AD1224MB-F99GP ADDA 24V 0.68A 120mm DC Axial Fan

Description

The ADDA AD1224MB-F99GP is an ultra-high-performance industrial DC Axial Fan with dimensions of 120 x 120 x 38 mm. Driven by a high-torque Brushless DC Motor, this 1224 series model is specifically engineered for heavy-duty thermal management, operating on a nominal 24 VDC. It delivers a powerful maximum airflow of 162 CFM (275.2 m³/h) at a high rated speed of 3800 RPM. With a rated current of 0.68 A and a power input of 16.32 W, it is designed to provide the intense static pressure (0.57 inAq) required to push air through high-resistance industrial systems. This model features a premium dual-ball bearing system and a specialized 9-blade aerodynamic impeller for maximum air displacement and stability. Equipped with a three-wire termination, the AD1224MB-F99GP includes an integrated tacho signal output for real-time speed monitoring, providing essential cooling for high-capacity industrial inverters, large server enclosures, and high-density power electronics.

Application
The AD1224MB-F99GP is primarily utilized as a specialized inverter cooling fan for high-power industrial frequency drives and large-scale solar converters, where it handles the intense thermal output of high-current IGBT modules. Its 38 mm deep frame and 9-blade high-torque impeller are essential for these applications, as they generate the 0.57 inAq of static pressure necessary to overcome the significant air resistance found in densely packed inverter cabinets with heavy-duty dust filters. Beyond power conversion, this 24V fan is a critical component in telecommunications base stations, large CNC machine centers, and high-performance industrial UPS systems. The integrated tacho signal allows for active health monitoring by the system controller, ensuring the fan maintains its 3800 RPM operation to prevent system thermal shutdown or component failure in mission-critical 24/7 industrial production environments.
