VIBRATION ISOLATOR INSTALLATION

 Choose proper isolator
(Isolator can be selected from Kruger selection programme)

Adjust deflection based on the selected isolator.
 Maintain the operating / free height at the same level through step 2.
(The entire assembly must be levelled)
 Check all the deflection and operating / free height is properly maintained.

ROUTINE MAINTENANCE

Maintenance should always be performed by experienced and trained personnel. Do not attempt any
maintenance on a fan unless the electrical supply has been locked out or tagged out and the impeller has
been secured.
Under normal circumstances, handling clean air, the system should require cleaning only about a Year.
However, the fan and system should be checked at regular intervals to detect any unusual accumulation.
The fan impeller should be specially checked for build-up of material or dirt which may cause an Imbalance
with resulting undue wear on bearings and belt drives. A regular maintenance program should be
established as needed to prevent material build-up.
Periodic inspection of the rotating assembly must be made to detect any indication of weakening of the rotor
because of corrosion, erosion, or metal fatigue.
