Expansion tank CLF 990322210

Ventilation system expansion box

The CLF expansion box from Zehnder is an element of the air distribution system, designed for connecting Flat 51 flat ducts at a 90° angle. It is a key component in heat recovery ventilation systems, enabling efficient air distribution inside the building. The product is dedicated to both professional installers and end customers looking for reliable solutions in mechanical ventilation with heat recovery.

Construction and application

The CLF box is designed for easy mounting on the wall, floor or ceiling. The RapidLock RL latch provides a quick and secure connection of ventilation duct elements. The lack of a gasket in the set requires its separate purchase, allowing adaptation to specific installation conditions. Its compact dimensions (0.22 x 0.32 x 0.22 m) and low weight (approximately 0.6 kg) facilitate transport and installation even in hard-to-reach places.
