Stationary Electric Air Compressors

How to maintain air compressors?

• Drain the tank: When your work is finished, you'll need to open the drain valve on the underside of the tank to release moisture. This needs to happen after every use, as water can corrode metal. Turn off the compressor first. When you open the drain valve, the escaping air will also push any moisture collecting around the bottom of the tank, out. Alternatively, turn the pressure regulator knob to switch off the hose's air supply and turn off the compressor. Then, wait for the pressure to leave the compressor. You can pull the pressure relief valve to release air faster, but this won't release the moisture.
• Keep an eye on the air filter: Get into the habit of checking the air filter every time you use it. Too much gunk begins to starve the motor and might cause it to fail. Replace it when you start to see a significant amount of build-up on it.
• Check oil: After you've finished storing away hoses, check the oil level again, and refill it if it has dropped too low. Once a year, you'll want to replace the oil altogether.

How long can an electric compressor run?

Depending on the size and type of compressor, air compressors can operate from a few hours up to 24 hours a day, seven days a week.
