Gravity Louver
The self-closing louvered air vent is specifically designed for automatic exhaust in positively pressurized air-conditioned rooms. Normally, the louvers remain closed under their own weight, sealing off the air duct and preventing any exchange of air between indoors and outdoors. When indoor pressure exceeds outdoor pressure, airflow pushes the louvers open, allowing excess air to escape. Conversely, if outdoor pressure becomes higher than indoor pressure, the louvers automatically close again, effectively blocking backflow and ensuring one-way ventilation. Additionally, the vents can be customized with personalized color coatings.
