Air Brush Paint Booth Takes Shape!
| || |
The basic structure of this paint booth project is a plywood box measuring 15" high x 18" wide x 30" deep. The top, bottom, and one side have been glued together. The other side will be screwed in place ensuring that all components can be accessed if needed in the future.
An important design feature is the angled center wall which separates the painting chamber from two ventilation chambers. This piece was cut late last night. It is great to see a design on paper come to life!
Using clamps we positioned the fourth side on to facilitate visualization of how the finished product will work. I am very comfortable that the painting chamber is sized appropriately. Once the middle wall was cut, we were able to locate the best position for it in the box to allow enough room for for the ventilation chambers to function while leaving adequate room in the painting chamber.
There are several possible configurations which would require the location of the filter access door to be relocated. At this point, not a big deal. The below slideshow displays various component configuration possibilities:
Actually the fan motor (NuTone Model 696N) is an enclosed shaded pole, thermally protected, 120vAC, 60 Hz, .9 amp. design. I believe that given the travel distance the paint vapors will travel from the airbrush to the fan, via a filter, the potential for ignition with this fan motor is minimal. The real test will come when the motor's power is tested in the enclosed chamber to see if it is strong enough to maintain proper airflow out of the painting chamber. My initial calculations indicate that it will work.
