GRAIN GUARD FANS
Conventional grain bin aeration systems only dry from the bottom up and often fall short of drying grain in the center and top half of the bin.
Grain Guard fans work better because they:
- Force air into the center
- Provide a drying front that conforms to the pile of grain
- Reduce static pressure
- Increase fan efficiency by as much as 20%
- Reduce drying time by as much as 50%
