The certification process conducted by FM Approvals—an independent organization recognized for rigorous safety standards—confirmed that these pedestrian doors maintain exceptional leakage performance. While the standard Hydro1 model is rated for 8 feet of water, the newly introduced Hydro1-XFL variant offers protection against 30-foot depths. According to Mark Haaland, sales and marketing director at PS Industries, this validation provides building owners with a reliable solution that combines everyday usability with passive, human-intervention-free security.

Beyond FM certification, select configurations have earned Florida Product Approval #39631, confirming their suitability for the High Velocity Hurricane Zone in Miami-Dade and Broward counties. Independent testing revealed that these doors consistently perform 50% better than the ANSI/FM Approvals 2510-2020 standard regarding leakage rates. Currently, these systems are deployed across critical infrastructure sectors, including hospitals and transportation hubs, to ensure continuous protection during flood events.
