The induced ejector fan uses the characteristics of high-speed jet in aerodynamics to induce and stir a large amount of surrounding air by spraying out high-speed air with bright kinetic energy, and takes it to a specific target direction. The center speed of the jet gradually decreases from the nozzle exit point, but the width of the jet gradually increases, and the induced surrounding air also gradually increases. On the one hand, the indoor harmful gas is diluted, and on the other hand, the indoor air flow is driven, and the harmful gas is concentrated and quickly traveled along the preset air flow path to the exhaust fan, which is discharged by the exhaust fan, so that the large indoor occasions have a good ventilation effect.

The application of induced ejector fans can effectively reduce the concentration of harmful gases in large indoor places, maintain good air, and improve the indoor environment.

Large places such as subway car auxiliary sections, underground parking lots, underground supermarkets, warehouses, industrial plants, stadiums, and large areas with local pollution induced ventilation.
