Static-pressure compensation allows a concealed unit to adjust its fan speed automatically based on the resistance of the ductwork. This is a premium feature in our Slim Duct Multi-Zone collection for consistent airflow. When you pair a Bravo Milano 12,000 BTU with a ducted head in a Multi-Zone setup, the system balances both rooms perfectly. To ensure the blower motor isn't overworking, always use the high-flow registers found in our Accessories section. A level Wall Bracket for the outdoor unit ensures that no vibration affects the sensitive pressure sensors. This compensation is what allows our concealed systems to outperform traditional "one size fits all" central air units. It ensures that every room gets the exact amount of air it was designed to receive.
