I-Beam Angle Iron
If the fan is mounted at the same level
or higher than the diffuser, the winglets
must be at a distance that is at least 1x
the measure of the fan’s diameter.
If the fan is mounted below the diffuser,
the winglets must be at a distance that
is at least 2x the measure of the fan’s
diameter.
