GB 19153-2003 is an important standard on the energy efficiency of volumetric air compressors. It clearly sets the energy efficiency limit value of this type of compressor, which is the basic threshold for market entry. Products that do not meet this value are prohibited from being sold. At the same time, energy-saving evaluation values are given to provide a basis for evaluating energy-saving products. By standardizing energy efficiency, guide enterprises to improve technology and optimize product design, promote the research and development and promotion of energy-saving volumetric air compressors, help the industrial field reduce energy consumption, and promote green and sustainable development of the industry, which is of great significance to improving energy efficiency.
