The AirFlow Breeze Ultra is a register vent booster fan with remote control. It is a quieter and more powerful version of the original AirFlow Breeze, says the company. By using a built-in temperature sensor, the register booster fan quietly delivers warm or cool air to any area of the home that is consistently too hot or too cold. In its role as a register booster fan, the unit is easy to install in underperforming registers - in 6- by 10-inch and 6- by 12-inch sizes - to boost their performance and solve the situation of problem rooms, where temperatures typically do not match thermostat settings. In special installations, the unit can also assist in moving air up, down, from room to room or level to level. In its role as an air mover, the AirFlow Breeze Ultra may be installed in a wide variety of ways, utilizing the stud wall cavity as a passageway to move air. Controlled by a three-speed fan setting, the unit offers airflow rates up to 150 cfm. The register vent booster fan has adjustable fan speeds, uses long-life brushless dc fans, is controlled by a thermostat and, when set, automatically turns on and off.
