What’s the Real Difference Between “Ventilation Duct” and
“Ducting Fabric”?
In tunnel and mining ventilation systems, many people are confused by two seemingly similar terms: Ventilation Duct and Ducting Fabric. Are they the same thing? Can the terms be used interchangeably?
The answer is: not exactly. While the names sound alike, they serve different roles in industrial applications. Let’s break it down.
Ventilation Duct vs. Ducting Fabric: More Than Just a Word Apart
- Ducting Fabric is a general term referring to the raw materials used to manufacture all kinds of ventilation ducts. Typically made from high-strength coated fabrics (such as PVC, polyester, or TPU), ducting fabric is a core material in any ventilation system.
- Ventilation Ducts (also known as tunnel ducts, mining ducts, or flexible air ducts) are the final products made from ducting fabric. These ducts are used to channel air through enclosed spaces like tunnels, subways, mines, or ships.
In simple terms:
Ducting fabric is the material; ventilation duct is the product.
Common Applications of Ducting Fabric
Ducting fabric is highly versatile and can be used to produce:
- Tunnel ventilation ducts
- Mining ventilation ducts
- Flame-retardant and anti-static ducts
- Marine-grade flexible air ducts
- Industrial ducting for general ventilation
Each application scenario has different requirements for ducting fabric—such as flame resistance, corrosion resistance, tensile strength, and flexibility.
Why the Quality of Ducting Fabric Matters
In tunnel or mining construction, proper airflow is critical. Poor-quality ducting fabric can lead to:
- High wind resistance and energy consumption
- Severe air leakage
- Easy tearing and short lifespan
- Poor airflow, causing safety risks underground
High-quality ventilation ducts are usually made from coated or laminated ducting fabric, offering strong sealing, low resistance, and good pressure tolerance. This ensures safe and efficient long-distance air delivery.
Two Common Types of Ventilation Ducts
Material selection is key when purchasing ventilation ducts. The most common types include:
1. Flexible Ducts (PVC, polyester, TPU)
- Lightweight and easy to install
- Optional flame-retardant and anti-static properties
- UV-resistant and suitable for semi-outdoor use
- Ideal for tunnels, mining sites, and temporary setups
2. Metal Ducts (Spiral or rigid steel)
- Very durable and long-lasting
- Suitable for fixed or permanent installations
- Less flexible and harder to redirect airflow
In most tunnel or mining projects, flexible ducts are more popular due to their portability, moderate cost, and low maintenance.
How to Choose a Reliable Ventilation Duct Manufacturer
The market offers a wide range of duct products, and quality can vary greatly. A reliable supplier should meet these standards:
- Material thickness and tensile strength are up to standard
- Airtight sealing and secure joint connections
- Strict quality control before shipping
- Customizable sizes, lengths, and accessories (e.g., steel rings, connectors, hanging hooks)

FAQ: Frequently Asked Questions
Q1: Can ducting fabric be used directly?
No. Ducting fabric must go through cutting, heat welding, edge sealing, and other professional processes before it becomes a usable ventilation duct.
Q2: What is the service life of flexible ducts?
Typically between 6 months and 3 years, depending on the material quality, operating environment, and frequency of use.
Q3: What certifications should I look for when purchasing industrial ventilation ducts?
For use in coal mining in China, ensure the product is certified by the “MA” Mining Safety Mark, issued by the China National Center for Safety Standard of Mining Products. This is a mandatory safety requirement for mine-use equipment.
Also consider the following:
- Flame-retardant compliance (e.g., GB/T 20490)
- Anti-static test results
- Third-party reports for air tightness, tensile strength, and aging resistance
- For export projects: optional ISO and CE certifications as needed
Q4: Do you support international shipping?
Yes. We offer global delivery, along with custom packaging, private labeling, and full export documentation services.
