Taiwan KAKU AC Case Fan

The Taiwan KAKU KA1725HA2B is an AC-powered case fan built for 220–240 V mains supply. It targets industrial and server builders who need direct mains operation without a separate power supply. The 172 × 150 × 51 mm frame fits standard mounting points for equipment enclosures.

Double Ball Bearing and Airflow

Double ball bearings support continuous duty at 2700–3100 rpm, delivering 5.37–6.88 m³/min of airflow. The bearing choice reduces wear in 24/7 environments such as medical, rail or industrial cabinets. Noise reaches 56–61 dB-A, a trade-off for the high static pressure needed in dense chassis.

Mains Wiring and Clearance

Installation requires wiring the fan directly to 220–240 V AC at 50/60 Hz, drawing 1.578 A and 35–38 W. Builders without mains-rated wiring experience should use a qualified electrician. The 51 mm depth and 950 g weight demand secure mounting and clearance verification before power-up.

Questions about this item

Will the double ball bearing need replacement, and how long does it typically last?

The double ball bearing is rated for continuous operation at 2700–3100 RPM and 50–60 Hz; bearing life depends on ambient temperature and duty cycle, but ball bearings generally outlast sleeve types in 220–240 V AC fans.

What thermal or airflow limit appears first during non-stop use?

At 38 W / 35 W the fan moves 5.37–6.88 m³/min; sustained load is limited by the 56–61 dB-A noise ceiling and the 950 g motor’s ability to dissipate heat inside a 172×150×51 mm frame.

How loud and hot does the 220 V AC motor get after running all day?

Expect 56–61 dB-A at 2700–3100 RPM with 38 W / 35 W draw; the 950 g aluminium frame spreads heat, but surface temperature will rise above ambient during continuous 220–240 V operation.
