Flexible Aluminum Foil Duct Series | HVAC Ventilation & PVC Composite Hose
High-Performance Aluminum Ducting Solutions for Versatile HVAC Systems
Our premium aluminum foil ventilation duct series offers highly adaptable, reliable airflow solutions tailored for residential, commercial, and industrial HVAC networks. Manufactured with an advanced helically shaped internal crimped galvanized steel strip lock system, these ducts ensure a 100% airtight and leak-proof seal capable of handling both low and high-velocity air distribution.
To meet diverse mechanical layouts and engineering safety codes, our ducting is available in four specialized material structures, ensuring excellent strength, fire resistance, and superior bending performance to easily overcome tight ceiling obstructions.
Four Specialized Product Variants
1. Standard Aluminum Foil Duct

- Best For: Environments needing external moisture protection, UV defense, and extra chemical resilience.
4. Aluminum Foil Fiberglass Duct
- Structure: Advanced fusion of aluminum foil Mylar and premium anti-burning fiberglass cloth fabric.
- Thermal Range: -30°C up to +200°C (Highest thermal tier).
- Best For: Demanding high-temperature hot air extraction, commercial kitchens, and strict fire-rated ventilation layouts.
Specifications & Technical Parameters
Product Matrix & Sizing Chart
Standard material thickness sits at a balanced 0.5mm, utilizing internal steel wire gauges from 0.8mm to 2.0mm to preserve flexible elasticity without sagging. Review the complete classification parameters below:
| Duct Type / Variant | Available Diameters (ID) | Standard Thickness | Temperature Range | Internal Steel Wire | Standard Length |
|---|---|---|---|---|---|
| Standard Foil | Φ50mm --- Φ400mm | 0.5mm | -30°C to +120°C | 0.8mm -- 2.0mm | 10 Meters |
| Double-Layer | Φ50mm --- Φ400mm | 0.5mm | -30°C to +120°C | 0.8mm -- 2.0mm | 10 Meters |
| PVC Composite | Φ50mm --- Φ400mm | 0.5mm | -30°C to +120°C | 0.8mm -- 2.0mm | 10 Meters |
| Fiberglass Foil | Φ50mm --- Φ400mm | 0.5mm | -30°C to +200°C | 0.8mm -- 2.0mm | 10 Meters |
Note: Multiple sizes are fully supported across all four models. Custom cut single lengths (such as 7.5 meters) are entirely customizable based on project blueprint configurations.
OEM Customization & Logistic Efficiency
H3: Custom Lengths & Flexible Production Runs
- Minimum Order Quantity (MOQ): 10 pieces.
- Flexible Length Tuning: Our standard factory line yields 10 meters per single duct. However, we offer complete OEM support to deliver custom pre-cut iterations (e.g., 7.5 meters) to match modular engineering requirements perfectly.
H3: 10% Compression Freight Savings
To help international wholesale distributors minimize expensive shipping markups, this aluminum ducting series possesses outstanding compression elasticity. A full-length 10-meter duct can be safely compressed down to just 10% of its extended size for packaging. This slashes volumetric carton displacement, dropping ocean/air shipping and local warehouse storage expenses to a bare minimum.
Frequently Asked Questions (FAQ)
Q1: What are the differences in temperature ratings across this series?
A: Our Standard Single-Layer, Double-Layer, and PVC Aluminum Composite options handle continuous temperatures from -30°C up to +120°C. For higher thermal settings, our Aluminum Foil Fiberglass Duct utilizes specialized anti-burning glass cloth to safely withstand up to +200°C.
Q2: Can we place custom OEM orders for 7.5-meter runs or specific colors?
A: Absolutely. While 10 meters is our standard shelf layout, we can custom-cut the ducts to 7.5 meters or other specific lengths. For the PVC Composite variant, custom outer jacket color schemes can also be arranged to align with your machinery design.
Q3: Does the duct preserve its structural shape when bent sharply in ceilings?
A: Yes. Reinforced by an inner high-tensile spring steel wire helix (0.8mm to 2.0mm), our ducts avoid structural kinking or sagging when making sharp bends around tight false ceiling beams and joists, maintaining consistent airflow velocity.
Q4: How does the compression system affect overseas shipping costs?
A: Because these flexible ducts easily compress down to roughly 10% of their extended volume, we can package them tightly without transferring empty air spaces. This helps you fit substantially higher quantities into every ocean freight container, resulting in enormous savings on international transport.
