Yes, it is generally okay to leave air in your HPA (High Pressure Air) tank when not in use. In fact, it is recommended to store the tank with some pressure (usually around 500-1000 PSI) to help keep the seals tight and prevent moisture from entering. However, avoid storing it fully pressurized for long periods, as this can stress the tank.
