AC case fan for 110 V systems

The SJ1238HA1 is an axial blade fan designed for 110 V AC mains operation. It fits standard 120 mm by 120 mm mounting holes with a 38 mm thickness. This unit is suited for chassis ventilation in equipment that runs directly from line voltage.

Thermals, noise and power draw

As an AC-powered axial fan, it moves air continuously while connected to 110 V supply. Noise level and power consumption are determined by the motor design and blade profile at rated voltage. Thermal performance scales with the airflow produced across the 1238 frame.

Questions about this item

How is the 110 V AC fan installed and what wiring mistake should be avoided?

Mount the 120 x 120 x 38 mm frame using the four corner holes, then connect the two lead wires directly to a 110 V AC supply; the common error is reversing line and neutral, which can prevent the motor from starting.

What maintenance will the SJ1238HA1 axial fan need over time?

Periodically clean dust from the blades and ventilation slots with compressed air; the sleeve-bearing motor is not user-serviceable, so plan to replace the entire 1238 unit when noise or airflow drops noticeably.
