The company designed the cooling and heating bladeless fan project for customers. The design direction is to show the sense of science and technology in a simple atmosphere. The combination and matching of simple geometric shapes and the streamlined body with good coordination make it stable and low-key in any environment. Gentle wind, cold and warm, fade the summer heat, drive away the winter cold. Release ecological negative ions and clean the air. The leafless design, the base makes wind, the fuselage makes wind, and the fan blades are not exposed, reducing potential safety hazards.
