape and you’ll do as well, and it keeps the booth lookin’ sharp. I have a small 5 1/2" dia clamp-on work light attached to the sidewall with a 40 watt bulb. Six bucks at the same place and it floods the place with light.
