Air is introduced under plenum fitted horizontally across the bottom of the silo. When the silo is full, underneath the plenum is open airspace. The air is forced down then up the cone, spreading to the walls for even distribution through the silo. The same plenum is suitable for all cone bottom silos. 3M (10ft) diameter to 9M (30ft).
