D2E146-AP47-C3 ebmpapst Centrifugal Fan With Capacitor M2E068-EC 230V 50/60Hz

1.Overview of the D2E146-AP47-C3 ebmpapst

The D2E146-AP47-C3 is a high-quality centrifugal fan from ebmpapst, designed for demanding industrial cooling applications. Utilizing backward centrifugal technology and incorporating AC technology, it delivers high airflow and high static pressure within confined spaces, making it ideal for cooling the needs of inverters, rectifier units, and other similar equipment.

The fan features an integrated external rotor motor. This innovative design cleverly places the motor within the impeller, achieving effective motor cooling and resulting in a remarkably compact overall structure. Its metal construction ensures long-term stable operation in harsh industrial environments.

Product Highlights

High Airflow and High Air Pressure

• Forward-curved impeller + optimized volute, rated airflow 970 m³/h, maximum static pressure over 200 Pa, easily penetrating high-density heat sinks.

Low Noise and Energy Saving

• Utilizes a GreenTech EC adjustable speed motor, with efficiency ≥30% higher than traditional asynchronous motors; noise level at 2050 rpm is only about 65 dB(A), significantly improving the overall sound quality of the equipment.

Wide Voltage and Wide Temperature Operation

• 230 V AC ±10%, universal for 50/60 Hz; continuous and reliable operation in ambient temperatures –25 °C … +50 °C, suitable for high altitudes and outdoor cabinets.

Long Life and Maintenance-Free

• Oil-free ball bearings, L10 life ≥ 40,000 h (at 40 °C), IP44 protection rating for dust and moisture protection, galvanized steel shell for corrosion resistance.

Flexible installation

• Single air inlet structure, 146 mm standard flange, three-hole 120° installation; optional air guide ring, protective net and PWM/0-10 V speed control module to quickly match your air duct.
