DEX self-cleaning HEPA filter -designed for complete dust collection and ventilation in large factory workshop Principles    

Airflow Form: Stratified Air Supply

When aspirating the air, fresh air is sent into the work area directly from the lower end of the workshop column. Since the blowing air temperature is lower than the temperature of the workshop, the air will first spread to the floor surface under gravity, then flow from the bottom to the top because of subsequent airflow and the heat convection generated by the heat source in the workshop, forming the dominant flow of air movement inside the workshop, and finally be exhausted to the outside at the top of the workshop. Air stream within the whole workshop flows layeredly and forms indoor temperature gradient and concentration gradient vertically.
