Does adjusting the regulator allow some of the pressure to bleed out and thus leave you with the amount of pressure needed for airbrush use?
Reason for my question is I’m pondering buying a pressure tank at the hardware store. It is 10 gallons and compessible up to 130 psi. If a regulator contantly bleeds pressure then the tank may not last long if I take too long painting.
The detailed explanation is semi-complicated, particularly without pictures, however you don’t have to worry that you’ll be airbrushing at 15PSI and simultaneously venting at 115 PSI, thus quickly emptying your tank.
ABARNE’s right, the preasure will only bleed off when you have the trigger depressed on your ab, so you shouldn’t be in much danger of bleeding the tank dry.
doesnt matter how it does it; its magic. 20psi comes out or whatever its set at; and thats all. nothing more; it maintains 20psi untill the tank pressure drops under 20psi. itll last longer than a can of compressed air; and its free to refill and about 20-25$; thatll make up for itself in like 8 fills or less.
To put it simply, the pressure regulator keeps the air from comming out too fast. It blocks the air passage so only the desired PSI will come out
