What is the main purpose of the water-lubricated design of oilless air compressors?

Answer: The main features include energy efficiency, low pressure, oil-free operation, and water lubrication, providing pure compressed air suitable for industries with high air quality requirements.

A. Annex B B. Annex C C. Annex D D. Annex E Answer: C Analysis: The gas production standard corresponds to ISO 1217 Annex D.

A. Traditional models are more stable B. Environmentally friendly models are more stable C. Both have the same stability. Unable to compare the answer: B Analysis: Environmentally friendly oil-free air compressor adopts adsorption drying technology, and its dew point stability is-20℃±2℃,…

Answer: The main features include energy efficiency, low pressure operation, oil-free water lubrication, and high reliability.

A. Higher B. Lower C. Same as oil injection air compressor D. The answer cannot be determined: B Analysis: Oil-free air compressors do not need to replace lubricants and oil filters, so the maintenance cost is low.
