SXDOOL DLF12025B28L 120 mm 28 V case fan

120 mm 28 V double-ball case fan

The SXDOOL DLF12025B28L is a 120 mm square frame fan rated for DC 28 V operation. It draws a measured 0.15 A and consumes 4.8 W while spinning at 2450 rpm. The double-ball bearing is designed for continuous duty in power amplifiers, stage lighting rigs and similar industrial equipment. Builders needing a standard 12 V or 5 V case fan should look elsewhere.

Sustained 2450 rpm airflow

Under continuous load the fan holds its rated 2450 rpm without the speed decay common to sleeve bearings. The double-ball design resists dust ingress and maintains consistent torque over long operating periods. Power draw remains stable at the measured 0.15 A, so thermal output stays predictable inside enclosed amplifier chassis. No PWM or speed-control circuitry is present, so the fan runs at full speed whenever voltage is applied.

Two-wire 22 cm leads install in tight cavities

The fan ships with a two-wire cable 22 cm long, allowing direct soldering or crimp connection to a 28 V supply rail. Mounting uses the standard 120 mm hole pattern, but the 25 mm thickness must clear adjacent components in compact enclosures. Polarity reversal will not spin the motor, so verify wiring before applying power. The lack of a third tachometer wire means the host system cannot monitor fan health automatically.
