  1. Oil-free piston air compressors typically last around 10-15 years, while oil-free rotary screw compressors tend to last around 20-30 years. You can generally expect anywhere from 2,000 to 8,000 hours of service. However, the lifespan depends largely on maintenance, proper care, and usage habits. A common criticism of oil-free compressors is ...

  2. Oct 19, 2021 · If there is no great need for an oil free air compressor, such as where air contamination needs to be avoided, an oil lubricated compressor is a more economical option. Oil free air compressors are lighter which makes them an ideal option for applications where portability is required or needed for compressed air is less such as within the medical sector.

  3. Jan 23, 2023 · An oil-free compressor’s air-end typically lasts around 50,000 hours, while an oiled compressor’s air-end can last up to 150,000 hours or more. This is because the lubrication provided by the oil helps to reduce friction and wear on the internal components, increasing the overall lifespan of the compressor.

    • Oil free compressors provide contaminant free air. False! While oil free compressors reduce the amount of oil that needs to be removed from compressed air, there are many contaminants found in atmospheric air and throughout the entire system.
    • The air compressor is solely responsible for contamination in the compressed air system. False! Contamination in a compressed air system comes from four different sources
    • Oil free compressors do not use oil. False! The biggest myth is that oil free compressors do not use oil. Oil free compressors do not use oil in the compression chamber, so oil doesn’t contact the air being compressed.
    • Oil free compressors are more expensive. Up for debate! So, oil free compressors do have a higher initial capital cost than oil lubricated alternatives, by up to 40-50%.
  4. How often you perform these tasks will depend on the manufacturer’s recommended service schedule, but you can count on doing a fair bit more maintenance on an oil-lubed compressor than you would on an oil-free model. Oil-Free Air Compressors. Make no mistake, there are still maintenance tasks to perform on an oil-free compressor (changing the ...

  5. Nov 25, 2021 · With an oil free air compressor, you do not need to worry about any of this and the lack of oil can make it a cheaper option over the long term. Lighter Oil free air compressors have fewer parts inside so they weigh less than regular air compressors, making them a great choice for small to medium sized applications. Lower costs Thanks to their ...

  7. These methods minimise friction and ensure that the compressed air remains free from oil contamination. Atlas Copco’s ZR/ZT55-VSD oil-free compressor, for instance, is available in water- or air-cooled versions and operates at a maximum working pressure of 8 bar (125 psi), with a motor power of 55 kW (75 hp).
