Horizontal Straight Duct Tubes are an economical solution designed for hopper cones. They're ideal for conditioning and cooling grain with a limited ability to dry in larger bushel bins. These duct systems are recommended for aerating bins up to 26’ grain depth. The new design includes laser-cut internal rings providing increased strength, as well as downward facing louvers that provide improved cleanout. The Next Generation Aeration Tube is also now

available in 3', 4', 6', 7' and 8' sections that will adapt to more hopper bin diameters.
