Overpressure by means of air supply causes inside the escape route such pressure that, at the same time,
it will prevent the entry of smoke coming from the fire combustion. This is achieved by generating a pressure
greater than the outside.
The Casals Ventilación staircase overpressure system consists of a control panel (KIT-PE) and an air supply
unit (any fan for air supply) that will provide the stairs or the escape route with enough pressure. It is available
for three-phase and single-phase equipment.
