Features
High Energy Efficiency
The fan uses a brushless DC motor to ensure a high
energy efficiency.
Constant Air Flow
Duct length, elbows and other factors increase static
pressure and negatively impact the performance of
most ventilation fans. This fan utilizes adaptive Constant
CFM technology that monitors the static pressure in the
system and speeds up or slows down the rpm of the
motor depending upon the amount of resistance within
the ducts. The fan will perform at the rated airflow and
helps avoid potential installation issues.
Flow Selection
Fans are supplied with a flow selection switch which
can be set to 50, 80, or 110 CFM.
