Expansion tank three-port 3x75/125 (rectangular) SK3X75/125

Expansion box – a key element of efficient ventilation

The expansion box 3x75/125 is an indispensable component in ventilation systems, especially in heat recovery installations. It serves to distribute airflow and connect pipes of different diameters, ensuring even air distribution throughout the building. It is an element connecting ventilation pipes with a diameter of 75 mm with a spigot for an air diffuser with a diameter of 125 mm.

Construction and application

The construction of the expansion box allows for effective reduction of air flow resistance, which translates to quieter system operation and lower energy consumption by ventilation units. The box is particularly useful in places where it is necessary to connect several pipes into one or direct the airflow in different directions. This allows installers to flexibly adapt the ventilation system to the specifics of each building.

It is worth remembering that expansion boxes find their application on both the supply and exhaust sides of the installation. They allow the connection of flexible pipes and air diffusers, providing a tight and durable connection. Thanks to this, the ventilation system works efficiently and effectively for a long time.

Product advantages

• Versatility: Possibility of connecting pipes of different diameters (75 mm) and air diffusers (125 mm).

• Easy installation: The construction facilitates quick and trouble-free installation in the ventilation system.

• Durability: Made of durable materials, guaranteeing long life and resistance to damage.

• Airflow optimization: Reduces air flow resistance, improving the efficiency of the ventilation system.

• Tightness: Provides a tight connection of pipes, minimizing air losses and ensuring efficient system operation.

• Compatibility: Fits standard corrugated ventilation pipes with a diameter of 75 mm.

For installers – practical aspects of installation

The expansion box 3x75/125 is compatible with various types of ventilation pipes, providing a great deal of freedom during installation. Remember to use appropriate seals (often included in the set) to ensure the tightness of the connections. Stable mounting is crucial for proper system operation – use the mounting brackets available in the box or additional mounting elements adapted to the specifics of the substrate. This will avoid unwanted vibrations and noise during system operation.
