R2E280-AE52-05 ebmpapst

Description

R2E280-AE52-05 ebmpapst 230VAC 280mm Ball 225W 2700RPM 4 Wire Leads IP44 Axial Fan

Equipped with the M2E068-EC single-phase motor, the R2E280-AE52-05 operates on a 230VAC/50Hz power supply, delivering a rated speed of 2700 min⁻¹ and an input power of 225W. Under free-air operation (0Pa backpressure), it achieves a robust air flow of 2110 m³/h, efficiently catering to ductless exhaust or light-load air delivery scenarios where unobstructed airflow is critical. Its 11 backward-curved blades are engineered to optimize aerodynamic performance: by minimizing eddy current losses through a precision-contoured design, this configuration enhances energy efficiency by 10–15% compared to traditional forward-curved blade setups, while also reducing noise generation for quieter operation.

As system backpressure increases to 200Pa, the fan maintains stable performance with a consistent airflow of 1655 m³/h and a marginal power increase to 230W, showcasing exceptional adaptability to varying load conditions. Even at the maximum measurable backpressure of 400Pa, it continues to operate reliably, sustaining a flow rate of 1070 m³/h with a power input of 324W—making it well-suited for medium-low pressure applications such as air handling units, industrial control cabinet cooling, and machinery ventilation systems. The backward-curved blade technology not only balances airflow, energy efficiency, and noise control but also ensures stable performance across a wide operational range, positioning the R2E280-AE52-05 as a dependable choice for applications requiring consistent, efficient air movement under moderate dynamic loads.
