READER: Is it important to shut down and drain an air compressor each evening, and drain the water out of the tank? How does that water get in the air tank? Does it make the inside of the tank rust? Is an air compressor dangerous?

STEVE: Yes, it is very important to service an air compressor regularly, meaning there is no set time.

The reason there is such a loose time frame for servicing is because all climates are different as far as humidity, and compressed air comes from atmospheric air, which contains humidity. This compression creates water in the tank. Therefore, water drainage of air compressors is directly related to the area in which you live.

Some manufacturers suggest draining daily to ensure less rust is formed in the tank. In some areas, each week is sufficient. I suggest draining the tank each week, watching for collected amounts of water drained, and scheduling a drain, as needed.

An air compressor can be a very dangerous tool. Explosions, usually caused by rusty tanks, are rare, but when they occur, bodily and structural damage can result.
