4- COOLER CELLS OR FAN IMPELLERS ARE CLOGGED / DIRTY
Check and clean
5- INTAKE FILTER IS CLOGGED
Check and replace.
6- BELTS ARE LOOSE
Check the tension of belts. It is easy to understand that the belts is loose by looking at the
movement of belt when the compressor is running. Properly adjusted belts are not beats.
Strain the belts by checking items at “belt replacement and alignment” section or inform the
service.
Also belts may be oily. In this case when the pressure increases, the oily belts may be slip.
Highly noise is heard and smoke is observed. Clean the pulleys and replace the belts
7- THERE IS A MECHANICAL PROBLEM AT AIREND UNIT
It could be understood by noisy operation ; Inform the service
U
14- THE COMPRESSOR OPERATES NOISY THAN NORMAL
1- THE MECHANICAL CONNECTONS ARE LOOSE
Check that all mechanical connections are tightened properly (The tightness of motor, pulley
and fan connections has a big importance from the point of safety)
2- THE PULLEY ADJUSTMENT IS DEFECTED
By stopping the compressor check that the pulleys are at the same level with a jig. If the
alignment is bad readjust or inform the service
3-THERE IS A PROBLEM AT MOTOR BEARINGS
Listen to the sound of motor while the cowlings are open. If you hear a bad noise from

S
ee item 13.6. Also check the belts and replace if they are damaged
2- THERE MAY BE PROBLEM İ N THE MOTOR BEAR İ NGS

O
İ L.
This point must be taken into consideration when determining the compressor room in
sandblasting casting chemical and paint / chemical finishing facilities.
4- CONTINUOUSLY OPERATING IN HIGH AMBIENT TEMPERATURE
At the compressors that operate near the boiler rooms, generator room or at areas with
insufficient ventilation, the operating temperature adversely affects the life of separator.
