Answer: Perform a series of tests to check the discharge pressure, capacity, and energy efficiency, and compare the results with the manufacturer’s specifications.
Answer: It uses a water-cooled system to maintain optimal operating temperatures.
Answer: The compressor uses water instead of oil to lubricate the screw elements, eliminating the risk of oil contamination in the compressed air.
Answer: The noise level is relatively low, typically below [Z] dB(A).
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.
