The **W2AC-AB1A-R** is a specific model within a series of industrial-grade **AC Axial Fans**, typically manufactured by brands like **Fulltech** or similar industrial cooling solution providers. These fans are designed for high-performance thermal management in server racks, control cabinets, and power supplies. --- ### 1. Key Technical Specifications The part number "W2AC-AB1A-R" breaks down into specific electrical and mechanical characteristics: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Standard Range: 100V - 120V) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | Approx. 0.20A - 0.25A (Model dependent) | | **Bearing Type** | Dual Ball Bearing (Indicated by 'B' or 'R' suffixes) | | **Frame Material** | Die-cast Aluminum (Ruggedized) | | **Impeller Material** | Thermoplastic (UL 94V-0 Rated) | | **Termination** | Lead Wires or Terminals | --- ### 2. Internal Electronic Components Unlike DC fans that use a PCB with a hall-effect sensor and driver IC, this AC fan relies on a **Shaded Pole Motor** or a **Permanent Split Capacitor (PSC)** design: * **Motor Windings:** Copper windings with high-temperature insulation (Class B or F). * **Impedance Protection:** The "AB1A" variant usually features internal impedance protection. This means if the fan blades are locked (stall condition), the resistance of the windings prevents the motor from overheating and catching fire. * **Ball Bearing System:** The "R" often denotes a "Reverse" airflow or a specific "RoHS" compliance and bearing refinement. Dual ball bearings allow for operation in any orientation and provide a longer MTBF (Mean Time Between Failure), typically >50,000 hours. --- ### 3. Performance Data | Feature | Measurement | | :--- | :--- | | **Airflow** | ~90 to 110 CFM (Cubic Feet per Minute) | | **Static Pressure** | ~0.30 - 0.40 in-H2O | | **Noise Level** | 45 - 50 dB(A) | | **Operating Temp** | -10°C to +70°C | --- ### 4. Typical Applications * **Enclosure Cooling:** Dissipating heat from industrial electrical panels. * **Ventilation:** Used in commercial food equipment and drying systems. * **IT Infrastructure:** Heavy-duty cooling for legacy server chassis. ---
