Diffusor Box DN160-12x75 for Ventilation Systems

The DN160-12x75 diffusor box is a high-quality ventilation component engineered for precise air distribution within modern air handling systems. Designed to serve as a central junction point, this unit facilitates the connection between a primary 160 mm ventilation duct and up to 12 flexible 75 mm ducts. Its durable construction ensures structural integrity and consistent airflow performance, making it an essential element for maintaining healthy indoor air quality in both residential and commercial buildings.

Advantages

This diffusor box offers significant benefits for ventilation network efficiency by providing a streamlined transition from main supply lines to individual room outlets. The robust design minimizes pressure drops and turbulence, ensuring that air is distributed evenly throughout the system. Its compact form factor allows for versatile installation in tight spaces, such as ceilings or wall cavities, while the multiple port configuration provides flexibility for complex ductwork layouts. The high-quality materials used in its production guarantee long-term reliability and resistance to mechanical stress during installation and operation.

Suitable for

• Residential ventilation systems
• Commercial office air distribution
• Multi-room air supply networks
• New construction and renovation projects

When it may not be suitable

This unit is specifically designed for 160 mm main ducts and 75 mm flexible ducting. It may not be suitable for systems requiring larger diameter main connections or those utilizing rigid ducting systems that do not accommodate the 75 mm port configuration.

Key specifications

• Main connection diameter: 160 mm
• Number of flexible duct ports: 12
• Flexible duct diameter: 75 mm
• Material: Durable synthetic construction

How to use

Installation involves connecting the 160 mm main ventilation duct to the primary inlet of the diffusor box, ensuring an airtight seal. The 75 mm flexible ducts are then attached to the 12 available ports, securing them with appropriate clamps or connectors to prevent air leakage. The box should be mounted securely to the building structure using suitable brackets to prevent vibration and ensure stability. Once connected, the system should be balanced to ensure optimal airflow to each individual room.

What to consider before purchase

• Verify the diameter of your existing main ventilation duct
• Ensure the number of required flexible duct runs matches the 12-port capacity
• Check available space in the installation area for the box dimensions
• Confirm compatibility with your specific flexible ducting system

Usage recommendations

Regularly inspect the connections during routine maintenance to ensure all seals remain tight and the system continues to operate at peak efficiency without air leaks.
