Fan Pad Location
Fan pad should be perpendicular to bin wall. Fan discharge centerline should lie on bin centerline.
Recommended thickness for pad is 4" minimum. Top surface of pad should be 2" below bin
foundation. Fans with downwind heaters require fan pad to be 48" wide and add 33" onto length (D).
IMPORTANT: Fan pad and fan must be level and smooth for proper operation. Vibration problems can
result from improper fan leveling.
