Axial fans are named for the direction of the airflow they create. Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction. Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. Axial fans are a type of compressor that increases airflow pressure as it passes through. The fan blades work by forcing air to move parallel to the shaft, which the blades rotate around. Ultimately, the axial flow fan characteristics cause air to flow axially.
DC fans are fans that are powered by the direct current. Like AC Axial fans, there are DC axial fans and DC cross flow fans too. DC axial fans are widely used in the air-vent exhaust, electronic device cooling, computer ventilation, etc. A DC fan motor applies that same technology to your ceiling fan, converting the supplied AC power from your home and regulating electrical speed by controlling the current itself. This results in more efficient air movement, using less energy, and nearly silent motor operation.
The Intelligent Motion series Brushless DC Axial fans include full-wave in-board circuit designs with multiple features that create air movement “intelligence”. By using controls that are programmable, voltage fluctuations from power supplies are reduced, protection is enhanced, and optimum performance is ensured. DC axial fans are also widely used within the medical industry in a variety of medical devices to provide temperature control in a compact environment. DC fans can be found in oxygen concentrators, ventilators, diagnostic imaging equipment, and other medical devices.
