The EF-6AUTO and EF-8AUTO Duct
Booster® fans can be installed in less than 10
minutes and automatically operate in sequence with
your furnace or air conditioner. Both units feature
a pressure control which automatically activates the
fan based on the airflow created when a furnace or
central air conditioner blower turns on. The fan then runs checking to see if airflow from
the furnace or air conditioner blower can still be detected
every few minutes. The fan turns off when this
airflow is no longer detected so it runs only when
there is warm or cool air to distribute. Simply
insert it into the duct run and plug it in.
