at least 200,000 hours. All bearings shall be factory lubricated and equipped with
standard hydraulic grease fittings and lube lines extended to the motor side of the
fan. Fan drives shall be selected for a 1.5 service factor and anti-static belts shall be
furnished. All drives shall be fixed pitch. Fan shafts shall be selected to operate well
below the first critical speed and each shaft shall be factory coated after assembly
with an anti-corrosion coating.
