When creating any engineering design is necessary to identify the main function of the proposed facility. The main function of the fan is a cooling medium. Thus, the cooling function, which is carried out concentric rotation of the blades, it is first and affects the shape of the object and express imaginative solution, responsible for the functionality of the design. A well-designed mechanism is beautiful in itself and does not need to hide it without the need for transparent cover. so we can enjoy the beauty of this fan. Ego main the idea is that there is no sense of vibration of the air flow, also multiplies the air flow, directing it to the optimal trajectory continuously and uniformly.
