Thank's, -- it's like I thought, as the airbrushes that was with it have a working preasure of 30 Lbs.sq.in. down to some 10 Lbs.sq.in. That translate into between 2.04 Atm. and 0.68 Atm. I guess most quality brushes will work with that.
It came with two airbrushes for very fine lines , but I guess I will just let it feed the brushes it allway's belonged. Also it's proberly easier to move than the Emda that is near 20 Kilo.
But not that it matter that much as my Emda been turned on since the day it was powered up and it will make some five atm if that's what I want. But I never worked with a membrame compressor, ---- just hope it is as silent as the Emda.
