Product information

Description

The Duct extension for distribution box DN 125 Zehnder is a tubular ventilation fitting designed to extend the length of ductwork and provide a secure connection to round distribution (junction) boxes with a nominal diameter of DN 125. Manufactured by Zehnder, this extension is intended for use in mechanical ventilation systems where increased reach or adjusted spacing between components is required. The component connects to DN 125 round ducts and distribution boxes, maintaining airflow continuity and compatibility with standard DN 125 system parts.

Advantages

This duct extension offers dimensionally accurate connections for DN 125 systems, reducing the need for custom cutting or on-site fabrication. The product is suited to maintain airtight joints when properly installed and assists in simplifying duct routing through walls, ceilings, or between stacked ventilation components. Its design supports consistent internal diameter for minimal airflow disruption and enables modular system adjustments during installation or renovation.

Suitable for

  • Extending DN 125 duct runs in residential mechanical ventilation systems
  • Connecting DN 125 round ducts to distribution or junction boxes
  • Adjusting spacing in commercial HVAC installations with DN 125 components
  • Retrofitting or renovating ventilation layouts that require additional duct reach

Key specifications

  • Nominal diameter: DN 125 (compatible with DN 125 round ducts and junction boxes)
  • Function: tubular extension for ventilation distribution box connections
  • Application: mechanical ventilation systems in residential and commercial buildings
  • Material characteristics: manufactured to maintain internal airflow continuity (follow manufacturer material specification sheet)
  • Connection type: designed for straightforward coupling to round ducts and distribution boxes with matching diameter

How to use

Measure the required extension length and verify compatibility with existing DN 125 distribution boxes and ducts before installation. Align the extension concentrically with the mating distribution box or duct and insert until the joint seats fully. Secure the connection according to local installation practices and applicable sealing methods, such as clamps, seals, or approved duct tape, to ensure airtightness. Confirm that the extended run does not obstruct airflow and that the assembly is supported to prevent stress on adjacent components.

Usage recommendations

Install the extension in compliance with applicable ventilation standards and Zehnder installation guidance. Use appropriate sealing and mechanical supports to preserve airtightness and reduce vibration or noise transmission. Inspect joints after installation and during routine maintenance to ensure continued performance and to detect any loosening or leaks.
