Product information

Description

The Diffusor Box DN125-9x75 is a high-quality ventilation component engineered for precise air distribution in mechanical ventilation systems. Designed to facilitate seamless airflow, this unit serves as a critical junction point in ductwork, allowing for efficient air supply or extraction. Its robust construction ensures long-term reliability in both residential and commercial building environments, making it an essential element for maintaining balanced indoor air quality.

Advantages

This diffusor box offers exceptional versatility by connecting a primary DN125 duct to nine individual 75mm flexible ducts. The streamlined design minimizes air resistance, which helps in reducing noise levels and improving the overall energy efficiency of the ventilation system. Its compact form factor allows for easy installation in tight spaces, such as suspended ceilings or wall cavities, while the durable materials provide resistance to mechanical stress and environmental factors.

Suitable for

  • Residential mechanical ventilation systems with heat recovery
  • Commercial office air distribution networks
  • New construction projects requiring flexible duct routing
  • Retrofitting existing ventilation setups for improved airflow

When it may not be suitable

This unit is not intended for use in high-temperature industrial exhaust systems or environments where the air contains corrosive chemicals or heavy particulate matter that could clog the ports. It is also not suitable for systems requiring duct diameters other than the specified 125mm main connection or 75mm branch connections.

Key specifications

  • Main connection diameter: 125 mm
  • Branch connection ports: 9 x 75 mm
  • Material: Durable synthetic construction
  • Application: Air supply and extraction

How to use

Installation should be performed by connecting the main 125mm ventilation duct to the primary inlet of the box, ensuring an airtight seal using appropriate duct tape or clamps. The nine 75mm ports should then be connected to the corresponding flexible ventilation ducts leading to individual rooms or diffusers. Ensure that all connections are properly secured and that the box is mounted firmly to the building structure to prevent vibration during operation.

What to consider before purchase

  • Verify that your existing ventilation system uses 125mm main ducts and 75mm branch ducts.
  • Ensure there is sufficient physical space in the ceiling or wall cavity for the box dimensions.
  • Check the total airflow requirements of your system to ensure this box can handle the necessary volume.

Usage recommendations

Regularly inspect the connections during routine maintenance to ensure they remain airtight and free from debris. It is recommended to balance the system after installation to ensure optimal airflow distribution across all nine ports.
