Flat Oval Ducts

Flat oval ducts are a type of ductwork used in HVAC systems. As the name implies, they have an oval-shaped cross-section that is flatter than traditional round ducts. These ducts are typically made of galvanized steel or aluminum.

Flat oval ducts offer several advantages:
1. Space Efficiency: They can be more space-efficient than round ducts, especially in areas with limited overhead clearance or tight spaces between floors.
2. Improved Airflow: Flat oval ducts offer better airflow characteristics compared to rectangular ducts, with reduced pressure drop and less turbulence.
3. Enhanced Noise Reduction: The shape of flat oval ducts helps reduce noise transmission, making them suitable for noise-sensitive environments.
4. Ease of Installation: Flat oval ducts can be easier to install than round ducts in certain applications, especially when navigating around obstacles or fitting into confined spaces.
5. Aesthetic Appeal: They can provide a more aesthetically pleasing appearance compared to traditional rectangular ductwork, making them suitable for exposed installations.

Despite these advantages, flat oval ducts may also have some limitations, such as higher fabrication costs compared to rectangular ducts and potential challenges in sealing joints due to their shape. However, they are a popular choice in many HVAC applications, particularly where space constraints or airflow performance are important considerations.
