AIRSOLVER® is a fan selection tool your Brock dealer can use to help determine the appropriate size and fan type for your proposed bin diameter, eave height and grain type. The software includes choices from Brock’s axial, centrifugal, centrifugal in-line and double-inlet fans for the desired type of grain conditioning.  Photos show typical results for a 48 ft. (14.6 m) and 90 ft. (27.4 m) diameter bin calculated air flow and static pressure.
