Features:
- Forward-curved, dual-intake EC fan with a flanged housing
- 146 mm impeller driven by the M3G074-CF motor
- Single-phase 230 VAC supply with a 200 to 277 VAC range
The D3G146-AH50-16 combines a galvanized sheet-steel housing and impeller with a die-cast aluminum electronics enclosure.
Vibration-damped motor suspension and ball bearings support continuous S1 operation of D3G146-AH50-16.
Its internally connected thermal overload protector works with IP44 construction and customer-connected protective earth on D3G146-AH50-16.
The Ebmpapst D3G146-AH50-16 EC Centrifugal Fan may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Power and Connection Path
- Line conductor: The black L lead carries the single-phase supply into D3G146-AH50-16.
- Neutral conductor: The blue N lead completes the AC supply path to the fan electronics.
- Protective earth: The green/yellow PE lead must be connected for Protection Class I operation.
- Internal bridge: Connection 13 is shown as a fixed internal bridge for full-speed operation in the retrofitted connection.
Fan and Motor Assembly
- Impeller: A 146 mm forward-curved, dual-intake wheel is formed from Sendzimir-galvanized sheet steel.
- Housing: The galvanized sheet-steel scroll terminates in an integral rectangular mounting flange.
- Electronics enclosure: Die-cast aluminum protects the electronic section of D3G146-AH50-16.
- Motor support: The M3G074-CF motor is vibration-damped on both sides and runs on ball bearings.
Mounting Boundaries
- Shaft position: Install D3G146-AH50-16 with the motor shaft horizontal.
- Rotation: The impeller turns clockwise when viewed toward the rotor.
- Drainage: No condensation drainage holes are provided in the assembly.
- Envelope: The product drawing shows a 270 mm width, 219 mm height, and 205 mm depth for layout planning.
Measured 50 Hz Airflow
- Free-air point: D3G146-AH50-16 delivers 1125 m³/h at 0 Pa while running at 1700 rpm.
- Mid-pressure point: At 150 Pa, the measured airflow is 935 m³/h at 1935 rpm.
- Higher-pressure point: At 350 Pa, the measured airflow is 660 m³/h at 2370 rpm.
- Electrical input: These three measured points use 230 V, 50 Hz, 165 W, and 1.2 A.
