Staircase And Lift Pressurization System

SK Ventilio engineers staircase and lift pressurization systems that maintain positive pressure differentials in escape staircases and lift shafts, preventing smoke from penetrating these critical evacuation zones during a fire. Our designs are precisely calculated to meet door-opening force limits while maintaining the pressure differential required by fire safety standards.

Whether for a high-rise residential tower, commercial office block, or hospital, our pressurization systems are designed to reliably activate on fire alarm trigger — giving occupants and emergency responders a safe, smoke-free passage throughout the evacuation process.
