Single-port expansion tank 1x90/125 (rectangular) SK1X90/125

Expansion box – a key element of efficient ventilation

The single-branch expansion box, designed for ventilation systems, especially heat recovery units, serves to optimally distribute air and equalize pressure in the installation. Its task is to ensure a stable airflow, minimize resistance, and reduce noise. This solution is proven both in new installations and in the modernization of existing ventilation systems.

Construction and application

Made of durable plastic – polypropylene – the box is characterized by solidity and long-term reliability. Its construction has been reinforced, which increases resistance to mechanical damage. The box has a 90 mm nozzle and a 125 mm main connection, allowing for flexible adaptation to various ventilation duct configurations. The possibility of cutting and shortening the box further facilitates installation in tight spaces. It can be used on both the exhaust (used air) and supply side of the installation.

Advantages and benefits

• Noise reduction: The special internal shape of the box muffles sound and stabilizes airflow, which translates to quieter operation of the ventilation system.
• Resistance minimization: The box design has been optimized to reduce air flow resistance, increasing the energy efficiency of the heat recovery system.
• Antibacterial properties: The addition of silver particles provides antibacterial and biocidal properties, limiting the development of microorganisms inside the ventilation ducts.
• Antistatic properties: The antistatic material prevents dust and dirt from settling inside the box.
• Tightness: The circumferential gasket guarantees a tight connection of the ventilation ducts, eliminating the risk of uncontrolled air leakage.
• Easy installation: The simple construction allows for quick and easy installation of the box without the need for specialized tools.
• Durability: Used nanomaterials improve the mechanical and visual properties of the product, ensuring its long-term operation.
• PZH certificate: The product has a PZH certificate, confirming its safety for users.

Thanks to these features, the Max-Vent expansion box is a reliable solution for professional installers and demanding end customers who value comfort, energy efficiency, and high air quality in their home or workplace.
