## Summary description

SpiroFlex 60/100-80/125 adapter AR (model SX-TD-AARB) is a white ventilation duct transition fitting designed to connect round ducts of 60/100 mm to 80/125 mm. Made for HVAC installations, it provides a secure link between differing duct sizes, ensuring airflow continuity and compatibility with ACV and ILEA systems in residential or commercial ventilation setups.

## Long description

SpiroFlex adapter 60/100-80/125 AR white (model SX-TD-AARB) is a ventilation duct transition fitting designed to join round ducts with different diameters. The adapter converts a duct section of 60/100 mm to 80/125 mm, offering a compact solution for connecting ventilation components in residential and commercial HVAC systems. The white finish is suitable for visible installations where a neutral appearance is required and the design supports compatibility with ACV and ILEA systems.
Advantages
The adapter provides a secure mechanical connection between mismatched round ducts, preserving airflow continuity while reducing turbulence at the junction. Its compact shape and standardized diameters simplify installation without requiring additional custom parts. The white surface reduces visual contrast in finished interiors and can be painted or trimmed to match surrounding finishes if needed.
Suitable for
 Connecting round ventilation ducts from 60/100 mm to 80/125 mm in HVAC systems
 Retrofit projects where existing ductwork of different sizes must be integrated
 Residential and light commercial ventilation installations compatible with ACV and ILEA components
When it may not be suitable
This adapter is intended for round duct transitions between the specified diameters; it is not suitable for connecting non-round (rectangular) ducts or for transitions requiring sound attenuation, thermal insulation, or fire-rated barriers. For systems with strict airtightness, acoustic, or fire-safety requirements, additional components or alternative certified fittings may be required.
Key specifications
 Transition diameters: from 60/100 mm to 80/125 mm
 Shape: round-to-round duct adapter
 Finish: white
 Application: ventilation/HVAC ductwork
 Compatibility: designed for use with ACV and ILEA ventilation components
How to use
Position the adapter so each end aligns with the corresponding duct diameters, insert ducts fully onto the adapter ends, and secure with appropriate clamps, clips, or sealing tape according to installation practice. Ensure joints are aligned to avoid kinks or gaps that could impede airflow. After mechanical fixation, check for leaks and make any necessary adjustments to achieve a continuous, unobstructed airflow path.
What to consider before purchase
 Confirm the exact duct diameters and that one side of the duct is compatible with the adapter’s 60/100 mm and the other with 80/125 mm
 Verify compatibility with existing ACV or ILEA components in the ventilation system
 Assess whether additional sealing, insulation, or fire-rated fittings are required for your installation
Usage recommendations
Use appropriate mechanical fasteners and HVAC sealing materials to secure and seal connections. Inspect joints after installation and during routine maintenance to ensure persistent airtightness and unobstructed airflow. If the installation requires noise reduction or thermal isolation, incorporate dedicated silencers or insulated duct sections.
