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.
Description
Ebmpapst D3G146-AH50-16 is a 146 mm forward-curved, dual-intake EC centrifugal fan that combines the M3G074-CF motor, impeller, and flanged housing as one air-moving assembly.

Air enters both sides of D3G146-AH50-16 and leaves through the housing outlet, while the clockwise impeller and horizontal motor shaft define the required mechanical orientation.

The single-phase supply for D3G146-AH50-16 feeds its integrated EC motor electronics; protective earth is connected separately, and the internally connected thermal protector responds to motor overload.

Galvanized sheet steel forms the D3G146-AH50-16 housing and impeller, while a die-cast aluminum electronics enclosure and vibration-damped motor suspension separate the airflow components from the electrical assembly.
