Air Compressor – How to Store Filled Compressor Without Water Damage

air-compressor

I'd like to keep my air compressor filled for quick tire top-offs, like at gas stations. The manual says to empty the tank after 4 hours. How do gas stations avoid draining this often? Is it possible with a consumer compressor?

Best Answer

Automatic blowdowns

This taps the bottom of the tank where water would accumulate. At intervals, it blows some air out of the tank. PSHHHHHT! This ejects most of the water and some air.

This operates at time intervals, when the compressor cycles on or off, or when water is detected.

Your electric bill will not like this

In real world practice, compressors are not leakproof. It will cycle randomly at all hours.
