SpiroFlex adapter 60/100–80/125 with condensate drain, white

The SpiroFlex adapter 60/100–80/125 with condensate drain, white is a ventilation duct transition component designed to connect concentric or coaxial ducts of different diameters. It permits reliable joining of a 60/100 mm section to an 80/125 mm section while providing an integrated condensate drain to remove collected moisture. The white finish makes it suitable for installations where the adapter is visible and where a neutral appearance is preferred.

Advantages

This adapter ensures a secure mechanical transition between differing concentric duct sizes and reduces the need for custom fittings. The built-in condensate drain collects and evacuates moisture produced during air or flue gas flow, helping to prevent corrosion and water accumulation in the duct run. The product is designed for easy installation and offers a consistent outer appearance in white that complements visible HVAC systems.

Suitable for

• Connecting concentric or coaxial ventilation or exhaust ducts with 60/100 mm to 80/125 mm cross-sections
• Retrofit projects where duct sizes do not match
• HVAC systems requiring condensate management in exhaust or flue gas paths

Key specifications

• Transition between inner/outer duct diameters 60/100 mm and 80/125 mm
• Integrated condensate drain for moisture removal
• Concentric/coaxial connection geometry
• White finish suitable for visible installations
• Intended for use in ventilation, exhaust and flue gas ducting

How to use

Position the adapter so the matching diameters align with the existing concentric duct sections. Ensure sealing surfaces are clean and free of debris, then slide or clamp each duct onto the corresponding end according to the system's fastening method. Route the condensate drain to an appropriate collection point or drainage outlet, confirming a downward slope if required for gravity drainage. Verify connections are secure and that airflow is unobstructed before returning the system to operation.

Usage recommendations

Use compatible sealing materials and clamps recommended for concentric duct systems to maintain airtight joints. Periodically inspect the condensate drain and adjacent ducting for blockages, corrosion, or leaks, and ensure the drain outlet remains clear to prevent water build-up.
