Answer: Follow the manufacturer’s instructions for safe shutdown procedures to avoid damage to the compressor.
Answer: It includes regular inspections, changing the lubrication water, and cleaning the air filter.
Answer: Water lubricates the screw elements, cools the compressor, and helps to maintain optimal operating conditions.
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.
A.≤0℃ B.≤-10℃ C.≤-20℃ D.≤-30℃ Answer: C Analysis: The spraying process requires a compressed air dew point of ≤-20℃ (PDP) to prevent moisture condensation from affecting the coating quality.
Answer: The biggest difference is that the GWL Series compressor does not use lubricating oil during the compression process, providing oil-free compressed air.
