Answer: By adopting water lubrication technology, it avoids oil contamination of compressed air and uses an efficient oil-air separation system to ensure the purity of compressed air.
A. General Certification B. Medical certification C. Industrial certification D. No certification required answer: B. Medical certification
A. Pressure and temperature B. Oil quantity and pressure C. Temperature and oil quantity D. The answer cannot be determined: A Analysis: The control system of an oil-free air compressor is mainly used to monitor and control the operating parameters of the compressor, such as pressure and temperature.
A. Lower B. Higher C. Same as oilless air compressor D. The answer cannot be determined: B Analysis: The lubricating oil from the oil-injected air compressor will be partially mixed into the compressed air, resulting in a high oil content in the compressed air.
Answer: The main features include energy efficiency, low pressure operation, oil-free water lubrication, and high reliability.
Answer: The noise level is relatively low, typically below [Z] dB(A).
