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. Air compressors take in ambient air and pressurize it to create compressed air.
You may have come across various situations in your daily life that find the use of an air compressor. The air compressor must be drained at least once in a couple of days. Water is a common by-product in the functioning of an air compressor.
Leaving an air compressor full of compressed air, or knowing whether you can or not is a regularly asked question within the air compressor community. It is perfectly safe to leave an air compressor full of pressurized air as long as the air compressor system itself has been properly maintained. In the case that the air compressor is not in use for an extended period of time then the air compressor should be drained and shut off.
I just got a 6 gallon compressor in the garage and have been dumping the air after every use. Would it be an issue leaving it pressurized all the time. Mainly used for keeping the car tires up and blowing off the work bench/tools.
Rotary screw compressor here at the shop, with another Cast Aire piston compressor backup, the disconnect is turned off every night, the building air is not dumped ever unless we are working in the system. You’ll find out the hard way when something blows in the shop and the air compressor runs all weekend. Not so worry some with the rotary screw compressor but with a piston pump you’ll come when the fire dept calls you.
We will discuss why you should drain the air from the compressor and how you can drain the air from the compressor. If you are careful and know how to properly drain the compressor of air, then you are safe to leave air in the air compressor tank. You can leave air in an air compressor, and no, there is no danger of the compressor exploding.
IF you have definite plans to use compressor next day, then would be fine to leave pressurized, but UNPLUG power. Release the air and open the drain valve for a while to let out any condensation. I have a large vertical tank compressor which I leave on all the time But, I always shut the air off at the tank so there is no pressure in the feed lines.
I would like to see the reports that you are referring to , it could help me to do a better job. I am by no way trying to discredit you or your points. I have worked with pressures up to 5,000PSI. I do realize that there is a possibility of something happening ,but again I am stressing that all the components that are in a compressed air system are designed for compressed air and not some home made cylinder ,valve,etc.
