## Summary description

Diffusor Box DN160-12x75 by Dedra is a ventilation accessory designed for inline installation in round duct systems with nominal diameter DN160. The unit incorporates a 12×75 mm element configuration to reduce air flow noise and improve diffusion. Suitable for HVAC exhaust or supply lines where noise attenuation and even air distribution are required in residential or light commercial installations.

## Long description

Diffusor Box DN160-12x75 Dedra is an inline ventilation silencer designed for installation in circular ductwork with a nominal diameter of DN160. The unit contains a 12×75 mm element configuration that reduces airflow noise while promoting more uniform air diffusion along the duct. It is intended for use in residential and light commercial HVAC supply or exhaust lines where lower acoustic levels and improved distribution are required.
Advantages
The device combines sound attenuation and air diffusion within a compact, cylindrical housing compatible with DN160 duct systems. Its 12×75 mm element layout provides consistent pressure drop characteristics while targeting broadband noise commonly generated by fans and turbulent flow. The silencer is suitable for inline installation and does not require additional acoustic enclosures, allowing easier integration into existing ventilation runs.
Suitable for
DN160 round duct HVAC supply air lines
DN160 round duct HVAC exhaust channels
Residential ventilation systems where noise reduction is needed
Light commercial applications such as small offices or retail spaces
Key specifications
Design: inline circular silencer for DN160 ducts
Internal element configuration: 12 × 75 mm elements for diffusion and noise attenuation
Function: reduces airflow noise and improves air distribution
Typical installation position: inline within straight duct runs
Application environment: supply or exhaust ventilation in residential and light commercial buildings
How to use
Install the Diffusor Box directly into the DN160 circular duct run in a straight section to maintain intended acoustic performance. Ensure duct ends are clean and properly aligned before connecting; use appropriate clamps, flanges, or duct connectors suitable for DN160 to secure the unit. Maintain the recommended straight inlet and outlet lengths as specified by local HVAC practice to avoid flow disturbances. Periodically inspect the silencer for accumulated dust or debris and clean according to the maintenance schedule of the ventilation system.
Usage recommendations
Position the device at a distance from fans and bends that allows stable flow conditions—this typically improves noise attenuation and ensures even diffusion. When used in systems with filters or heat recovery units, verify compatible flow rates and pressure drop to maintain overall system performance.
