Introduction

Flexible ducts are a critical component in modern airflow and ventilation systems. These ducts enable efficient transportation of air in various environments, including residential, commercial, and industrial settings. Available in materials like plastic and metal, flexible ducts offer adaptability and ease of installation compared to rigid counterparts.

Applications of Flexible Ducts

1. HVAC Systems

One primary use of flexible ducts is in Heating, Ventilation, and Air Conditioning (HVAC) systems. These ducts allow the distribution of heated or cooled air throughout buildings. Typically, flexible ducts in HVAC systems have a diameter ranging from 4 to 18 inches and can handle airflow velocities of up to 2,500 feet per minute.

2. Industrial Ventilation

In industrial settings, flexible ducts facilitate the removal of hazardous fumes and provide fresh air to workspaces. Designed to withstand harsh environments, these ducts can operate efficiently in temperatures ranging from -20°F to 250°F, ensuring safe and effective ventilation.

3. Exhaust Systems

Flexible ducts are also used in exhaust systems to carry out smoke, fumes, and other emissions from various industrial processes. These ducts are engineered to handle pressures up to 10 inches of water gauge (WG) and are often reinforced with wire helixes to maintain structural integrity under negative pressures.

Advantages of Flexible Ducts

• Easy installation due to lightweight and flexible nature
• Cost-effective compared to rigid duct systems
• Minimal noise production due to flexible materials reducing vibrations
• Available in a variety of sizes and materials to suit different applications
• Adaptable to existing infrastructure, providing solutions for complex duct layouts
