Effective Maintenance

• Check the inlet and discharge valves for sticking due to carbon deposits.
• Check for excessive air through the crank case breather indicating worn piston rings.
• Check for low oil pressure indicating worn bearings.

Recommended Rebuild: 5,000-10,000 hours

Rotary Screw Airend

• Check for mechanical seal leakage.
• Check for inlet valve wear.
• Check for excessive bearing "play."

Recommended Rebuild: 50,000 - 100,000 hours

Motor

• Grease motor bearings with the right type of grease.
• Replace bearings on a conservative schedule.
• Check amp draw to prevent motor overload.
• Ventilate compressor room and limit ambient temperature to increase motor life.

Drive Train

Direct Drive (without permanent alignment components)

• Verify that the direct drive system is perfectly aligned.
• Check frame and mounting block for "settling" which may cause misalignment and coupling damage.

Direct Drive (with permanent alignment components)

• Check coupling annually.

Gear

• Check spray bar for excessive contaminants and plugged orifices.
• Check for wear and "backlash."
• Ensure proper lubrication.

V-Belts

• Check v-belt tension.
• Check wear on v-belt/pulley.

Lubricants

Lubricants cool, seal, lubricate and remove contaminants from a compressor.

• Use proper grade (see manual).
• Drain existing lubricant before refilling.
• Draw routine lubricant samples to determine maximum lubricant life.
• Use synthetic lubricant for maximum service life.

Filters

Air

Any contaminants not trapped in the filter will eventually damage machinery and equipment.

• Use proper micron rating as specified by OEM.
• Check pressure differential and, if necessary, carefully clean according to manufacturer's recommendations.
• Check for worn/damaged seals.
• Check structural integrity.
• Replace after filter has been cleaned two or three times.

Lubricant Filter/Lubricant Separator

• Use only genuine replacement parts.
• Change when maximum pressure differential is reached or at each lubricant change, whichever occurs first.

Coolers

• Check for visible contamination and clean regularly.
• Keep clean and dry.
