Flexible Industrial Air Duct Manufacturer – High Performance Ventilation Solutions
A flexible industrial air duct is an essential component in modern industrial ventilation and air movement systems. Compared with rigid ducting, flexible air ducts offer superior adaptability, ease of installation, and cost efficiency, especially in complex or temporary industrial environments.
DERFLEX is a professional manufacturer specializing in heavy duty flexible industrial air duct systems. With extensive experience in coated fabric technology and industrial ventilation materials, DERFLEX supplies reliable air ducting solutions to customers across manufacturing, construction, mining, HVAC, and infrastructure sectors worldwide.
What Is a Flexible Industrial Air Duct?
A flexible industrial air duct is a collapsible ventilation conduit designed to transport fresh air, exhaust air, dust, fumes, or gases in industrial and commercial environments. It is typically constructed from reinforced PVC-coated fabric or technical textiles combined with a steel wire helix or reinforced structure.
Unlike rigid metal ducting, flexible air ducts can bend, compress, and extend, allowing for fast installation in confined spaces, uneven layouts, and mobile ventilation systems. This flexibility makes them especially suitable for industries where layouts change frequently or temporary ventilation is required.
DERFLEX Flexible Industrial Air Duct Product Portfolio
Heavy Duty Flexible Air Duct
Designed for continuous industrial use, heavy duty flexible air ducts feature thick coated fabrics, reinforced seams, and strong wire helix support to maintain shape under high airflow and pressure.
PVC Flexible Industrial Air Duct
PVC-coated flexible air ducts provide excellent resistance to moisture, chemicals, and abrasion. The smooth internal surface minimizes airflow resistance, improving ventilation efficiency.
Flame Retardant Flexible Air Duct
For high-risk environments such as tunnels, mines, and enclosed workspaces, DERFLEX offers flame-retardant flexible air ducts compliant with international fire safety standards.
Portable Ventilation Duct
Lightweight and collapsible, portable flexible air ducts are ideal for temporary ventilation in construction sites, maintenance operations, and emergency airflow applications.
