Double coupling ComfoPipe Compact DN 125 D=185/155 990328760

Universal Coupling for ComfoPipe Ventilation Systems

This double ComfoPipe Compact DN 125 coupling is a key component for connecting ventilation duct sections, especially in situations requiring precise alignment or utilization of leftover material. It ensures a tight, durable connection, minimizing air leakage and guaranteeing efficient operation of the entire ventilation system. This solution is ideal for both professional ventilation installers and end-users who install or expand systems independently.

The coupling is manufactured from high-quality expanded polypropylene (EPP), providing lightweight durability and excellent insulating properties. This reduces condensation inside ducts, preventing mold and fungal growth. Its design enables easy installation and removal, simplifying maintenance and potential system modifications.

Features and Applications

The ComfoPipe Compact DN 125 coupling is designed for Zehnder ComfoPipe ventilation systems. However, due to its standard dimensions (nominal diameter 125 mm), it is also compatible with other compatible ventilation ducts. Its versatility makes it ideal for:

• Connecting duct sections: Enables seamless joining of two 125 mm ventilation ducts without additional connecting elements.
• Utilizing leftover material: Allows efficient use of shorter duct fragments, minimizing waste.
• Repairing damaged sections: Facilitates quick and easy replacement of damaged duct segments.
• Building branch connections: When combined with other ComfoPipe components, enables creation of ventilation system branches.

The working length of the coupling is 10 mm, with an insertion depth of 45 mm on each side. Insulation thickness is 12 mm, further enhancing the system’s thermal insulation. The coupling does not come with a pre-installed seal—this allows flexibility in selecting the appropriate sealing solution based on installation specifics.

Product Advantages

• Fast and easy installation: Thanks to its simple design and “click” system, installation is quick and intuitive—saving time for both installers and end-users.
• Leak-tight connection: Ensures airtight duct connections, minimizing air loss and optimizing system performance.
• Durability and resistance: Made from high-quality EPP, the coupling resists mechanical damage and corrosion, ensuring long-term reliability.
• Insulating properties: 12 mm insulation thickness reduces condensation inside ducts, preventing mold and fungal growth.
• Universal compatibility: Compatible with Zehnder ComfoPipe systems and other standard 125 mm ventilation ducts.
• Warranty: Covered by a two-year manufacturer’s warranty from Zehnder, confirming its high quality and reliability.
