The K3G500-PB24-W5 from EBM-Papst is a powerful EC centrifugal module with backward-curved blades, designed for demanding ventilation and air handling applications in industrial and unit environments. The module delivers an airflow of up to 8685 m³/h and is powered by the M3G150-IF EC motor with a rated voltage of 400 V AC. Thanks to its cube design (FanGrid), multiple units can be easily combined into larger fan arrays.
This product is an excellent fit for air handling units, refrigeration systems, and process ventilation where high efficiency, quiet operation, and smart control are required. The integrated PI controller and MODBUS RTU via RS-485 make the unit easy to integrate into modern control systems.

| Motor frame | The stand consists of a galvanized steel plate base plate and support brackets in black lacquered steel with aluminum spacers. The inlet nozzle is made of galvanized steel plate. The fan module is designed with a cube design (FanGrid) and can be assembled with multiple units using angle, side, and cross connectors (accessories). Assembly is carried out with the shaft horizontally and the support legs vertically according to the product drawing. The unit can be attached to the floor, wall, or ceiling with M8 screws. |
| Casing | cast aluminum, cube design |
| Impeller | The impeller is a backward-curved, single-inlet centrifugal fan impeller with 5 blades made of sheet aluminum. The rotor surface is painted black. The impeller has a size of 500 mm and is designed for high efficiency and low sound pressure. At the optimal efficiency point, the impeller provides an airflow of 8685 m³/h at a static pressure build-up of 1071 Pa. |
