Air Compressor 101: How much maintenance does my air compressor require?

Air Compressor Maintenance

Essentially, there are four service milestones that need to be completed on your air compressor:

  1.  Weekly
  2. Minor (2,000 hours)
  3. Interm (4,000 hours)
  4. Major (8,000 hours)

The Weekly Service is just as it sounds, should be completed once a week. At this point you want to check all filters and oil level. Additionally you will want an ideal differential reading from sump to delivery pressure of 2 – 6 PSID. If this is greater than 8 PSID then you might have a dirty separator, the check valve might not be opening or you may have a transducer issue.

During the 2,000 Hour Service you will be submitting an oil sample, especially if your air compressor is presently under warranty. If your are running food grade oil, you will want to perform this test every 1,000 hours. Upon your sample being processed, you will receive a report back stating your oil’s TAN number, which is essentially indicates the oil life left. Additionally, if this is the first 2,000 Hour Service, you will want to check all electrical connections, as the heating and cooling of the wires may affect the tightness of the connections.

During the 4,000 Hour Service you will be removing the separator and examining and cleaning the Scavenger line. If this line gets blocked or clogged, it ill carry over oil into the air supply. In addition, you will perform all steps in both the Weekly Service as well at the 2,000 Hour Service.

During the 8,000 Hour Service you will be examining the inlet valve. Anytime you replace the inlet valve you will also be replacing the valve body, spring, check valve and the air filter.  Additionally, you will be performing all steps in the Weekly, 2,000 Hour, and 4,000 Hour Services listed above.
