Broming’s Spiral Duct
Whether you’re working with industrial ventilation, commercial HVAC, or any specialized application, our Spiral Ducts are engineered to provide efficient airflow, durability, and seamless integration into your system.
Spiral Ducts are an advanced solution for efficient and reliable air distribution in HVAC systems. Their unique design and robust construction make them the preferred choice for various industrial, commercial, and residential applications. Let’s explore the key features and the scenarios where Spiral Ducts truly excel.
1. Enhanced Durability and Strength
Spiral Ducts are constructed with a spiral seam, providing exceptional strength and resistance to external pressure, making them more durable than standard rectangular ducts. This feature is especially beneficial in systems where ducts are exposed to physical stresses, such as in industrial or high-traffic environments.
2. Superior Airflow Efficiency
The smooth, circular shape of Spiral Ducts reduces airflow resistance and turbulence, leading to smoother and more efficient air distribution. This improves the overall efficiency of HVAC systems, which can result in lower energy consumption and reduced operating costs for businesses.
3. Space-Saving Design
The compact, cylindrical design of Spiral Ducts allows them to fit into tighter spaces and be more flexible in design. This is particularly useful for installations in areas with limited space, such as ceiling voids, narrow shafts, or retrofit projects where existing infrastructure limits options.
4. Reduced Noise and Vibration
Due to their smooth inner surface and structural integrity, Spiral Ducts help minimize noise and vibration within HVAC systems. This makes them a preferred choice for environments where maintaining a quiet atmosphere is critical, such as office buildings, hospitals, and educational institutions.
5. Easy Installation and Customization
The flexibility of Spiral Ducts allows for easy customization in terms of size, material, and length to fit specific system requirements. Additionally, their modular design allows for quick and hassle-free installation, reducing labor costs and installation time.

Applications & Manufacturing of Spiral Duct
Rectangular ducts are widely used in HVAC projects that demand large air volume and high structural stability.
Each rectangular duct is fabricated from prime galvanized steel coils using automated cutting and folding machines.
The production process ensures tight dimensional tolerance, reinforced seams, and high leak-tightness.
