Deahan Korean Fabric Flexible Air Duct

Deahan Korean flexible fabric ducts are widely used in HVAC and ventilation systems for commercial and industrial projects. Made from durable polyester and PVC fabric reinforced with a steel wire helix, Deahan ducts ensure flexibility, strength, and heat resistance for long-term performance.

There are two main types:

1. Non-Insulated Flexible Duct

Lightweight and easy to install, ideal for air supply, return, and exhaust systems. It resists tearing, corrosion, and moisture, operating in temperatures from -20°C to +80°C.

2. Insulated Flexible Duct

Constructed with three layers — outer PVC fabric, fiberglass insulation, and inner aluminum foil — this type minimizes energy loss and condensation while reducing noise and vibration. It works within -20°C to +140°C, perfect for central HVAC and air conditioning systems.

Advantages

• 100% imported from Korea – high-quality Deahan brand.

• Certified fire-retardant and durable materials.

• Fast installation, lightweight structure.

• Long lifespan and stable airflow performance.

Case Example

At Lotte Center Hanoi, insulated Deahan ducts were used in the central HVAC system. Results after two years showed:

• 15% improvement in cooling efficiency.

• No condensation or air leakage.

• Noticeably quieter operation.
