ABSTRACT:
A method and apparatus for supplying and maintaining an aseptic gas atmosphere in a storage tank for spoilable contents such as foodstuffs and the like. The aseptic gas is supplied from a container under pressure and is maintained at the desired pressure in the storage tank by pressure-reducing valves in a supply line or conduit having a microbiological filter and pressure-maintaining valve that functions in place of a relief valve in the supply line. It responds to excess pressure in the storage tank and relieves the excess pressure through the same supply line through which gas is supplied without need of a relief valve on the storage tank.
