Round vs Rectangular Ventilation Ducting: What’s the Difference?
Choosing the right ventilation ducting is essential for efficient airflow and optimal performance in HVAC systems. Two common types are round and rectangular ducting. Here’s a straightforward comparison to help you decide which is best for your needs.
Rectangular Ventilation Ducting
Rectangular ventilation ducting is designed for installations where space is limited, or height is restricted. It’s commonly used in domestic, industrial, and commercial buildings where round ducting might be too bulky.
Key Features:
- Space Efficiency: Ideal for areas with height restrictions or where large airflow is required in a small space.
- Material: Made from PVC, making it lightweight, durable, corrosion-resistant, and able to withstand higher temperatures.
- Airflow Efficiency: When installed correctly, it ensures minimal air leakage and pressure drop, delivering reliable performance.
- Applications: Favoured for kitchens, bathrooms, and areas where compact solutions are necessary.
Available Sizes:
- 110mm x 54mm
- 204mm x 60mm
- 220mm x 90mm
Round Ventilation Ducting
Round ventilation ducting is commonly used with extractor fans in kitchens and bathrooms. It offers excellent airflow efficiency due to its smooth internal design, which reduces resistance.
Key Features:
- Easy Installation: Designed with a push-fit connection system, where the female ends of the pipe fit over the male ends of the fittings.
- Material: Made from PVC, offering durability, lightweight construction, and resistance to corrosion and high temperatures.
- Airflow: The smooth bore promotes efficient airflow, making it suitable for high-performance applications.
- Applications: Perfect for domestic extractor fan systems and environments requiring efficient air circulation.
Available Sizes:
- 100mm diameter
- 125mm diameter
- 150mm diameter
Key Differences
- Shape: Round ducting provides better airflow efficiency due to reduced turbulence, while rectangular ducting is better for tight spaces and height-constrained installations.
- Applications: Round ducting is ideal for extractor fans in kitchens and bathrooms, while rectangular ducting works well in domestic, industrial, and commercial environments where compact solutions are needed.
- Ease of Installation: Round ducting offers a simpler push-fit design, while rectangular systems are more suited for customised setups.
Which One Should You Choose?
- Choose rectangular ducting if you have limited space or need a system that can handle large airflow in small, height-restricted areas.
- Choose round ducting for better airflow efficiency, especially in standard kitchen or bathroom extractor fan installations.
Both options are available in a range of sizes and configurations, ensuring you can find the perfect solution for your ventilation needs.
