D2E146-CD51-09 ebmpapst 230V 146mm AC Centrifugal Fan

Description

The ebmpapst D2E146-CD51-09 is a robust 230 V single-phase AC dual-inlet centrifugal fan featuring a 146 mm forward-curved galvanized steel impeller integrated into a heavy-duty scroll housing. Driven by the M2E068-DF external rotor motor, this unit is engineered for stable air displacement in industrial environments, delivering a powerful airflow at 1850 RPM with a power consumption of 230 W. The design features a galvanized steel housing and impeller, an unpainted rotor surface, and a PA plastic guard grille for enhanced safety. Optimized for high-resistance systems, it requires a minimum back pressure of 200 Pa to maintain operational stability and prevent motor overload. This compact, all-metal air-moving solution is ideal for air conditioning units, laboratory fume hoods, and electronic cabinet cooling across an ambient temperature range of -25 °C to 30 °C.
