What this centrifugal fan delivers

The Fans R2E250-AC09-05Motor is a 250 mm centrifugal fan built by ebm-papst for 230 V AC mains supply. It draws 1.16 A and produces 265 W of mechanical power at 2650 rpm. The external-rotor motor sits inside the impeller, giving a compact design with direct motor cooling. Airflow can reach up to 35000 m³/h in the product line.

Who this suits and who should look elsewhere

Engineers specifying industrial ventilation, HVAC modules or rack-mounted equipment that can accommodate a 250 mm centrifugal impeller will match the 230 V AC input and 2650 rpm operating point. Buyers who need a low-voltage DC fan, a PWM speed signal or an axial form factor will not find those attributes in this unit.

The specification that decides fit

The 230 V AC voltage rating is the single parameter that determines whether this fan can be installed; the system must provide mains-level AC power at that exact voltage.

Questions about this item

How do I mount the 250 mm centrifugal fan and what wiring step is often missed?

Secure the fan with four bolts through the steel housing flanges, then connect the 230 V supply to the terminal block — the step most installers forget is tightening the earth lug to the chassis.

Which part of this 265 W unit will need replacement first and when?

The sealed ball bearings inside the external rotor motor are the only wear item; expect them to last several years of continuous 2650 rpm operation before requiring a full fan swap.

What thermal limit appears first when the fan runs at 2650 rpm continuously?

The motor winding temperature reaches its design ceiling before airflow drops, so sustained 265 W draw at 230 V will trigger thermal protection if inlet air exceeds the rated ambient.
