1. Product Overview

• Model: ebmpapst R3G310-AI39-74
• Type: Industrial Compact High-Efficiency Wide-Temperature External Rotor Axial Fan
• Core Specs: 310mm impeller, IP54 protection, IE4 motor (390W), 380V/50-60Hz, 1900r/min, airflow 1600-2300m³/h, static pressure 145Pa, noise ≤71dB(A), operating temp -20~65℃, dual mounting (side/top).

2. Features & Benefits

• Wide-temperature operation: -20~65℃ adaptive, fits high/low temp workshops and high-altitude environments;
• Universal mounting: Supports side/top installation, compatible with most medium industrial cabinets;
• Efficient & durable: IE4 motor saves ~620kWh/year, high-temp bearings + IP54 protection for long service life.

3. Applications

• High-temperature industrial cabinets: Cooling for electrical control systems in 40-65℃ workshops;
• 60-120kW inverters: Stable heat dissipation in variable-temperature production lines;
• High-altitude workshops: Adaptation to large day-night temperature differences (e.g., plateau factories);
• Variable-temperature equipment: Cooling for machinery with alternating cold/hot operating conditions.
