A. oil injection air compressor
B. oil free compressor
C. both can
D. unable to determine
Answer: B
Analysis: The semiconductor manufacturing industry has extremely high requirements for compressed air purity, so oil-free air compressors are usually selected.
Answer: “Low pressure” refers to the compressor’s ability to operate at relatively low pressure levels, making it suitable for applications that require low-pressure compressed air.
