The Original PD-522 Fire Rated Flood Door from PS Flood Barriers™ – designed and tested to meet FM standards – is a normal-use swing door, specifically engineered for interior and exterior openings requiring watertight flood protection and a 90-minute fire rating. Always in place, this dual-defense door provides unmatched flood and fire protection while allowing pedestrian access to your facility.

This passive flood protection door provides powerful flood security with water-protection heights up to 11 feet. It’s designed for hydrostatic, hydrodynamic and impact-loading requirements. Available in mild steel or stainless steel construction.

While our Original Fire Rated Flood Door is ideal for situations that require a FM rated flood door, PS Flood Barriers™ has recently introduced a purpose-built Hydro1™ 90 Min. Fire Rated Flood Door that features the lowest leakage rate in the industry. The new Hydro1 doors have been third-party witness tested to 3′ and 20′ water protection heights with 50% less leakage then the ANSI/FM 2510 Section 4.3.3 standard (hardware included). The Hydro1 doors have not yet been FM rated, but are ideal for all other situations where a FM door is not required.
