Description
Used product. The product shown in the photographs is a cooling assembly consisting of 4 Delta Electronics AFB0812SH axial fans, installed on a metal support structure and complete with wiring and connectors.
The photographs clearly show the original fan nameplates marked DELTA ELECTRONICS, MODEL AFB0812SH, DC12V, and 0.51A. These are therefore four identical fans from the AFB series, with brushless DC motors, axial configuration, and ball bearings. The published characteristics for the AFB0812SH confirm the 80 × 80 × 25.4 mm format, approximately 4,000 rpm, 46.6 CFM airflow, and 66.5 Pa static pressure.

🔧 Assembly Configuration
The four fans are arranged side by side on a single support structure, forming a complete forced-ventilation module.
Each fan has its own wiring and connector, already installed on the assembly. The structure therefore allows the component to be used as a multiple-fan cooling unit, rather than purchasing and installing the four fans individually.
The photographs also clearly show the rear protective grilles, fan mounting points, and the metal support plate.
⚡ Function in the Cooling System
The assembly is designed to create a high forced-airflow, useful for removing heat generated by electrical and electronic equipment.
With 4 fans providing approximately 46.6 CFM each, the assembly theoretically provides a total airflow capacity of approximately 186.4 CFM, when the fans operate under the same conditions and without considering losses caused by the structure and back pressure.
It is therefore particularly suitable for systems requiring cooling distributed over a large surface area.
🏭 Applications
The assembly can be used for cooling:
- Inverters and converters
- UPS systems and power supplies
- Electrical cabinets
- Electronic enclosures
- Industrial automation systems
- Power electronics
- Telecommunication equipment
- Industrial systems with forced ventilation
- Racks and electronic equipment with high heat dissipation
The characteristics of the AFB0812SH are suitable for applications requiring high airflow, static pressure, and continuous operation.
🏗️ Installation
Each fan features the standard industrial 80 × 80 × 25.4 mm format with mounting holes integrated into the frame.
The assembly must be installed by checking:
- 12 V DC power supply
- Correct connection of the connectors
- Free movement of all four impellers
- Airflow direction
- Available space inside the equipment
- Any rotation-monitoring system
It is important not to confuse the complete assembly with a single fan: the sale concerns 4 Delta AFB0812SH fans mounted on their support structure.
🛡️ Product Condition
The assembly is used and shows dust, signs of use, and normal installation marks on the fans, wiring, and metal structure.
The photographs show all four fans physically intact, with blades and frames without obvious structural breaks.
Electrical operation is not declared tested based on the photographs alone. Before use, it is recommended to individually test all four fans, checking startup at 12 V DC, current consumption, rotation, bearing noise, and correct operation of the signal available on the wiring.
📦 Package Contents
The sale includes:
- 1 complete assembly
- 4 × Delta Electronics AFB0812SH
- 4 brushless DC 12 V fans
- Wiring and connectors shown in the photographs
- Metal support structure
🚀 Final Description
The Delta Electronics AFB0812SH assembly is a professional forced-cooling solution consisting of four 12 V brushless DC axial fans, each with a nameplate current rating of 0.51 A, 80 × 80 × 25.4 mm format, approximately 4,000 rpm, 46.6 CFM airflow, and 66.5 Pa static pressure.
The configuration on a single metal support plate, with four pre-wired fans equipped with connectors, makes the component particularly interesting as a replacement module for industrial systems, inverters, UPS systems, electrical cabinets, and power electronics.
