Paint shop design

Paint shop design

Paint shop design

What are the requirements to design an enclosed paint shop for aviation facilities that also require comfort cooling. The size of the building is 23m x 12m x 7m high.

RE: Paint shop design

Is this going to be a full time paint shop or is this a general aviation hanger in which aircraft are painted from time to time.
 Also what type of paint is going to be sprayed?
The temperature and humidity requirements for spraying cellulose paint (Dope) are much more stringent than enamel base paints.

RE: Paint shop design

It is a dedicated paint shop building where parts or portion of aircrafts will be painted whenever required. The requirement is to have a temperature suitable for people working inside it. It must not exceed more than 85F.

RE: Paint shop design

If you are only spraying components such as wings or fuselages and not an assembled aircraft, then I think you would be best off, with a side draft or down draft dedicated spray booth, rather than painting in an open shop. If this is the case you will need a  velocity of 60 to 100 feet per minute (18m to 30m ) at the face of the booth depending on the quantity of paint you are spraying. The size and velocity of the ducting will be dependent on the size of booth you choose.
 I do not know the ambient air temperature or the relative humidity where you are located . Most solvent base paint systems do not like  temperatures over 75degrees F and relative humidity's over 40%. Also any air you remove must be made up with outside air, If this air is outside your temperature requirements it will have to be heated or cooled.
I am adding a link to an old set of OSHA requirements for spray booths, which may, or may not, apply depending on where in the world you are, but will give you some useful guidelines. http://www.uic.edu/sph/glakes/harts1/HARTS_library/spraying.txt

  It should also be noted that what may satisfy OSHA will horrify the environment agency. So you will have to get some local expertise to cover your pollution rules.
