Introduction

Semi-rigid aluminum ducts are essential components in various building and industrial systems. Known for their flexibility and durability, these ducts provide efficient air flow channels. Typically composed of aluminum, they are favored for their lightweight properties and thermal conductivity.

Applications of Semi-Rigid Aluminum Ducts

1. Heating, Ventilation, and Air Conditioning (HVAC)

In HVAC systems, semi-rigid aluminum ducts are prevalent due to their ability to handle temperatures ranging from -30°C to 250°C. Their flexibility allows for easy installation in tight spaces.

2. Dryer Venting

These ducts are commonly used in dryer venting systems owing to their ability to withstand high temperatures and resist flammability. Standard diameters like 4 inches are frequently used in U.S. residential and commercial buildings.

3. Industrial Applications

In industrial settings, these ducts are employed for exhaust systems and air purification processes. Their durability makes them suitable for environments involving chemical exposure and high moisture levels.

Installation Considerations

Proper installation of semi-rigid aluminum ducts is crucial to ensure operational efficiency and safety:

• Length Constraints: The maximum recommended length for a dryer vent is 25 feet to maintain airflow efficiency.
• Bend Limitations: Minimize the number of bends to decrease the potential for air resistance. Each 90-degree turn reduces effective length by 5 feet.
• Sealing: Use appropriate duct tape to seal connections and prevent air leakage.
