The part number **W2AC-AC3B-R2/Q** refers to a high-performance **Industrial AC Axial Fan**, typically manufactured by brands like **ebm-papst** or equivalent industrial thermal management providers. This specific model is designed for heavy-duty cooling in server racks, power supplies, and control cabinets. --- ### ## Technical Specifications Breakdown The following table outlines the core electronic and mechanical characteristics of the unit: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Standard Single Phase) | | **Frequency** | 50/60 Hz | | **Power Consumption** | Approximately 25W - 30W | | **Bearing Type** | Dual Ball Bearing (Long Life) | | **Airflow Capacity** | ~100 to 115 CFM (Cubic Feet per Minute) | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Reinforced Plastic or Steel | | **Connection Type** | 2-Terminal or Lead Wires | --- ### ### Key Electronic Features 1. **Induction Motor:** The fan utilizes a shaded-pole or capacitor-run AC induction motor. These are favored in industrial settings for their reliability and lack of brushes, which minimizes electrical noise (EMI). 2. **Thermal Protection:** Most versions of the R2/Q series include internal impedance protection or a thermal cutoff. This prevents the motor from burning out if the blades are obstructed (locked rotor condition). 3. **Dielectric Strength:** Designed to withstand high voltage spikes common in industrial power grids, ensuring the insulation does not break down at 230V operation. 4. **Ball Bearing System:** Unlike cheaper "sleeve" bearings, the dual ball bearing system allows for mounting in any orientation (horizontal or vertical) and provides an MTBF (Mean Time Between Failures) of over 50,000 hours. --- ### ### Part Number Suffix Meanings (`/Q`) * **R2:** Usually denotes a specific revision level or a specific wiring configuration (e.g., specific lead length or connector type). * **SLASH Q (/Q):** This often indicates a **Quality/Quiet** certification or a specific "Quick-connect" terminal layout depending on the exact manufacturer's internal coding. In many industrial contexts, it implies the unit has undergone enhanced vibration testing. --- ### ### Common Applications * **Enclosure Cooling:** Maintaining ambient temperatures in electrical panels. * **Networking Gear:** Cooling high-density server racks. * **Industrial Machinery:** Dissipating heat from motor drives and CNC controllers.
