150 lbs is the amount of pressure in the tank. When you connect a nail gun for instance you cannot nail everything at 150 lbs of pressure, it will blast through. The regulated pressure is at zero because you have the ability to regulate it by turn the know under or beside it to increase the output pressure to your desired amount. I was building a shelf last week and set my regulated to 80lbs with a brad and it blew through the panel and stuck in the floor. After you get to know your nail gun you will be able to regulate it between 60 and 80 depending on the type of wood. Panel - 50 lbs, Oak, 90 lbs, etc. Pleas remember to rate this solution high if it was helpful and explained it to your satisfaction.
