Description
The ebmpapst K3G450-PA31-03/F01 is an ultra-high-performance 3-phase EC Centrifugal Fan module from the RadiPac series, featuring a 450 mm backward-curved aluminum impeller. Driven by the heavy-duty M3G150-FF (Size 150) GreenTech EC motor, this 33.2 kg industrial unit operates on a 380-480 VAC supply and is designed for high-static pressure applications such as AHUs and industrial cooling grids. At its optimum efficiency point, it delivers 8710 m³/h with a static pressure increase of 1212 Pa, reaching a peak speed of 2490 RPM with a power consumption of 4.5 kW. The unit is constructed with a 5-blade aluminum impeller, a galvanized steel inlet nozzle, and a black-painted steel support bracket. Equipped with advanced MODBUS V6.0, an integrated PI controller, and RFID (ISO 15693) compatibility, the K3G450-PA31-03/F01 offers a mission-critical, IE5-level cooling solution with IP55 protection, capable of operating in extreme temperatures down to -40 °C.

Application
The ebmpapst K3G450-PA31-03/F01 is a mission-critical, ultra-high-power RadiPac module engineered for the most demanding industrial air-moving environments, such as large-scale Air Handling Units (AHU), Clean Room recirculation systems, and high-density Data Center FanGrids. Featuring a heavy-duty 4500 W M3G150-FF motor and a 5-blade backward-curved aluminum impeller, this unit is specifically optimized to deliver a massive static pressure increase of 1212 Pa, ensuring consistent air volumes (8710 m³/h) even through high-efficiency HEPA filters or dense cooling coils.
The integration of MODBUS V6.0 and RFID (ISO 15693) compatibility allows for advanced predictive maintenance and effortless asset management, enabling technicians to read operational data wirelessly via mobile devices. With its specialized support bracket and black-painted steel structure, the 33.2 kg unit is built for extreme mechanical stability under S1 continuous-duty cycles. Furthermore, its ability to perform occasional start-ups at -40°C and its robust IP55/H1 protection make it an ideal choice for outdoor HVAC infrastructure, industrial process cooling, and commercial refrigeration plants operating in harsh global climates.
