Brief Introduction
The aluminum gravity louver air outlet features automatic exhaust from the positive pressure zone to the negative pressure zone, as well as a one-way non-return function.
When there is no pressure difference between indoor and outdoor, the louver blades hang down naturally by their own weight, blocking air flow exchange between the two spaces. When the indoor pressure is higher than the outdoor pressure, air is exhausted outdoors. When the indoor pressure is lower than the outdoor pressure, outside air cannot flow into the room. Therefore, the aluminum gravity louver air outlet shall be installed in a specified direction.
