The Fresh In supply fan ventilation system brings fresh air in from the outside—but only when it makes sense to do so. The fan’s technology continually monitors the outdoor temperature and humidity levels and estimates the best time of day to run the fan. Fresh In features an ultra-efficient, variable-speed motor that allows the fan to deliver constant airflow without losing efficiency. The unit can easily be installed between ceiling joists with its flush-to-ceiling mount design using Broan’s decorative finish ring, and filters can be replaced in less than 30 seconds, according to the company.
