Atlantis airbrush/compressor?

Well, I've contacted GP Hobby by mail, and they wrote, that this compressor has moisture trap and automatic pressure switch, that deactivates compressor at about 3.3 bar (approx 48-50PSI) and activates it again, once the pressure in tank falls below 2.2bar (approx 30-32PSI). Now I have a few qiestions here. First of all - isn't 50PSI a little to high for general use, what if I decide to do some fine spaying? Second, if there is no pressure regulator, pressure gradualy drops after deactivating a compressor, thus making spraying...well... uneven? I have read here on forum, that it is possible to do very fine airbrushing at about 10PSI. With compressor, that doesn't have regulator, I'll just have to wait while pressure drops to these 10PSI, I guess? Isn't it a monkey bussiness? OK, I'm pretty sure, that price is still very very good (c'mon - 180$ for compressor and double action gravity fed AB + about 20$ for S&H) and most entry level compressors don't have even this set of features. I just want to know if this pressure situation, I wrote above, is or isn't realy that much of an issue?

The pressure is probably going to be a problem unless you add a regulator. At that pressure you'll be blowing parts around. I seldom use more than 15 psi on mine.

That behavior is how all tank-fed compressors work. The pressure switch turns the pump motor on when pressure falls below a low set point and turns it off when the pressure reaches an upper set point. The tank simply acts as a reservoir fo the air. The only way to get it down to 10 psi without a regulator is to turn it off completely and then turn it back on, stop it at the desired pressure, turn it off, etc.

The regulator has an inlet side and an outlet side. The inlet high-pressure side does not care what the pressure is as long as it does not exceed the maximum rating. The adjuster adjusts the ontlet side so that it is at the desired pressure. As long as the pressure in the tank is at or above the setting on the regulator, that is the pressure that will be seen at the outlet side.

If it uses standard connections it would be a simple matter to add a regulator. I don't know how it is in Lithuania but here they are not at all difficult to find. Large hardware stores have them for about $20
