Passive Vent Flood Protection

FloodBreak designs flood protection solutions for building vents, whether above or below grade, and ground-level vent shaft openings. These dry floodproofing devices automatically prevent floodwater from inundating customer assets during a flood event but are designed to allow the free flow of air during dry times with minimal airflow disruption. 

The units utilize the same proven FloodBreak passive automatic technology as our standard flood barriers and deploy without human intervention or power.

A Permanent, Customizable Flood Solution

Designed for long service life with minimal maintenance and field-tested in harsh, real-world conditions, these vent flood gates can be custom-sized to fit virtually any vent opening and can be designed to be inboard duct work, inside vent shafts or face-mounted to buildings.

Floodproofing Wall Vents: The FloodBreak VSL

The FloodBreak Louvered Vent Panel system (FB-VSL) is a passive automatic flood mitigation device that provides 24/7 protection with minimal airflow disruption for vulnerable fan plants, vents, ducts and window openings, whether above or below grade.

Like all FloodBreak systems, the VSL deploys automatically without human intervention or power to prevent floodwater intrusion. The seals and mechanisms utilize the same materials and technology that have been in service and field-tested for over a decade, including real-world deployments and long-term exposure in a variety of field conditions.

Floodproofing Ground Vents: The FloodBreak VSS

Initially designed to protect MTA subway vent shafts from flash flooding, the FloodBreak Vent Shaft System (VSS) is an underground vent protection system that is passively activated like all FloodBreak solutions.

The vents will remain in the open position to allow the free-flow of air to the spaces below until floodwater starts to pour into the unit and float up the buoyant vent panels.
