The dual fill panel is constructed of stainless steel, high quality fittings and custom workmanship. The panel is made for fields or shops that need the speed of having a dedicated fill hose for 3000 PSI and a second fill hose for 4500 PSI. There are two gauges; one reads the regulated pressure and the other reads the bank pressure for filling 4500 PSI fills. The dual panel includes a pressure regulator mounted on the fill station that controls one or both sides. A toggle actuated fill valve relieves the line pressure when released, and rubber weights on the fill hose to prevent the hoses from whipping if pressurized.
