Self-hanging louvered air vent

Self-closing louvered air vents are used for automatic exhaust in air-conditioned rooms with positive pressure. Normally, the louvers hang naturally under their own weight, preventing air exchange between indoors and outdoors. When the indoor air pressure is higher than the outdoor air pressure, the airflow pushes the louvers open to exhaust air outwards. Conversely, when the indoor air pressure is lower than the outdoor air pressure, the airflow cannot flow back into the room; this vent has a one-way check valve function. The aluminum alloy surface is anodized, and electrostatic powder coating can also be applied upon request.
