The Ubbink Air Excellent Duct Cover Caps are purpose-designed accessories used to securely seal unused connections within the Air Excellent ventilation system. They are compatible with AE34C, AE48C, and AE35SC valve and floor grille adaptors, ensuring a fully airtight and professionally finished installation.

These cover caps form part of the modular Air Excellent system and are essential for maintaining system efficiency where spare duct connections are not required. By sealing unused ports, they help prevent air leakage, reduce pressure loss, and minimise unwanted noise within the ventilation system.

Designed to work seamlessly with Air Excellent semi-rigid ducting and modular components, the caps are quick and easy to install using the system’s airtight mechanical connections, supporting fast installation and long-term reliability.
