Aluflex coupling fi 120mm DPO18/120

Precise connections in ventilation systems

The Aluflex coupling fi 120mm is a fundamental element of ventilation and recuperation installations, enabling the creation of airtight connections between circular aluminum ducts. This component was created for installers mounting HVAC systems as well as end users caring about the indoor environment.

The construction based on high-grade aluminum guarantees not only the durability of the connections but also natural resistance to corrosion - a key feature in environments with variable humidity. The nominal diameter of 120mm ensures compatibility with standard flexible ducts produced in the range of 32-600mm, providing full flexibility in installation design.

Materials and technical parameters

The element is made of aluminum with a thickness of 0.10-0.12mm (for flexible ducts), which translates to an optimal strength-to-flexibility ratio. Compact dimensions of 0.1 x 0.12 x 0.12m and a low weight of 0.14kg significantly facilitate installation even in hard-to-reach places.

The use of high-grade galvanized sheet metal with a thickness of 0.6mm (for rigid elements) and aluminum tape for flexible parts ensures connection stability without the risk of cracks or leakage during operation.

Application and operational benefits

The DPO18/120 coupling enables the creation of airtight connections between ventilation ducts with a diameter of 120mm, eliminating air losses and improving the overall efficiency of the air distribution system.

Thanks to the ergonomic design, installation does not require specialized tools - the installer can use a standard kit available on the market. Aluminum as a structural material provides resistance to weather conditions and corrosion processes.

An air distribution system utilizing these couplings affects the indoor environment - improving air circulation and reducing moisture in rooms.
