Transition from ComfoTube 90/75 to ComfoTube flat 51 990322204

Transition between ventilation duct systems

This practical transition allows for a smooth connection between a round ComfoTube 90/75 duct and a flat ComfoTube flat 51 duct. This adapter provides flexibility during installation, allowing adaptation to specific construction conditions and easy changing of the duct cross-section if necessary. It is particularly useful during installation modernization or in situations where connecting different types of ducts is required.

Construction and assembly

The transition is equipped with the RapidLock RL system, which guarantees quick and secure assembly without the need for additional tools. The lack of seals simplifies the installation process and minimizes the risk of errors. The double mounting collar ensures a stable and tight connection with both types of ducts, which translates into the efficiency of the entire ventilation system. This allows installers to save time and resources, and end-users to gain confidence in the reliable operation of the system.

Application and compatibility

The transition is intended for use with the Zehnder ComfoTube ventilation duct system. It is an ideal solution in situations where it is necessary to connect round ducts with a diameter of 90/75 mm with flat ComfoTube flat 51 ducts. It can be used both in new installations and during the modernization of existing ventilation systems. It ensures compatibility with other elements of the Zehnder system, such as ventilation units, distribution boxes and air diffusers, creating a coherent and efficient whole.
