💡 What stops a standard air compressor from maintaining rated PSI over time?

Dropped pressure usually stems from busted seal faces or loose terminal screws dragging current away from the motor windings.
- Grip power lugs tight so resistance doesnt build up near the relay contacts when she gets heavy workloads.
- Peek inside the rubber bellows for sneaky pinholes leaking air while the tank sits cooling down outside.
- Pull the old micro switch before fried metal tabs stick together and quit snapping back on command.
