Spiral Ducting for Efficient Ventilation Systems
Spiral ducting is one of the most efficient and widely used solutions for modern industrial and commercial ventilation systems. Known for its strength, airflow performance and cost-effectiveness, spiral ductwork is commonly used in factories, workshops, warehouses and HVAC installations.
Unlike traditional rectangular duct systems, spiral ducting is manufactured from a continuous strip of galvanised steel, which is formed into a rigid spiral tube. This manufacturing method increases the structural strength of the duct while using less material, making spiral ductwork both durable and economical
Another key advantage of spiral ducting is improved airflow efficiency and sealing performance. The round shape reduces air resistance compared with rectangular ducting, helping ventilation systems operate more efficiently.
Spiral ducting is also designed with female ends, allowing compatible male duct fittings such as bends, connectors and dampers to slide directly into the duct. This makes installation faster, simpler and more secure.
Because of these benefits, spiral ducting has become the preferred choice for commercial ventilation, dust extraction systems and HVAC installations.
Spiral Ducting Sizes to Suit Your Requirements
Choosing the correct spiral duct size is essential for achieving the best airflow and system performance.
We supply spiral ducting in a wide range of sizes to suit different ventilation and extraction systems, with diameters available from 100mm to 1600mm. All sizes are measured by the internal diameter of the duct, ensuring compatibility with standard duct fittings and accessories.
Having a variety of spiral duct sizes available allows you to design a system that matches the airflow requirements of your building or process.
If you are unsure which spiral duct diameter you require, our experienced team can help. We are happy to advise on duct sizing, fittings and system design to ensure you select the correct components for your ventilation system.
Installing Spiral Ductwork
Correct planning and installation are essential for any spiral ductwork ventilation system.
Before installing spiral ducting, it is important to consider several factors including the layout of the building, airflow requirements, support systems, insulation and the type of duct fittings required. Proper planning helps ensure the system runs efficiently and meets industry standards.
Spiral ducts themselves are female components, which means male duct fittings such as bends, reducers, connectors and dampers are designed to fit neatly inside the duct. This connection method allows for quick assembly and a reliable seal between components.
A well-designed spiral duct system will improve airflow performance, reduce leakage and ensure long-term reliability.
If you need advice on spiral duct installation, duct fittings or ventilation system design, the specialists at JacoVent are always available to help. Our team can guide you through the process and ensure you have the right components for a professional installation.
