Exhaust Duct SpiroFlex SX-TD80/125RWB – round outlet 80×125 mm, model SX-TD80/125RWB

SpiroFlex SX-TD80/125RWB is an exhaust duct adaptor with a round outlet measuring 80×125 mm, intended for integration into mechanical ventilation and air extraction systems. The component provides a transition between rectangular or oblong duct runs and circular terminal fittings, enabling controlled routing of exhaust airflow. Designed for use in residential and light commercial installations, the part supports standard ductwork layouts where a compact round outlet is required.

Advantages

The SX-TD80/125RWB offers a compact and precise transition that simplifies connection to round outlet fittings, reducing installation time and potential leakage points. Its geometry supports consistent airflow by minimizing abrupt changes in cross-section, and the component is compatible with commonly used ventilation ducts and accessories. The design facilitates a secure mechanical fit with round terminals and contributes to a tidy duct route in confined spaces.

Suitable for

• Adapting rectangular or oblong exhaust ducts to round outlet fittings with an 80×125 mm round interface
• Residential bathroom, kitchen, or utility room extraction systems
• Light commercial ventilation where compact round outlets are required
• Retrofit projects that require a transition piece between different duct shapes

Key specifications

• Outlet shape: round outlet designed to mate with circular terminal fittings
• Outlet dimensions: circular interface corresponding to an 80×125 mm profile
• Application: exhaust/return duct transition component for ventilation systems
• Compatibility: intended for use with standard residential and light commercial ductwork
• Installation orientation: suitable for horizontal or vertical routing depending on system layout

How to use

Position the SX-TD80/125RWB component at the junction where a transition to a round outlet is required. Ensure mating duct ends are clean and free of debris before assembly. Slide the round terminal or flexible duct over the circular outlet and secure with the appropriate clamp or connector recommended for the duct material. Where the component connects to rectangular ductwork, align the mating faces and fasten according to standard ventilation installation practices, using sealant or tape where airtightness is required. Verify that the assembled joints are secure and that airflow direction matches system design.

Usage recommendations

For best performance, use compatible clamps and airtight sealing materials at all joints, and follow local ventilation codes and manufacturer guidance for mounting and support. Inspect connections after initial operation and periodically during maintenance to confirm continued integrity and leak-free operation.
