The Ubbink Air Excellent AE55SC Semi-Rigid Duct is a high-performance rectangular ventilation duct designed for modern mechanical ventilation and MVHR systems. Supplied as a 20-metre roll, this semi-rigid plastic duct measures 130 × 60mm and is manufactured with integrated anti-microbial and anti-static additives to help maintain clean, hygienic airflow throughout the system.

Designed as part of the Air Excellent ducting range, the AE55SC duct is compatible with modular manifolds and can be used alongside all six Air Excellent duct types. Its semi-rigid construction allows it to bend easily around obstacles while retaining its shape, making installation quick, tidy, and efficient.

The duct’s radial internal design ensures low system pressure loss, while airtight mechanical connections deliver excellent airtightness performance (Class ATC2 up to ±1000 Pa). This helps minimise fan energy consumption and reduce sound production, contributing to a quieter and more energy-efficient ventilation system.
