    Those can be a big help!

    Outside combustion air is often needed, especially in the tight"energy efficient" homes.  People need fresh air, too, and Energy/heat recovery ventilators work for them.

    good product

     have been using this fan on my commercial jobs for years   in some cases i have 2 . some basements just dont have enough space for gravity fed ducts for combustion/fresh air    Field controls also makes a good barometric damper
