Rotary screw air compressors are known for their reliability and longevity. With proper care, an oil-flooded rotary screw air compressor can last up to 60,000 - 80,000 operating hours–or nearly ten years of continuous use–before requiring a rebuild. That’s 3 to 5 times as long as a piston-style air compressor. At that point, a rebuild of the air end is likely to be needed. (Note that oil-free rotary screw air compressors have a shorter service life due to the increased wear on the rotors.)
To extend the lifespan of your rotary screw air compressor, be sure to perform all required maintenance activities. For oil-flooded rotary screw compressors, the most critical thing is to ensure that they do not run low on oil. If the oil runs low, or loses its lubricating capabilities, severe damage to the air end can occur. Be sure to check oil levels frequently and change oil on the schedule recommended by your operating manual to prevent problems like varnish that can damage the rotors.
