## Long description

The DARCO RDS 125/100 duct reducer is a precision-engineered component specifically designed for hot air distribution systems. It facilitates a smooth and secure transition between ventilation ducts with diameters of 125 mm and 100 mm. Built to withstand the demanding conditions of heating and ventilation installations, this reducer ensures optimal airflow efficiency and structural integrity within professional HVAC networks.
Advantages
This duct reducer offers exceptional thermal resistance, making it an ideal choice for systems transporting heated air. Its robust construction ensures a tight, leak-proof connection that maintains system pressure and prevents energy loss. The design promotes streamlined airflow, reducing turbulence and noise within the ductwork, while its standardized dimensions allow for quick and easy integration into existing ventilation setups.
Suitable for
Hot air distribution systems
Fireplace heat distribution installations
Residential and commercial ventilation networks
Adapting duct diameters in HVAC projects
When it may not be suitable
This component is not intended for use in environments where corrosive gases or chemical vapors are present, as these may degrade the material over time. It is also not suitable for high-pressure industrial pneumatic conveying systems that exceed the structural ratings of standard ventilation ducting.
Key specifications
Primary diameter: 125 mm
Secondary diameter: 100 mm
Material: Heat-resistant galvanized steel
Application: Hot air distribution
How to use
To install the DARCO RDS 125/100, slide the larger end into the 125 mm duct and the smaller end into the 100 mm duct. Ensure that the connection is fully seated to prevent air leakage. It is recommended to secure the joints using appropriate ventilation tape or mechanical fasteners such as self-tapping screws to ensure the reducer remains firmly in place during thermal expansion and contraction.
What to consider before purchase
Verify the diameter of your existing ductwork
Ensure the material compatibility with your specific heating system
Check for sufficient clearance in the installation area
Usage recommendations
Regularly inspect the duct connections during your seasonal maintenance routine to ensure that thermal expansion has not loosened the fasteners or seals.
