## Long description

Dedra DIFFUSOR BOXDN125-9X75 is a ventilation diffuser designed for connection to DN125 (125 mm) circular ducts. The diffuser features a 9×75 grille configuration that distributes supply or extract air evenly into rooms served by mechanical ventilation systems. It is suitable for compact residential and light commercial installations where a DN125 duct connection is specified and a reliable, low-profile terminal is required.
Advantages
The unit provides uniform air distribution through nine evenly spaced outlets and a 75 mm spacing pattern, helping to reduce draft and improve comfort. Its circular DN125 connection ensures compatibility with common 125 mm ductwork and flexibilty in retrofit or new installations. The design is compact and intended for easy mounting and integration with standard ventilation lines, minimizing installation time and need for additional adapters.
Suitable for
Residential supply and extract ventilation in apartments and houses
Light commercial ventilation in small offices or service rooms
Retrofit projects replacing or upgrading DN125 duct terminals
Applications requiring a compact diffuser for a 125 mm circular duct
Key specifications
Connection diameter: compatible with DN125 (125 mm) circular duct
Grille configuration: 9 outlets with 75 mm spacing pattern
Function: air supply and extract distribution for mechanical ventilation
Installation: ceiling or wall terminal compatible with standard ductwork
How to use
Install the diffuser into a DN125 circular duct termination, ensuring a secure fit and proper alignment with the ventilation run. Use appropriate mounting or sealing methods to prevent air leakage at the joint. Adjust the downstream ventilation system or dampers as required to achieve the desired airflow distribution; the 9×75 configuration is designed to provide broad dispersion without further adjustment in many typical applications.
Usage recommendations
Check compatibility with the existing DN125 ductwork before installation. For best performance, combine the diffuser with balanced mechanical ventilation and periodic cleaning to prevent dust accumulation on the grille openings.
