Magnetic suspension blower for tight airflow paths

This 4520 frame magnetic suspension blower runs at 12 V and draws 1.2 W, delivering focused airflow through a compact centrifugal design. It suits projectors, small-form-factor chassis and industrial enclosures where directional cooling is needed in restricted spaces. The magnetic suspension bearing reduces friction and noise during continuous operation. Supplied as a pack of five identical units.

Sustained load behaviour with magnetic suspension

Under continuous duty the magnetic suspension maintains stable rotation without the wear that degrades sleeve or ball bearings over time. Power draw stays at the rated 1.2 W, so thermal output remains predictable in sealed housings. The blower wheel keeps static pressure consistent across long runs, avoiding the airflow decay common in axial fans at higher back-pressure. No lubrication maintenance is required for the bearing system.

Questions about this item

How much noise and heat does the 12 V 1.2 W blower produce when running continuously?

The fan draws 1.2 W at 12 V and uses magnetic-suspension bearings, which typically run quieter and cooler than sleeve or ball-bearing blowers of the same rating.

What connector or voltage source must I already have to power the GB1245PKVX-8?

It requires a standard 12 V DC supply — such as a 4-pin PWM header, 3-pin fan header or dedicated 12 V molex adapter — capable of delivering at least 1.2 W.
