Our 20 Gallon 7 Port Air Tank is made in the USA with the highest level of quality control and meets SAE J10 & FMVSS 121 specifications.

As an important safety precaution,  a Safety Blowoff Valve should be installed with any air system. A Safety Blowoff Valve is designed to keep the system from over-pressurizing and to prevent damage to other components. It is suggested to use a Safety Blowoff Valve with a PSI rating between 25-35 PSI higher than the maximum pressure of the pressure switch.

For example, 150 PSI systems require a 175 PSI Safety Blowoff and 120 PSI systems require a 150 PSI Safety Blowoff.
