Passive Automatic Flood Protection for Vents

FloodBreak designs flood protection solutions for building vents, whether above or below grade, and ground-level vent shaft openings. These dry floodproofing devices 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.

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.

    Louvered Vent Panel System (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. Fully passive automatic, 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.

    Innovative Engineering Design

    The passive vent panel system is a series of buoyant louvered panels enclosed within an aluminum box & shelf structure providing protection to the designed flood elevation.

    As the floodwater rises, the panels “float” into position, lifted by the water. Wiper seals stop the water from going around the panel edges. Only panels affected by the flood are raised leaving the remaining louvers open in minor flood events. Once the floodwaters recede, the panels return to the rest position allowing airflow to resume.

      Custom Sized To Fit Any Vulnerable Vent Opening

      The VSL system can be designed with a single panel or a series of panels depending on the opening and can be installed either partially or fully inside an existing vent opening. Or it can be surface mounted to the building wall depending on available space and airflow requirements. It can be covered with wire mesh or be installed behind existing gratings.
