Non-electric Fresh Air vents

rockies63 | Posted in Mechanicals on

I am considering using the Lunos type of ventilation fans which seem to require electricity all the time in order to work. Has anyone used these non-electric ventilation devices?

    Aren't these make-up air intakes?

    Scott,
    These devices are basically a hole in the wall. You can achieve the same effect by cracking a window open.

    A makeup air vent (a hole in the wall) is designed to allow outdoor air to enter a house that has been depressurized by an exhaust fan. They usually don't work as intended, because they are overwhelmed by the stack effect and wind.
