## Summary description

Heatpex Kolano 45° ADK 125 is a 45-degree ventilation elbow designed for ARIA and ADUROADURO duct systems with 125 mm nominal diameter. It provides a compact directional change in air ducts, suitable for residential and light commercial ventilation runs where a right-angled bend is not required. Use for redirecting airflow in supply or exhaust installations and integrating with compatible 125 mm components.

## Long description

Heatpex Kolano 45° ADK 125 is a 45-degree ventilation elbow made for ARIA and ADUROADURO duct systems with a nominal diameter of 125 mm. The elbow provides a compact change of direction for circular air ducts and is intended for use in supply or exhaust ventilation where a gentler bend than a right angle is required. The component is compatible with other 125 mm system parts designed for ARIA and ADUROADURO layouts and is suitable for installations in residential and light commercial settings.
Advantages
The elbow offers a smooth 45° curvature that reduces turbulence compared with sharp 90° bends, helping to maintain airflow efficiency in ventilation runs. Its geometry is compact, allowing directional changes in confined spaces while keeping the duct run tidy. Designed for compatibility with 125 mm components, it simplifies system design and installation when used with ARIA and ADUROADURO product lines.
Suitable for
 Residential supply and exhaust ventilation with 125 mm ducts
 Light commercial ventilation where moderate directional change is needed
 Installation runs requiring compact bends to avoid obstacles
 Integration into ARIA and ADUROADURO 125 mm duct systems
When it may not be suitable
The 45° elbow is not intended for non-ventilation uses or for duct systems with diameters other than 125 mm. For applications that require maximum airflow volume with minimal resistance, straighter ducting or larger-diameter components may be more appropriate. It is also not a direct substitute for specialized acoustic or insulated bends designed to reduce noise or thermal transfer.
Key specifications
 Curvature: 45-degree elbow for circular ducts
 Nominal diameter: 125 mm
 Intended system compatibility: ARIA and ADUROADURO 125 mm components
 Application: supply and exhaust ventilation
 Form factor: compact directional change for confined runs
How to use
Install the elbow between two compatible 125 mm duct sections, ensuring each end is fully seated and secured according to the ventilation system manufacturer's instructions. Use appropriate joining methods for the system—such as push-fit connections, clamps, or sealants—where recommended, and maintain alignment to avoid kinks or constrictions. Verify airflow direction and test the run for leaks after assembly. When routing ductwork in tight spaces, plan the sequence of bends to preserve access for inspection and future maintenance.
What to consider before purchase
 Confirm the duct nominal diameter is 125 mm and matches other system components
 Check compatibility with the ARIA or ADUROADURO product line used in the project
 Assess whether a 45° bend provides the needed change of direction versus a 90° elbow or straight section
 Consider if acoustic insulation or thermal protection is required for the installation
Usage recommendations
For optimal airflow, minimize the number of successive bends; where multiple direction changes are needed, space them out or use gradual transitions. Ensure joints are sealed and mechanically secured to prevent leakage and to maintain system efficiency. When routing near obstacles, measure clearance and plan the duct route before final assembly.
