Airtight: Patented floating ball check valve eliminates backdrafts for
greater home comfort
Noiseless: Provides virtually silent operation, even in strong winds
Secure: Grid and ball prevent animal intrusions
Insulating: Durable insulation material eliminates thermal bridge to
improve energy efficiency and prevent condensation on ducts
Lowers Heating Costs: Prevents heated air from escaping when dryer or bath
fan is not in use
The EcoVent by Broan is the only exit vent to feature the patented floating
ball check valve. This award-winning innovation improves air flow efficiency,
reduces heating costs and provides an airtight thermal seal that prevents
condensation in ducts while eliminating backdrafts to keep homes quiet and
secure even on the windiest days. With EcoVent, animals can’t get in and heated
or cooled air won’t get out. It is an attractive, easy way for homeowners to
enjoy a more comfortable, secure and energy efficient home.
