GB1205PKV1-8AY - 50x50x20mm 5020 DC12V 1.5W 2-Lead Wires Centrifugal Blower Inverter / Electronics Cooling Fan
Description
Compact centrifugal (blower-style) DC fan designed for focused airflow through ducts or over heat-sinks in tight enclosures. Delivers stable pressure and directed airflow in inverter bays, control modules, networking gear, and small electronics where a standard square axial fan is not effective.

✅ Confirmed Compatibility
Please note that the following list is not exhaustive. Compatibility depends on your system’s specific configuration. It’s essential to verify compatibility with your system or enclosure manufacturer prior to installation.
✔ Inverter cabinets and VFD control bays
✔ PLC and automation control modules
✔ Embedded systems, SBC enclosures, and networking gear
✔ Projectors, 3D printers, and small equipment requiring ducted airflow
✔ Power supplies and compact electronics with 50 mm blower cutouts
☑️ Key Features
- ☑️ Centrifugal blower design for higher static pressure vs. same-size axial fans
- ☑️ 12V DC, low 1.5W draw for efficient, continuous duty
- ☑️ Long-life mag-lev bearing for reduced wear and low acoustics
- ☑️ Focused exhaust suitable for ducts, shrouds, and heat-sink channels
- ☑️ Drop-in 50 x 50 x 20 mm footprint with standard bosses
⚙️ Fit Notes
- This is a blower (side-exhaust) unit, not an axial square fan. Align the outlet with your duct or heat-sink channel; maintain clear intake on the opposite side.
- Wire convention is typically Red = +12V and Black = Ground. Always confirm your harness pinout and connector keying before power-up.
- 2-wire design provides no tach or PWM control; the blower runs at its native speed when powered.
- Ensure at least 10–15 mm clearance at the intake and a clear, low-restriction path at the exhaust to achieve the specified airflow and pressure.
