What are the characteristics of lightweight DC fans for drones?

A large company that produces drones asks us for a DC fan that is light in weight, large in air volume, and inexpensive. What are the characteristics of such a DC fan? First of all, if you want to be light in weight, it must be small in size, and the air volume will be small when the size is small. This is a problem. If the thickness of the DC fan is made thinner and the size is larger, the weight will be smaller, but the material cost will be higher. For other weights, if you want to make a fuss about the characteristics of the materials, using light materials may be more expensive, or the characteristics of the DC fan may be problematic. The lightest weight of the cooling fan manufacturer's DC fan is only 1.4g, the overall size is 15*15*4mm, and the current can be as low as 8mA. It is widely used in products that require light weight of the DC fan. Welcome to the heat dissipation classroom and news center of the cooling fan manufacturer again.
