KA1238HA2BML/FS KAKU 230V 120mm AC Fan with Failure Alarm

Description

The KAKU KA1238HA2BML/FS is a high-performance 230 V industrial AC axial fan with dimensions of 120 x 120 x 38 mm, integrated with the FS120B/C Failure Alarm system. This unit is purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths while providing real-time monitoring of fan operation. It features a heavy-duty shaded-pole motor capable of sustaining a 21 W power input (at 50 Hz) or 18 W (at 60 Hz) to drive its specialized high-velocity impeller at speeds of 2700 RPM or 3100 RPM respectively. Engineered specifically for air displacement in mission-critical hardware environments, it utilizes a 38 mm deep die-cast aluminum housing and the FS120B/C electronic alarm module to provide balanced pressure and immediate notification of rotation failure. The mechanical design relies on precision maintenance-free ball bearings and a black-painted frame to ensure reliable continuous operation across an ambient temperature range of -20 °C to 70 °C. Featuring a robust lead wire interface and thermal impedance protection, this fan is a critical component for industrial control cabinets, server racks, and high-security power systems where long-term reliability and active status monitoring are mandatory.
