Technical Description

300mm axial fan is primarily used in data centers and the telecommunications industry. In data centers, air-cooled cabinets, server racks, and IDC rooms often require cabinet fans for forced cooling and air circulation. This 24vdc axial fan is designed for direct installation and is compatible with DC power supplies, eliminating the need for additional voltage conversion and simplifying installation. It also provides reliable cooling for telecommunications base stations, 5G equipment cabinets, power distribution cabinets, and UPS cabinets. It is also commonly found in energy storage applications. Energy storage cabinets, photovoltaic inverters, and SVG reactive power compensation units contain high-power components that generate significant heat, requiring axial cooling fans for continuous heat dissipation. It is also used in industrial automation, such as in variable frequency drive cabinets, PLC control cabinets, and high- and low-voltage power distribution cabinets. The external rotor design offers high efficiency, low noise, and a compact footprint, making it easy to install in various cabinets without taking up excessive space.
