Gatco - Hopper Bottom Bins

The GrainAir Tube system is also set up to work well in your hopper bottom bins. The square tubing cross brace runs across the hopper bottom and supports a magnetic base for the GrainAir Tube. This base helps support the GrainAir Tube and roof ring during unload and acts as a shear pin as the last of your grain empties from the hopper, preventing damage to the GrainAir Tube.
