R2D225-RA26-15 ebmpapst 400/460V 225mm AC Centrifugal Fan

Description

The ebmpapst R2D225-RA26-15 is a high-duty 400-460 V three-phase AC centrifugal fan featuring a 225 mm backward-curved impeller precision-fabricated from galvanized sheet steel. Driven by the high-torque M2D068-DF external rotor motor, this unit is engineered for powerful air displacement in industrial cooling systems, achieving speeds up to 2850 RPM. Designed for continuous S1 operation, it provides exceptional pressure stability and thermal durability with a high-performance Class F insulation system. This robust 3-phase solution is optimized for heavy-duty applications such as large-scale electronics cooling, industrial heat exchangers, and HVAC ventilation, ensuring reliable operation across demanding ambient conditions.
