Periodically drain the air totally my compressor and let the open valve to the cylinder can breathe. Sounds good to me leave it for a few hours (at night) without pressure.

( the compressor not shutting off and a rusty tank) .

Jere nice addition, electrical system must be observed.
I believe that a safety switch with a very close thermal relay motor capacity (amps) will help in case of failures in general.

Today the Relay SSR with ultra quick fuses are also a good option.
