Distribution box 51/4 990322220

Ventilation system distribution box – central air distribution point

The Zehnder 51/4 distribution box is a key element in air distribution systems, especially in installations with heat recovery. It is used to branch ComfoTube flat 51 air ducts, enabling efficient air distribution in different rooms. Its compact dimensions (0.08 x 0.45 x 0.31 m) and low weight (1.12 kg) facilitate installation and integration with existing infrastructure.

Construction and application

Equipped with RapidLock RL clips, the box provides quick and secure mounting of ComfoTube flat 51 flat ducts. The set includes 4 RL clips dedicated to mounting the ducts. The lack of seals means that the box is intended for systems where tightness is ensured at other stages of installation – e.g. by properly connecting the ducts and sealing elements. This solution works where ease of installation and disassembly for service purposes is a priority.

Advantages for installers and users

• Quick installation: The RapidLock RL system significantly speeds up the installation process of flat ducts, saving time and labor costs.
• Compatibility: The box is dedicated to ComfoTube flat 51 ducts, guaranteeing a perfect fit and airtight connections (when using appropriate seals).
• Compact dimensions: Allow installation in limited space, without the need for complex adaptation work.
• Easy servicing: RapidLock RL clips allow for quick and easy removal of ducts for maintenance or repair.
• Durable construction: Made of high-quality materials ensures long-lasting and reliable operation of the ventilation system.
• Airflow optimization: Thanks to the precise design, the box minimizes air flow resistance, which translates into the efficiency of the entire ventilation system.

The 51/4 distribution box is a reliable solution for professionals involved in the installation of ventilation systems and for users who value the comfort and energy efficiency of their homes. It is an essential element for the proper functioning of the heat recovery unit and ensuring optimal air quality in the rooms.
