The **OA2A8020-R01** is a high-performance, industrial-grade **AC Axial Fan** manufactured by Orion Fans. This specific part is designed for thermal management in environments where high airflow and durability are required. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for the OA2A8020-R01: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230 VAC (50/60 Hz) | | **Frame Size** | 80mm x 80mm x 25mm | | **Airflow** | ~18 to 22 CFM (Cubic Feet per Minute) | | **Rated Power** | 11 Watts | | **Rated Current** | 0.07 Amps | | **Noise Level** | ~30 dB | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Wire Leads | --- ### 2. Key Electronic Components & Design #### Motor Construction The unit utilizes a **Shaded Pole Induction Motor**. This design is common for AC fans because it is brushless, highly reliable, and lacks sensitive electronic controllers that might fail under high heat. It is impedance protected, meaning the motor can withstand a locked rotor condition without catching fire. #### The Bearing System The "R" in the suffix often denotes a **Ball Bearing** system. Dual ball bearings provide several electronic and mechanical advantages: * **Orientation Agnostic:** Can be mounted vertically or horizontally without affecting lifespan. * **Longevity:** Rated for approximately 60,000 hours of continuous use. #### Housing and Impeller * **Frame:** Die-cast aluminum (provides EMI shielding and heat dissipation). * **Impeller:** PBT, UL94V-0 Thermoplastic (Flame retardant). --- ### 3. Application Use Cases Due to its 230V rating and compact 80mm size, it is typically found in: * **Server Racks:** Cooling power supplies and network switches. * **Industrial Control Panels:** Preventing heat buildup in PLC enclosures. * **Medical Equipment:** Reliable cooling for diagnostic machines. ---
