GB 19153-2009 regulates the energy efficiency of volumetric air compressors. It clearly sets the energy efficiency limit value as the minimum threshold for products to enter the market, and sales below this value are prohibited. At the same time, energy efficiency grades are divided to visually reflect the energy consumption level of products, and help consumers identify energy-saving products. Through these regulations, enterprises are promoted to develop high-efficiency energy-saving technologies and optimize product design. Promote the industry to eliminate high-energy-consuming products, improve the overall energy utilization efficiency, and help the industrial field to save energy and reduce emissions, so as to achieve green and sustainable development.
