The External Auto Switchover System by AquaSafe is an advanced, vacuum-operated gas chlorination solution engineered to automatically switch chlorine feed from an empty cylinder to a full one—ensuring uninterrupted, 24/7 disinfection without manual intervention. This high-performance system features two independent vacuum regulators mounted directly on chlorine cylinders, manual flow rate control, and a water-powered ejector with built-in backflow prevention. Designed for reliability, safety, and operational continuity, it transforms traditional chlorination setups into modern, automated systems—ideal for municipal and industrial water treatment applications.
