Staircase Pressurization System Explained | Fire & Smoke Control in HighRise Buildings(3D Animation)

In this video, we explain how a staircase pressurization system protects people from smoke during a fire. Using simple animation, you will understand how pressurized air prevents smoke entry into staircases. We also cover door opening force, pressure relief damper, and VFD-based fan control. This system is mandatory in high-rise buildings for safe evacuation.
