Technical Performance of A4D400-AN04-01 ebm-papst
The A4D400-AN04-01 is a robust 400mm axial fan designed for high-capacity air movement in industrial environments. This model utilizes a 3-phase external rotor motor, which is synonymous with durability and efficiency. Its primary application lies in large-scale ventilation systems, dry coolers, and industrial condensers where a consistent airflow is critical to prevent system overheating. The sickle-shaped blades are manufactured from sheet steel and are aerodynamically optimized to provide a high volume of air at low noise levels, making it ideal for facilities with strict acoustic regulations.
Core Technical Specifications
- Impeller Diameter: 400 mm.
- Electrical Supply: 400 VAC, 3-phase (50/60 Hz).
- Input Power: 135W – 200W depending on static pressure.
- Protection: IP44 (Internal thermal overload protector).
- Airflow Direction: Exhaust over struts (Type V).
Lifecycle & Engineer Support
Lifecycle State: This part number is Active and serves as a reliable replacement for older 400mm AC fans in industrial HVAC units. Diagnosis & Troubleshooting: Maintenance technicians should check the capacitor (if used in similar 1-phase configurations) or the phase balance in this 3-phase model. If the fan exhibits unusual humming, verify the integrity of the motor windings. Installation Tips: Due to its weight and torque, ensure the mounting bracket is vibration-dampened. Always check that the air intake is free of obstructions to prevent motor stall. Compatibility: Perfectly suited for integration with Siemens SIMATIC controllers and can be speed-managed via standard frequency inverters for energy-saving operations.
