The part number **W2AC-A22A-R2SLASHQ** refers to a high-performance **Industrial AC Cooling Fan**, typically manufactured by brands like **Sanyo Denki** or specialized thermal management providers. This specific model is designed for high-reliability environments such as server racks, control panels, and industrial machinery. --- ### 🛠️ Technical Specifications Below are the primary electronic and mechanical characteristics associated with this series: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Current / Power** | ~0.10A - 0.15A (approx. 18W - 22W) | | **Speed** | 2,700 - 3,100 RPM | | **Airflow** | High Volume (measured in CFM or m³/min) | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Material** | Aluminum Die-cast Frame / Plastic Impeller | | **Termination** | Lead Wires or Terminals | --- ### 🔍 Component Breakdown #### 1. The Motor Structure * **Shaded Pole or Capacitor Run:** These fans generally utilize an AC induction motor. It is brushless, which reduces electronic noise and eliminates wear on brushes, leading to a lifespan often exceeding 50,000 hours. * **Impedance Protection:** The "A22A" segment often signifies internal impedance protection. If the fan blades are blocked, the motor is designed to resist burning out by limiting the current automatically. #### 2. Mechanical Design (The "W2AC" Series) * **Dual Ball Bearings:** Unlike "Sleeve" bearings, ball bearings allow the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting the lifespan. * **Thermal Resistance:** These units are designed to operate in high-temperature environments, typically rated up to **70°C**. #### 3. Suffix Meaning ("R2SLASHQ") * **R2:** Often indicates a specific revision or a version with lead-wire lengths customized for specific industrial enclosures. * **SLASHQ (/Q):** In industrial coding, this usually denotes a "Quiet" version or a "Quick-connect" terminal modification, ensuring the fan meets specific noise decibel standards while maintaining airflow. --- ### ⚠️ Application & Maintenance * **Mounting:** Use standard M4 or M5 screws. Ensure the airflow direction (indicated by an arrow on the frame) matches your thermal exhaust strategy. * **Electrical Safety:** Since this operates at mains voltage (220V+), ensure the frame is grounded if it is installed in a metal chassis. * **Dust Management:** In industrial settings, these fans should be paired with a filter kit to prevent debris from stalling the impeller. ---
