What does the air compressor level 0 mean without oil

"Air compressor 0 oil-free" is a professional term, mainly refers to the air quality standards compressed by the air compressor. Here "level 0" and "no oil" are two key concepts. I will explain these two words separately and give the overall meaning.

Definition of Level 0:

in the specification GB/T 13277.1-2008 "Compressed air part 1: pollutant purification level", the oil content is divided into 5 levels. Level 0 is usually a custom standard that is more stringent than the highest level defined in the standard. It refers to the fact that the total oil content in compressed air is extremely low, and may even be lower than the minimum oil content specified in the standard. This level is usually specified by the equipment user or the equipment provider for the purpose of controlling the quality of the product.

Meaning of "oil-free:

"Oil-free" means that the oil content in the compressed air is extremely low, reaching a level that can be considered "oil-free. In GB/T 13277.1-2008 standard, the total oil content ≤ 0.01 mg/m & sup3; standard oil-free compressed air is truly oil-free compressed air. Thus, "oil-free" means that the oil content in the compressed air is less than or equal to this standard.

To sum up, "air compressor 0 oil-free" can be understood as the compressed air produced by the air compressor has reached a very high purity standard, and the oil content is very low, and may even be lower than the minimum limit specified by the national standard. Such compressed air is essential in many industries with high air quality requirements, such as pharmaceuticals, biotechnology, food and beverage, etc. In these industries, the use of "grade 0 oil-free" compressed air can effectively avoid product pollution and ensure the safety of the production process and product quality.
