This is my new "dirty" corner, for painting and airbrushing. At the other end, to the right, is a clean bench for doing anything that doesn't involve paint. I'm left handed, so the brush to the left works well. The window points NW, so really good light. When spraying/airbrushing I use the face mask in the picture, but I'm thinking of some sort of extraction ventilation to go out of the window. Has anyone here made up an extraction system? I'm thinking of using a cooker hood fan, and making a wooden plate to go between the window and the frame. All comments, as ever, most welcome!
Notice: Go here to see a later post in this thread to see the final result: http://www.britmodeller.com/forums/index.php?/topic/234991809-finished-homemade-spray-booth-project-an-attempt/?p=2186396 I will have to do some detective work, but I thought I'd start by making this thread. I acquired this nice transparent storage case shown in the image below, and I have 6x used Noctua NF-P12 fans that fit nicely at the bottom of the case. I think I can make this work, but there is one problem that I am not sure how to deal with: Q: How do I power the six 12V (1watt) fans from the 230V power outlet? Presumably this is easy, but I have really no idea. Hopefully someone knowledgeable can chime in and state the obvious solution. That would be much appreciated. Putting on a hose and finishing the rear part behind the fans seems easy, so the power conversion problem is what seem difficult for me at this point. Ah, I forgot to point out the specifications for the NF-P12 fans: DC 12V (unsure if the 'direct current' part is important) Size: 120 x 120 x 25mm Rotational speed = approx 1300 rpm Airflow = 92,3 m3/h = 1,54m3/min = 54 cfm Static pressure = 1,68mm H2O Acoustic noise = ca 20 dB Input power = 1,08 W Input current = 0,09 A 1,54 x 6 = 9,24 m3/min = 324 cfm (unsure if it makes good sense multiplying these numbers by six) 9,24 seem to be double of what a popular spray booth seem to push out, though I am not certain the numbers for these two solutions are directly comparable. *unsure* Edit: Hm, I wonder if the six fans would be powerful enough. The popular spray booth on Amazon uses supposedly a 25W fan, which seem more powerful than my 6,5W setup. Not sure what to think about this. I have a 15cm wide table fan that uses 20W, that one doesn't really feel that powerful to me. Hm, I vaguely recall my compressor having 17L/min airflow, roughly 40-50psi constant pressure, unless I am totally mistaken. Maybe around 9L/min with 25 psi? Just guessing though.
