Active makeup air system.Rather than using negative pressure created by the range hood to move air, an active makeup air system has its own blower to move the air. This is our go-to method for clients who hire us to do makeup air. We use theFantech makeup systembecause it includes ...
PROBLEM TO BE SOLVED: To enable the optimization of an exhaust gas flow by providing a backflow prevention damper having: an attaching portion used for attaching the backflow prevention damper to an exhaust portion; an opening/blocking portion which opens and blocks exhaust to an exhaust duct; ...
damper. If you are planning to connect the range hood through the round duct on top of the model, you'll want to connect it to a damper (to keep the hot/cold air, debris and small animals/insects out). This damper issold separately. All in all we can't blame Broan-NuTone for ...
