Three-port expansion box straight-through 3x75/125 SK3X75/125P

Expansion box – a key element of the ventilation installation

The expansion box is an indispensable component in every ventilation system, used for efficient air distribution and connection of air diffusers. The 3x75/125 model, made of durable plastic, ensures reliable operation and easy installation. This is particularly important for both professional installers and end-users who value comfort and ventilation system efficiency.

Construction and application

This three-port through expansion box is designed to connect three ventilation ducts with a diameter of 75 mm and an air diffuser with a diameter of 125 mm. Its construction allows for even distribution of airflow, minimizing pressure loss and ensuring optimal system performance. The KLIK system cuffs and factory-installed seals significantly speed up and simplify the installation of PE-FLEX® ducts, while guaranteeing the tightness of the installation. The possibility of directly connecting an air diffuser or using an extension (123 mm) provides flexibility in adapting to specific installation needs.

Advantages and benefits

• Quick installation: The KLIK system and factory-installed seals eliminate the need for additional sealing materials and shorten installation time.
• Tightness: Guaranteed tightness of connections thanks to the precise execution of the cuffs and the use of high-quality seals. This translates to lower energy losses and more efficient ventilation system operation.
• Versatility: The ability to connect an air diffuser directly or using an extension provides flexibility in installation design.
• Durability: Made of durable plastic, resistant to mechanical damage and weather conditions.
• Hygiene: Has a hygiene certificate from the State Sanitary Inspectorate (BK/K/0153/01/2018), which confirms safety of use in contact with breathing air.
• Uniform airflow: The box design ensures even distribution of pressure and airflow, which translates to comfort in the use of rooms.

The box is characterized by a height of the green body of 6 cm, a height of the connecting cuff of 8.8 cm, a width without mounting brackets of 28.2 cm, a width with mounting brackets of 30.5 cm, a depth without a mounting bracket of 24 cm and a depth with a mounting bracket of 30 cm.

It is worth remembering that the expansion box not only facilitates installation, but also affects the efficiency of the entire ventilation system, ensuring optimal microclimate conditions in the rooms. Therefore, investing in a high-quality expansion box is a guarantee of comfort and energy savings.
