## Summary description

SpiroFlex duct adapter for 80/125 mm circular ducts, designed for connection and airflow measurement. The adapter includes integrated measurement nozzles (kroćce) to allow insertion of probes or manometers for pressure and flow diagnostics. Finished in white, it is suitable for ventilation and HVAC installations where monitoring and testing of duct performance is required.

## Long description

SpiroFlex duct adapter 80/125 with measurement nozzles, white is a circular duct transition element intended for ventilation and HVAC systems. It connects an 80 mm duct to a 125 mm duct while providing integrated measurement nozzles that permit insertion of probes or manometers for pressure and airflow diagnostics. The white finish matches typical ductwork and technical rooms where a low-profile, functional connection with diagnostic access is needed.
Advantages
The adapter combines a smooth transition between two circular duct sizes with built-in measurement nozzles, reducing the need for separate diagnostic fittings. Its integrated nozzles allow straightforward insertion of testing instruments without interrupting the airflow path, and the white surface simplifies visual inspection and compatibility with common ventilation components. The design minimizes turbulence at the connection and supports routine performance checks and commissioning procedures.
Suitable for
Residential and commercial ventilation systems requiring size transition between 80 mm and 125 mm ducts
HVAC commissioning, airflow balancing and pressure diagnostics
Maintenance tasks that require repeated insertion of probes or manometers
Situations where a discrete white finish is preferred for visible ductwork
Key specifications
Connection diameters: one end for 80 mm circular duct and one end for 125 mm circular duct
Integrated measurement nozzles allowing probe or manometer access
Colour: white finish for visual compatibility with ducting
Material: durable ventilation-grade material suitable for indoor HVAC use
Function: duct size transition with diagnostic access for airflow and pressure measurement
How to use
Install the adapter by securing each end to the corresponding circular duct using appropriate clamps, seals or fittings for the ductwork in use. Ensure the connection is airtight to prevent leaks that could affect airflow measurements. To perform measurements, insert the probe or manometer tubing into the integrated measurement nozzles to the depth required by the instrument manufacturer, taking care to follow safe handling and instrument calibration procedures. After testing, remove instruments and reseal nozzles if necessary to maintain system integrity.
Usage recommendations
Use compatible clamps and sealing methods to maintain airtight connections. When performing diagnostic measurements, follow the probe or manometer manufacturer’s instructions for insertion depth and calibration to ensure accurate readings. For repeated testing, inspect the measurement nozzles periodically for wear or damage and replace the adapter if the integrity of the connection is compromised.
