Where each walk sits in the schedule
- Air compressor quarterly maintenance checklistquarterly
- Every quarter, heavier on a hard-run unit — the tank drain and the belt are where wear shows first. Run by: The mechanical or maintenance tech on the quarterly round.
- Air compressor annual maintenance checklistannual
- Once a year. The oil change and the relief-valve lift are the two things the quarterly glance never actually does. Run by: The compressor service tech on the annual service.
What most often fails on an air compressor
- Tank drain cracked open for a second and closed, so a cup of water blows out while the rest sits rusting the tank bottom.
- Belt guard left off after the last belt change because it's quicker to eyeball the belt, and it never goes back on.
- Oil topped to the top of the sight glass instead of the mark, so the pump runs overfilled and carries oil downstream.
- Relief valve never lifted because 'it's fine, it's not leaking' — it's seized and would not open on an overpressure.
- Oil changed on schedule but the wrong grade kept on the shelf, so a straight detergent oil goes into a pump that calls for compressor oil.
