## Long description

SpiroFlex SpiroFlex 60/100‑80/125 IMK (collar) white is a stepped duct adapter designed to connect two standard circular duct sizes in ventilation and HVAC installations. The adapter provides a compact, collar-type mechanical transition between a combined 60/100 mm spigot and an 80/125 mm spigot, enabling reliable airflow routing where a change of duct diameter is required. Its white finish is suitable for visible installations and helps maintain a clean appearance in service spaces.
Advantages
The SpiroFlex IMK collar adapter offers a simple, space-efficient solution for joining round ducts with different nominal diameters. It creates a secure mechanical connection without the need for complex fittings or extensive on-site fabrication. The stepped design ensures correct alignment of ducts and reduces turbulence at the transition point, while the collar-style connection facilitates straightforward assembly and disassembly during maintenance.
Suitable for
Joining ventilation ducts where a transition between 60/100 mm and 80/125 mm circular sizes is required
Domestic and light commercial HVAC systems with round ductwork
Retrofit projects where existing duct runs must be adapted to different fan or register connections
Applications needing a compact collar-type mechanical connection for air distribution or extraction
Key specifications
Stepped connection: one end fits 60/100 mm combined spigot, other end fits 80/125 mm spigot
Type: collar (kolanowy) adapter for mechanical duct joining
Shape: circular/stepped transition for round ducts
Finish: white surface suitable for visible installations
Material characteristics: designed for standard ventilation use (mechanical stability for air distribution)
How to use
Install the adapter by aligning each stepped end with the corresponding duct spigot, sliding the collar over the mating profiles until fully engaged. Secure the connection using appropriate clamps, screws, or sealing clips as required by the duct system and local practice. Ensure joints are sealed or taped where necessary to maintain designed airflow and reduce leakage. For best results, confirm inlet and outlet diameters match the adapter dimensions before final assembly.
Usage recommendations
Use the adapter in dry, indoor ductwork environments and avoid exposure to corrosive agents or direct weathering. When installing in systems with significant airflow or pressure differentials, verify connection tightness and consider additional sealing to minimise leakage. Follow applicable ventilation installation standards and local codes during fitting and maintenance.
