Six reasons to choose circular air duct systems
1. The best quality
The products in our KEN-LOK and Spiralo ranges are durable and dimensionally stable. The seams minimise air leakage in our ducts and fittings. We offer a wide range of standardised and ETIM classified products.
2. You comply with current laws and regulations
The legislation and regulations that the construction sector has to comply with are constantly changing. By using circular ducts, you automatically meet the requirements of the NEN EN 1506 and 12237. That is one less thing for you to worry about.
3. Easier and faster installation
Circular ducts are lightweight and therefore easy to install and fit together. The KEN-LOK rubber seal makes our products Plug&Play. You do not have to use any tape. Most circular ducts are installed using a single-point suspension system rather than a two-point suspension system. All this results in you needing fewer mounting materials and saving a significant amount of time during installation. Since our ducts and fittings are in stock, we can quickly provide the right solution to any situation at your construction site.
4. Sustainable and environmentally conscious ventilation
We use a unique production method for our metal spiral-seamed ducts. The seams and the round design provide the ducts with extreme rigidity at minimal thickness. This means we use fewer materials in our production process. The round design also saves space and makes insulation easier. Due to its aerodynamic properties, the ventilation system requires less power. Did you know that our circular ducts and fittings are included in the national environmental database?
5. Healthy ventilation
A system with a round design is less susceptible to pollution and clogging because the airflow moves at virtually the same speed across the entire width of the circular ducts. Additionally, circular ducts are easier to clean.
6. Comfortable ventilation
Circular ducts create less air resistance. That, in turn, results in a lower air speed, less noise and no draught. In other words: a more comfortable interior climate.
Think circular!
Circular is better than rectangular in every way. Easier to install. Faster installation. Better, more sustainable and healthier ventilation systems.
