An aeration duct apparatus for a grain bin has an air chamber with louvered side walls, which comprise a plurality of wall slats that extend the length of the chamber and slope from inner side edges thereof downward and outward to outer side edges thereof, and are spaced apart to form air gaps between adjacent slats. The slats prevent grain from flowing through the air gaps into the air chamber. In one embodiment the outer side edge of each slat is closer to a center of the air chamber than the outer side edge of an adjacent slat below, and farther from the center than the outer side edge of an adjacent slat above, such that the right and left louvered side walls each slope inward toward the center of the air chamber from lower edges thereof to upper edges thereof. The duct is well suited to hopper bottom bins.
