Compressor for airbrush and castingpressure pot

[Delaney]

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, 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

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.

Nice tutorials - thanks for the links.

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
