Positive-pressure air outlet

When a fire occurs, the internal electric actuators will open the ventilation outlets. At the same time, heat and smoke detectors or manual fire alarms will be activated. The positive-pressure fan on the rooftop will automatically start up, pressurizing the air supply shafts. Through the positive-pressure air vents in the stairwell’s antechamber, fresh air will continuously be supplied to the antechamber, maintaining positive pressure within the space and preventing smoke from spreading into this area, thus providing a safe escape route for occupants.

Product Description

In the event of a fire, the electric actuators inside will open the ventilation outlets. At the same time, heat and smoke detectors or manual fire alarms will be activated, causing the positive-pressure fan on the roof to automatically start up and pressurize the air supply shafts. The antechamber of the stairwell will receive a continuous supply of fresh air through positive-pressure vents, maintaining a positive pressure within the antechamber and preventing smoke from spreading into this area, thus providing a safe escape route for occupants. Once the temperature exceeds 280°C—beyond which human survival becomes impossible—the internal fuse will melt, automatically closing the ventilation outlets and effectively containing the spread of the fire.
