Title: Compressor for airbrush and castingpressure pot
Post by: Delaney on August 07, 2012, 11:04:24 AM
Can anyone recommend a compressor for both airbrushing and pumping a painters pressure pot up to 40psi for resin casting?

No idea, but according to this tutorial (http://www.militarymodelling.com/news/article/resin-casting-for-beginners-part-1/5460/), even a fridge compressor suffices.
oil-lubricated compressors tend to last longer than the oilless ones. Normaly you can find a 1,5 HP model with a small tank for around €100.
As you only need to build up pressure, flow isn't important (if you intend to use powertools however...)

I also found this on the web : http://www.donjarrs-place.com/07-how-to-vacpot (http://www.donjarrs-place.com/07-how-to-vacpot)

Try to contact Zafarelli on this forum, he has extensive experience in casting resin and using a compressor in order to evacuate a pressure chamber.   :)

I'd go for a silent airbrush compressor. If you have the experience to convert them, fridge compressors do nicely for airbrushing as well. The large compressor I use for my pressure pots is so loud I tend to use earmuffs when casting, but the airbrush compressor is much too slow to fill the pressure pots in time.

A word of caution, though: stay away from those glass containers in the tutorial Zizi quoted. 40 psi is not a pressure you want to joke around with. Neither do you want to be in the vicinity of an exploding cucumber glass.

That sounds like it was learnt from experience.

As zaffarelli said, a slow and silent compressor could not be great for resin casting, but i would be interested (even though it might be a little OT) in a nice compressor for airbrush.

Considering that i live in a flat, with some very angry neighbours below, i can't even consider to use a noisy one. the void pump should be a great improvement to me, but probably i've to change house before... XD
