1. What is an Aluminium Foil Duct?

Aluminium foil duct is a lightweight, flexible, and fire-resistant tubing solution constructed from multi-layer aluminum foil reinforced with spiral steel wire. Designed for air ventilation, HVAC, and fume exhaust, these ducts combine excellent corrosion-resistance, heat tolerance, and structural flexibility. Widely implemented as aluminum foil duct hose or as a flexible aluminum foil duct variant, these systems optimize airflow while maintaining safety and installation ease.

6. Professional FAQ – Aluminium Foil Duct Technical FAQ

Q1: What is the core material in aluminum foil duct manufacturing?: A: Top-grade aluminium foil (usually series 8011, 1235, or 3003) is laminated with fire-resistant glass fiber fabric and reinforced using spiral steel wire (Q195/235).
Q2: How is the thickness of aluminium foil duct specified?: A: Standard wall thickness is 0.5mm, measured by micrometer across both foil layers and core fabric. This balance offers durability and flexibility.
Q3: What diameters are available for flexible aluminum foil duct?: A: Industry sizes range from 50mm up to 600mm inner diameter, with special custom sizes for OEM projects.
Q4: What fire resistance standards does aluminium foil duct meet?: A: Compliant with Class 0/1 (EN 13501-1, BS 476 Part 6/7), ensuring flame retardancy and minimal smoke development.
Q5: How to install an aluminum foil duct for best air-sealing?: A: Use specified stainless steel duct clamps at joints, maintain a smooth, untwisted route, and seal seams with UL-listed foil tape for maximum efficiency.
Q6: What are the typical static pressure and airflow capacities?: A: For a 150mm duct at 120Pa pressure, airflow reaches approximately 800–900 m³/h. Pressure resistance up to 2000Pa for industrial grades.
Q7: Is aluminum foil duct suitable for corrosive gas exhaust?: A: Yes, as aluminium is naturally corrosion-resistant; however, for highly corrosive gases, consider PVC/insulated duct variants or internal coating options.

7. Choosing & Ordering Aluminium Foil Ventilation Duct

Specify diameter and length (standard coils: 5m, 10m per piece).
Confirm wall thickness and steel wire gauge for your pressure and flexibility needs.
Identify application (HVAC, kitchen exhaust, cleanroom, etc.) to select correct fire-resistance and material class.
