Abstract
Auxiliary ventilation is vital in mining industry, where dilution of dust and gases and removal of heat are some of the primary reasons. For this purpose the single stage axial fans are largely used in various sizes. The new energy efficient single stage axial fan (ENEF) design is based on the global concept of efficiency GEff. Increased overall efficiency of minimum 115% higher than existent fans currently in use was obtained by identifying and eliminating the "air stray losses". For a typical 45 kW fan, at the same delivered output air power required by standards, a save of 5...6 kW per fan is obtained. That means the fan performances are unchanged when the motor consumes less electric input power. For an underground gold mine that has an average of 200 units working 24/7 hours, it result an amount of 5 GWh/year energy savings. The paper presents the results of three years activity in research, design, manufacturing and patent of a new type of energy efficient axial fan "ENEF".
