Operation parameters of fans produced for industry were checked with respect to the requirements of Directive 2009/125/EC of the European Parliament. The tests were used to determine the efficiency of fans and to compare them against values determined according to the European Directive. The test results are presented on graphs as functions of air volume flow. Those characteristics comprise distributions of total pressure, electric power absorbed by the motor, and fan efficiency. The results indicate that there is a need to develop new guidelines. They should concern those efficiencies of low-power fans which are not covered by Directive 2009/125/EC of the European Parliament. %U https://papers.itc.pw.edu.pl/index.php/JPT/article/view/884 %J Journal of Power Technologies %0 Journal Article %P 69-74%V 97 %N 1 %@ 2083-4195 %8 2017-02-27
