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.
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.
Answer: Yes, the GWL Series compressor adopts an efficient cooling system and can operate normally in high-temperature environments.
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.
