HornBlaster's 20 Gallon 7 Port Air Tank is the biggest air tank they carry and was made for serious mobile pneumatic uses. As with the other air tanks, the 20-Gallon Air Compressor Tank is built for high-flow applications, making it perfect for huge train horns, beastly air suspension systems and it gives you plenty of air to run air tools. To prevent bottlenecking issues, this tank features 7 high-flow ports: five 1/2" ports, one 3/4" port, and one 1/4" port.
Proudly made in the USA with the highest level of quality control and meets SAE J10 & FMVSS 121 specifications. Then finished with a semi-gloss black powder coat and then interior coated with a rust inhibitor, this tank is built to resist corrosion.
As an important safety precaution, a Safety Blow-off Valve should be installed with any air system. A Safety Blow-off Valve is designed to keep the system from over-pressurizing and to prevent damage to other components. It is suggested to use a Safety Blow-off 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 Blow-off and 120 PSI systems require a 150 PSI Safety Blow-off.
