Key Features
-
Airtight Winter Seal: Automatically closes when the cooler is not in use, preventing warm indoor air from escaping and cold outdoor drafts from entering through the ductwork.
-
Perfect SBB Compatibility: Engineered specifically to fit the 550mm x 550mm dropper duct connection size standard on the SBB800, SBB950, and SBB1200 models.
-
Energy Efficiency: Helps reduce heating costs by eliminating the “chimney effect” often found in older evaporative systems without a dedicated weather seal.
-
Automatic Operation: Integrated with the unit’s control system to open automatically when the fan starts and snap shut when the system is turned off.
-
Durable Design: Built from high-strength, UV-stabilized materials to withstand the extreme temperatures found in Australian roof cavities.
Recommended for: HVAC professionals performing a “changeover” installation or upgrading an existing Bonaire Summer Breeze unit to improve thermal performance.
