Ventilation duct water intrusion prevention system (VSS)
Simply install the unit on the ventilation duct that connects to the underground, and it will automatically open and close the gate using the power of water, preventing flooding in the underground space.
VSS from FloodBreak, a company for which we are the agent. It utilizes the power of water during floods to automatically close the panels within the unit. There are no mechanical or electrical mechanisms, so no personnel or power are needed to close the gate. This is a unique and groundbreaking system that avoids human risk during installation and automatically deploys even when lifelines are lost. Once the water recedes, it automatically returns to the open position, ensuring that ventilation functions are not compromised during normal conditions.
