Minimum Energy Performance Standards for pumps, fans and air compressors worldwide
June 3, 2026
EMSA published a world map showing mandatory Minimum Energy Performance Standards for pumps, fans and air compressors in effect.
Electric motors and motor systems in industrial and infrastructure applications with pumps, fans and compressors in buildings are responsible for 53% of the world’s total electricity consumption. New and existing technologies offer the potential to reduce the energy demand of motor systems across the global economy by 20% to 30% with short payback periods.
4E’s Electric Motor Systems Platform (EMSA) raises worldwide awareness of the efficiency potential of motor systems and provides guidance and tools to exploit the energy performance of new and existing motor systems worldwide.

This report summarises the test results of EMSA’s international round robin testing programme, exchanging two commercial, packaged electric motor-driven screw compressors between three laboratories worldwide. It includes a practical guide for measuring specific energy and isentropic efficiency of packaged air compressors in line with ISO 1217:2009 and Amendment 1:2016.
