1. Product Overview

• Model: ebmpapst R3G310-AI39-71
• Type: Industrial Compact Anti-Corrosion High-Efficiency Axial Fan
• Core Specs: 310mm epoxy-coated impeller, IP55, IE4 motor (300W), 230V/50-60Hz, 1500r/min, airflow 7,000-10,500 m³/h, 90Pa static pressure, noise ≤70dB(A), -20~70℃ operating temp, wall/horizontal mounting, 500h salt spray resistance.

2. Key Features & Benefits

• Anti-corrosion: Epoxy coating + IP55, 500h salt spray resistance (pH 4-9) for mild-corrosion scenarios.
• High-efficiency: IE4 motor saves ~900kWh/year, 300W low power with 10,500 m³/h high airflow.
• Durable & safe: IP55 protects against sprayed water/dust; dual-sealed bearings last ≥65,000 hours.
• Compact: 7.2kg weight, ≤190mm thickness, easy to install in narrow spaces.

3. Applications

• Coastal small workshops: Medium-area ventilation with sea air corrosion resistance.
• Marine electrical cabinets: Anti-corrosion cooling for onboard electrical equipment.
• Chemical auxiliary areas: Ventilation for mild-corrosion auxiliary production equipment.
• Mild-corrosion production lines: Low-noise auxiliary airflow near workstations.
