Hydro1® Pedestrian Flood Door
The Flood Door That Sets the Standard
The Hydro1® Pedestrian Flood Door from PS Flood Barriers® redefines the term “multifunctional,” serving as both a passive flood-protection barrier and a normal-use pedestrian/egress door. The Hydro1 is engineered to be one of the best flood doors available, featuring the lowest leakage rate in the industry and requires no human intervention to deploy. Thousands of customers have trusted Hydro1 flood doors to protect hospitals, infrastructure, commercial facilities, transportation systems and mission-critical buildings around the world.
The Hydro1 is a purpose-built flood door, not to be confused with repurposed hollow metal doors that fail to meet flood codes (and feature gaskets on walking surfaces). The Hydro1 Pedestrian Flood Door is 100% customizable in single or paired configurations.
Our custom-built Hydro1 doors have been independent-party witness tested to 3′, 8′, 20′ and 30′ water protection heights with 50% less leakage than the ANSI/FM Approvals 2510-2020 4.3.3 standard (hardware included). In addition, FM Approvals has certified the Hydro1 Pedestrian Flood Door to withstand 8 feet of water and the new Hydro1-XFL to withstand an incredible 30 feet of water pressure. Not only did the Hydro1 and Hydro1-XFL pass, their leakage performance tested far below the maximum leakage rates allowed by FM Approvals standards. Based on this unmatched performance, we confidently recommend the Hydro1® as your best option.

*Water protection height is dependent not only on the door itself, but also on the supporting wall structure and overall load conditions. Performance values may vary based on the specific application and installation conditions.
**Fire latch is used on non-fire doors.
***FM XFL requires a face over lap frame.
