Passive Automatic Vent Shaft Systems
FloodBreak engineers flood protection solutions for above grade and below grade vent shaft openings. These vent flood gates are designed for minimal airflow disruption and safely deploy without human intervention or power.
Designed for a long life and field tested in harsh conditions, these vent flood gates are custom sized to fit any vent opening.
How Do They Work?
When flood water enters the vent shaft, the panels “float up” to seal off the opening. The gate’s wiper walls block any water from going around the flood panel. When the flood event is over and the water has receded, the gates return to their dormant position.
