## Technical Overview: W2CE-111-R/UL The **W2CE-111-R/UL** is a high-performance, AC axial fan manufactured by **Orion Fans**. This specific model belongs to the "Dual Voltage" or "High Performance" series, designed for industrial-grade thermal management. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Frame Material** | Die-cast Aluminum (Rugged construction) | | **Impeller Material** | PBT, UL94V-0 Plastic (Flame retardant) | | **Bearing System** | Dual Ball Bearing (Long life, multi-orientation) | | **Voltage Range** | 115 VAC (Rated) | | **Frequency** | 50/60 Hz | | **Airflow** | ~110 - 130 CFM (Cubic Feet per Minute) | | **Connection Type** | Terminals (T) or Lead Wires (W) | | **Certifications** | UL recognized, RoHS compliant | --- ### 2. Functional Components * **Motor Design:** Shaded pole induction motor. It is impedance protected, meaning the motor can withstand a locked-rotor condition for a period without catching fire or sustaining immediate damage. * **Dual Ball Bearings:** Unlike cheaper sleeve bearings, the ball bearing system allows the fan to be mounted in any position (horizontal, vertical, or angled) and offers a significantly higher MTBF (Mean Time Between Failures), typically exceeding 60,000 hours. * **Safety Features:** The "UL" suffix indicates it meets rigorous Underwriters Laboratories safety standards for electrical insulation and fire resistance. --- ### 3. Part Number Breakdown Understanding the nomenclature helps identify the exact electronic features: | Code | Meaning | | :--- | :--- | | **W2** | Series designation (often refers to specific frame size, usually 120mm x 38mm) | | **C** | High-performance airflow characteristic | | **E** | Voltage indicator (E usually signifies 115V AC class) | | **111** | Internal design/speed code | | **R** | Terminal type (often indicates standard terminal pins) | | **UL** | Safety certification mark | --- ### 4. Applications The W2CE-111-R/UL is typically found in: * **Server Racks:** To exhaust heat from high-density computing. * **Industrial Control Panels:** Protecting PLCs and power supplies from overheating. * **Medical Equipment:** Reliable cooling for sensitive diagnostic machinery. * **Power Supplies:** Large-scale AC-DC converters. ---
