The Nuaire NU-1550 TankGuard Automatic Tank Switch is easy to install connecting tank tubes by hose barb on the back of unit. The tank switch automatically changes to an alternate CO2 or N2 gas tank when the primary tank is empty.
The TankGuard automatic tank switch has been designed to provide reliable service to perform the critical backup gas (i.e. CO2, N2) tank switch for a tissue cell culture incubator. The TankGuard tank switch continuously monitors and indicates the selected source gas tank and the status of the non-selected or secondary source gas tank. If the selected source gas tank pressure falls below 8 PSI, the selected source internal pressure switch will detect the low pressure and automatically change sources.
