MAINTENANCE

MAINTENANCE ITEMS AND MAINTENANCE PERIODS

Bendpak Rotary Screw Compressors require regular

maintenance. Regular maintenance will provide long

Compressor component life and long term trouble free

operation.

1. Bleed off any internal pressure by pulling open

pressure relief valve located on the left side of the Oil

Separation Filter. (See Fig. 12.1 )

2. Confirm the pressure has been bled off by reading

Pressure on oil Separation Tank. (See Fig.12.2 )

MAINTENANCE SCHEDULES

Check the running temperature and working pressure.

(Daily)

Record the current, voltage, temperature and pressure.

(Daily)

Clean compressor only after stopping (Weekly)

Blow the air filter with compressed air. (Weekly

Check oil level (Monthly)

Check the bolts on the belt pulley( Shaft coupling) Only

after compressor is stopped and the power is locked out.)

Blow the cooler with compressed air.

*Please see pages 32 -33 for more detailed information.

ATTENTION:

Reduce the Maintenance intervals in severe operating

environments or severe demand applications.

First 500 operating hours (first Maintenance)

Check the quality of oil. The oil may be reused after

being filtered cleanly. Otherwise, replace it.

Replace the oil filter.

Replace the intake filter.

Replace the oil separation filter.

Check the wear of belt pulley and the alignment of

the motor and Air End pulleys.

Every 2000 Hours

Replace the oil filter.

Replace the intake filter.

Replace the oil separation filter.

Check the wear of belt pulley and the alignment of

the motor and Air End pulleys.

Check intake-control valve.

DO NOT PERFORM ANY MAINTENANCE OR

INSTALLATION OF ANY COMPONENTS

WITHOUT FIRST ENSURING THAT ELECTRICAL

POWER HAS BEEN DISCONNECTED AT

THE SOURCE OR PANEL AND CANNOT BE

RE-ENERGIZED UNTIL ALL

MAINTENANCE AND/OR INSTALLATION

PROCEDURES ARE COMPLETED.

DO NOT PERFORM ANY MAINTENANCE OR

INSTALLATION OF ANY COMPONENTS

WITHOUT FIRST ENSURING THAT ALL INTERNAL

PRESSURE HAS BEEN RELIEVED FROM THE

SYSTEM. ISOLATE THE COMPRESSOR FROM

THE AIR SUPPLY LINE /AIR TANK WITH USE

OF SHUT OFF VALVES.

Fig. 12.2

DANGER

SERVICING WHILE

PRESSURIZED CAN

CAUSE SEVERE INJURY.
LOCK OUT SOURCE AND

RELIEVE PRESSURE

BEFORE SERVICING.
