Vacuum Pressure Water Supply Units, also known as Pressure Boosting Systems, are primarily used for secondary pressure boosting in high-rise buildings with city water networks. Advantages: Energy-saving – boosts the pressure of the existing network, Sanitary – water does not stagnate in the vacuum tank, preventing spoilage, Compact – occupies one-tenth of the space of traditional water supply systems, Fully Automatic – equipped with variable frequency, timing, and quantitative control for unattended operation. Technical Parameters: Flow Range: 3l/s ~ 300l/s, Head Range: 30m ~ 240m
