Product Summary:
The ventilation louver with gravity blades is designed for external ventilation, functioning as an exhaust diffuser. The four blades that form the gravity blade prevent reverse airflow, that is, movement opposite to the desired direction. This protects indoor spaces from external pollutants. An additional feature of the blade is the reduction of heat loss when the ventilation louver is installed externally.
