KA1225-3000D24B KAKU 24V 0.29A 120x120x25mm DC Axial Fan

Description

The KAKU KA1225-3000D24B is a high-performance 24 V industrial axial fan with dimensions of 120 x 120 x 25 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty brushless DC motor capable of sustaining a 6.96 W power input to drive its specialized high-velocity impeller at a consistent 3000 RPM. Engineered specifically for air displacement in standard-profile enclosures, it utilizes a 25 mm housing to provide superior static pressure for localized hot-spot cooling in mission-critical hardware. The mechanical design relies on precision maintenance-free ball bearings and a fiberglass-reinforced PBT housing to ensure stable operation in demanding industrial environments. Featuring a robust 2-wire electrical interface for direct power connection, this fan is a critical component for industrial control cabinets, telecommunications racks, and high-capacity power supplies where reliability and standard form-factor compatibility are mandatory.
