LUBRICATION INSTRUCTIONS
Most Fantech products are fitted with sealed-for-life pre-lubricated bearings which do
not require maintenance for the life of the fan.
Should your fan be fitted with grease nipples, the following instructions should be
followed:-
RECOMMENDED
LUBRICATION INTERVALS
RECOMMENDED GREASES
Wherever possible the grease used should be identical to the original. When different
greases are mixed, even if they are both suitable for the conditions, incompatibility can
occur and result in rapid bearing failure.
In the absence of specific instructions supplied with the fan the following greases
should be used. STANDARD FANS Shell Alvania R3 or compatible lithium-based grease
suitable for 130°C continuous operation. SMOKE SPILL and high temp motors must use
the grease stated on the motor to maintain the Smoke Spill approval.
PROCEDURE
If the grease lines are not extended to the outside of the case the fan must be
electrically isolated for safety before work commences.
Clean the grease nipples with a clean cloth.
Introduce the new grease to all points while the fan is rotating until the old grease is
purged from the grease relief port normally located at the bottom of the bearing
housing. If it is required to manually rotate the impeller, the fan must be electrically
isolated to prevent accidental startup.
WARNING
INCOMPATIBLE GREASE, EXCESSIVE GREASE OR INCORRECT GREASE RELIEF
CAN CAUSE DAMAGE TO THE MOTOR.
