TKFAN's smallest size fan is 15x15x4mm axial fan, TKFAN's smallest size blower is 18x18x4mm blower (2017). Throughout the industry, the smallest size fan is 9x9x3mm made by Taiwan SUNON, the size is only as small as a thumb. Silent fans are widely used in household appliances, car navigation, headlights, portable handheld devices, etc. Since these devices tend to be used in quiet environments, these fans must be quiet and have sufficient airflow. It is generally believed that this problem can be solved from three directions. By changing the structure of the impeller, the air flow can be guaranteed and the noise can be reduced. An important example is that the German EBM company has produced a special low-noise fan based on the principle of owl feathers for building ventilation; secondly, we can use a sine wave circuit to drive Reduce electromagnetic noise. Third, use special bearings. A few years ago, TKFAN has begun to try to use ceramic bearings, pure copper oil-impregnated bearings, special plastic bearings, all kinds of bearings are used in special fields, and have gradually achieved some success. I hope we can do well in this regard better future. Waterproof fans are used in some special fields. Such as heat dissipation of marine cruise lights, high-power LED lights, outdoor household humidifiers, industrial humidifiers, etc. General parts are IP55 moisture-proof and IP68 waterproof and waterproof. IP68 waterproof is generally divided into nano-coating process and epoxy resin sealing process. For details, please refer to the introduction of our company's waterproof fan. We have a large air volume/pressure test system, and a 16db background noise test room. These test systems can be used for your final product testing and are free of charge.
