The short answer is yes, it is perfectly safe to leave an air compressor full. ... So while under regular duty cycles, a full air compressor is standard, but during extended non-use, an air compressor should be drained and deactivated.

Should you empty air compressor after every use?

Yes, definitely drain it after each use. Need to avoid letting water pool in the tank, possibly corroding and weakening it. Release the air and open the drain valve for a while to let out any condensation. If you open drain valves too quickly moisture that settles to the bottom of the tank gets dispersed.

When should I drain my air compressor?

It is recommended that you drain your tank daily, whether it is manually or automatically. Water build up in your tank can cause the bottom of your tank to rust forcing you to invest in a new tank. If you find yourself forget about draining your tank, you should look into purchasing an electronic drain valve.
