Roof Vent

Roof Vent

Removable base allows ease of installation on existing bins. Lap over design prevents moisture leakage and condensation. Mushroom shape design makes it more difficult for snow and moisture to enter the bin than with traditional goose neck designs. Vent measurements: 15" inside diameter, 18" outside diameter.

The number of vents required on a particular bin is dependent upon the amount of airflow being moved through the grain.

Roof vents Required per Bin**:

  • 3HP fan - 2
  • 5HP fan -  3
  • 7HP fan - 4
  • 10HP fan - 5 

 **Rule of thumb: 1sq. foot opening for every 1000 CFM.
