  • 50-piece pack suits batch builds or spares

50-piece 12 V turbo blower kit

This pack contains fifty new GB1245PKV1-8AY turbo blower fans measuring 45 by 45 by 20 millimetres. Each unit runs on 12 volts and draws 0.5 watts. The blowers suit compact enclosures, industrial chassis or appliance cooling where focused airflow is required. Buyers needing larger axial fans or PWM speed control should look elsewhere.

Simple two-wire installation

Connect the red and black leads to a 12 volt source; no separate controller or header is needed. The small frame fits tight cut-outs but leaves little margin for misaligned screw holes. Vibration can appear if the mounting surface is uneven, so use all four fixing points and check clearance against nearby components before powering on.

Questions about this item

How can I confirm the GB1245PKV1-8AY turbo blower is spinning at the correct 12 V after installation?

Connect the fan to a 12 V header and verify the rotor spins smoothly; the 0.5 W rating means it should draw very little current while running.

What comes in the package and what extra parts are needed to mount the 45×45×20 mm fans?

The box contains 50 new GB1245PKV1-8AY 4520 blowers; you must supply mounting screws and a 12 V power connection for each unit.
