CDF DUCT Fans

Properties of the CDF duct fan

The CDF series duct fan with a circular impeller and backward curved blades is a lightweight solution for efficient air discharge or supply in ventilation systems, with a structure designed for easy integration into a circular duct system and quiet operation. Its unobtrusive and universal design makes it suitable for installation in shopping centres, restaurants, office buildings, hotels, and technical rooms. The fan cover provides easy access for maintenance, and a wide range of accessories allows the unit to be adapted to specific installation requirements, for example the installation of silencers, return flaps or elastic sleeves.

We offer a comprehensive design service that covers everything from calculating and planning to designing the solution.

We will launch our design application soon available directly from our website.
