Product review (4 stars): Self Opening Vane Exhaust Air Vent for 3" Diameter Duct
As the title describes this Self Opening Vane Exhaust Air Vent for 3" Diameter Duct is a fairly rare item as most exhaust fan ducts utilize a 4" diameter duct. The eave width next to the powder room in this project would only accomodate a 3" diameter opening for this duct to run through. The Panasonic fan that was installed came with a 4" to 3" step down adapter which worked perfectly to take the exhaust air to the outside. The price from this particular dealer was extremely fair and does not merit a premium that other retailers charge for this same item.
