Aluminum foil ducts are designed for air ventilation and can be used in different applications as follows: 1. Ventilation system, 2. Extraction of solvents, 3. Extraction of corrosive gas and fumes 4. Low pressure application, 5. Transferring hot and cold air for air conditioning 6. Vehicle construction, 7. Engine construction, 8. Exhaust fumes extraction 9. Generally used for smoke and dust exhausted. 10. Bathroom for air exhausting.

Knowledge of Aluminum Foil Flexible Duct

Flexible duct (also known as flex) is made with strong 3-ply aluminum foil laminate to resist puncture and tears. One continuous and corrosion resistant helix wire is placed in the duct wall for structural support. They have a variety of configurations. In the United States, the insulation is usually glass wool, but other markets such as Australia, use either polyester fibre or glass wool for thermal insulation. A protective layer surrounds the insulation, and is usually composed of polyethylene or metalized PET.

Flexible duct is very convenient for attaching supply air outlets to the rigid ductwork. However, the pressure loss is higher than that of most other types of ducts. Kinks in flexible ducting must be avoided. Some flexible duct markets prefer to avoid using flexible duct on the return air portions of HVAC system, however flexible duct can tolerate moderate negative pressures.
