## Summary description

Heatpex reducer ADD 125/160/200 (ADUROADURO) is a ventilation duct fitting designed to connect ducts of different diameters. Manufactured by Heatpex, this reducer adapts between 125 mm, 160 mm and 200 mm duct sizes, enabling smooth airflow transition in HVAC installations. It is intended for residential and commercial ventilation systems to join or downsize duct runs.

## Long description

Heatpex reducer ADD 125/160/200 (ADUROADURO) is a ventilation duct fitting designed to join circular ducts of different diameters in HVAC systems. The fitting enables a controlled transition between 125 mm, 160 mm and 200 mm duct sizes, maintaining airflow continuity and compatibility across existing ductwork. It is suitable for both residential and commercial ventilation installations where ducts need to be connected, reduced or resized.
Advantages
The reducer provides a compact and stable connection between multiple standard duct diameters, reducing turbulence and pressure loss at the transition point. Made for straightforward integration with circular ventilation ducts, the fitting simplifies installation and minimises the need for custom fabrication. Its stepped profile allows installers to choose the appropriate connection size on-site, supporting flexible system design and retrofit jobs.
Suitable for
Connecting ventilation ducts of different diameters in residential HVAC systems
Adapting duct runs in commercial or light-industrial ventilation
Retrofit and repair tasks where a reduction from 200 mm to 160 mm or 125 mm is required
Temporary or permanent transitions in centralised and local exhaust systems
Key specifications
Compatible diameters: 125 mm, 160 mm and 200 mm
Type: stepped reducer for circular ventilation ducts
Application: airflow transition and duct size adaptation in HVAC systems
Typical installation location: inline within duct runs or at branch points
How to use
Select the step on the reducer that matches the upstream and downstream duct diameters and insert the ducts into the corresponding ends until a secure fit is achieved. Ensure mating surfaces are clean and free of debris, and use appropriate sealing tape, clamps or duct connectors as required by the installation standard to prevent air leakage. Verify alignment and support the duct to avoid strain on the connection; follow local ventilation codes and the broader HVAC system design when incorporating the fitting.
Usage recommendations
For effective performance, avoid sharp bends immediately adjacent to the reducer and maintain recommended clearances for inspection and access. Use compatible sealing materials and mechanical fasteners to achieve airtight joints and reduce noise and pressure loss. If adapting between widely different duct sizes, assess system resistance and, if necessary, consult HVAC documentation to confirm the reducer location will not compromise overall airflow balance.
