Maintenance and Inspection (continued)
● Check Valve Inspection
Stop the air compressor to inspect the check valve. If the air compressor reverse rotates for 3 seconds
or longer when it stops, the check valve is leaking and should be replaced. Contact the local Sullair
distributor for replacement.
● V-belt Inspection
Verify that there is no abnormal noise during operation.
Loose V-belts can slip creating noise and may
lead to damage to the air compressor.
※ Contact the local Sullair distributor if V-belt
adjustment is required.
● Intake Air Filter Replacement
Replace the intake air filter every 2,500 hours or every year. Failure to replace the intake air filter each
year may cause compressed air reduction, excessive temperature rise, excessive vibration and sound
and/or damage to the air compressor.
● Make sure that oil and dust do not adhere to the V-belt as they will cause slippage, excessive noise
and/or damage to the air compressor.
● Wear the proper eye or body protection when servicing the air compressor.
10, 000 Hours and/or 4 Years Maintenance and Inspection Procedures
● Rubber Hose Replacement
Replace the rubber hose every 10,000 hours or 4 years. Contact the local Sullair distributor for
replacement.
● Check valve
The seating section and valve body of the check valve will wear over time, causing a malfunction to the
check valve and damage to the air compressor.
● Ventilating Fan, Electromagnetic Contactor and V-belt.
10, 000 Hours and/or 4 Years Maintenance and Inspection Procedures･ ･ ･ ･ 122PSIG Model
Every 5, 000 Hours and/or 2 Years Maintenance and Inspection Procedures･ 145PSIG Model
Call the local Sullair distributor for these maintenance and inspection items.
During this service, replace the following parts:
(1) Tip seal
Wear of the tip seal obstructs the appropriate amount of compression and causes excessive
temperature rise, etc. It can lead to a temperature error「E.TP.」appearing on the display.
(2) Grease the scroll bearing
Over time the grease in the scroll bearing deteriorates and requires replacement. If the bearing is not
re-greased at the 10,000 or 5,000 hour service requirement, serious damage to the air compressor
may occur. If the scroll does not rotate smoothly and/or a large amount of grease leaks from the
bearing, contact the local Sullair distributor immediately.
