Q: How to determine the quality of an oil-free air compressor?
Answer: The quality of an oil-free air compressor depends on the cleanliness of the compressed gas and whether the oil content in the air meets the standard. This is the most basic, and then look at the overall appearance and working sound of the oil-free air compressor to see if there are any scratches or abnormal noise.
The quality of compressed gas is the most important factor in determining whether the spare parts of the entire air compressor are qualified or not, and the quality of a non oil free air compressor. No matter how well the compressed gas does not meet the standard, it is useless to promote it.
