What is the optimal position for a grease duct to improve ventilation?

The optimal position for a grease duct to improve ventilation is vertical. When grease ducts are installed vertically, they facilitate better airflow and reduce the chances of grease accumulation within the ductwork. The vertical design helps to create natural convection, allowing heat and smoke to rise and exit through the exhaust system more efficiently. This upward movement enhances the overall effectiveness of the ventilation system, especially in kitchen areas where grease-laden vapors are produced. In addition, a vertical configuration helps in minimizing the risk of fire hazards associated with grease buildup, as it allows for easier maintenance and cleaning of the system.

While horizontal ducts can be used, they often require careful planning to ensure proper airflow and may need additional features, such as adequate slopes for draining grease. Therefore, the vertical positioning is generally preferred for optimal performance and safety in grease duct applications.
