:127 Fresh Air

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:127 EcoTip: A fresh air supply is important to help prevent back-drafting (:113). Rather than leaving a vent open to the outside continually, the Cape Damper can be installed through a wall to allow air to flow in only one direction when needed but to also prevent back-drafting should a dangerous negative pressure develop.

***********************************

 Additional Information

The Cape Damper can be mounted through the wall to allow fresh air to enter, or as an exhaust damper for exhaust fans or a clothes drier. Since it doesn’t have spring loaded flaps, it won’t clog with lint, but can prevent clothes dryer back-drafting.

If it is being used for allowing fresh air to enter, it will need a screen added to help prevent insect and rodent entry.
