- A. Produce lubricating oil
- B. No production of lubricating oil
- C. Need to change lubricating oil frequently
- D. high noise
Answer: B. No production of lubricating oil
Answer: “Low pressure” refers to the compressor’s ability to operate at relatively low pressure levels, making it suitable for applications that require low-pressure compressed air.
A. 50% B. 60% C. 75% D. 80% answer: C analysis: Environmentally friendly oil-free air compressors reduce oil pollution, thereby reducing the frequency of filter replacement and optimizing maintenance costs.
Answer: The isothermal compression is achieved through the use of water lubrication, which helps to dissipate heat more effectively.
A. <0.1ppm B. <0.01ppm C. <1ppm D. <10ppm Answer: B Analysis: According to ISO 8573-1:2010…
