ISO 12759-5:2021 is an international standard focused on the efficiency classification of jet fans. It specifically targets jet fans with motor power between 5.5 kW and 155 kW, likely within the 500 mm to 1600 mm diameter range. This standard provides a framework for classifying the efficiency of these fans, which can be used by regulators and legislators to set energy efficiency targets, according to ISO.
