## Summary description

GBC AIR DISTRIBUTION BOXSLIM DN125-2X75 is an air distribution box designed to split an incoming DN125 duct into two DN75 outlets. The unit facilitates ventilation branch distribution in HVAC systems, allowing connection of a main duct to two smaller ducts. Suitable for residential and light commercial ventilation routing and retrofit installations where compact distribution is required.

## Long description

GBC AIR DISTRIBUTION BOXSLIM DN125-2X75 is a compact air distribution box designed to split an incoming DN125 duct into two DN75 outlets. Intended for use in ventilation systems, the unit provides a straightforward method to branch a main supply or extract duct into two smaller runs while preserving airflow characteristics. Its slim profile and simple geometry make it suitable for installations in limited spaces and for retrofit projects where space and accessibility are constrained.
Advantages
The distribution box offers a compact footprint and straightforward connection points that simplify duct routing and reduce installation time. Made to work with standard round ducts, it ensures consistent airflow division between two DN75 outlets and helps maintain system balance when used with appropriate ducting and diffusers. The slim design supports installation in shallow ceiling voids or narrow service spaces without requiring complex modifications.
Suitable for
Branching a main DN125 ventilation duct into two DN75 supply or extract ducts
Residential ventilation systems and small commercial HVAC applications
Retrofit installations where a compact distribution solution is needed
Routing ducts in limited-depth ceiling voids or narrow service spaces
Key specifications
Inlet diameter: DN125
Outlet diameters: 2 × DN75
Form factor: slim, round-to-dual-round distribution unit
Intended application: air distribution for ventilation systems
Compatibility: standard round ducts of corresponding diameters
How to use
Install the distribution box inline with the main DN125 duct so the inlet receives the primary airflow. Connect two DN75 ducts to the outlet sockets, ensuring secure mechanical joins and appropriate sealing to prevent leakage. Position the unit so that it remains accessible for inspection and, if necessary, cleaning. Integrate with existing ductwork and diffusers according to the ventilation design to maintain desired airflow and balance across branches.
Usage recommendations
Verify airflow requirements and balance when splitting a main duct; use dampers, balancing devices or airflow measurement tools downstream if precise airflow distribution is required. Ensure all connections are sealed and supported to avoid sagging or air leaks. Confirm material compatibility with the surrounding HVAC components and allow sufficient clearance for installation and future access.
