Industrial Backward Centrifugal Fan
The Ebm-Papst R2D225-AV02-15 is a 400-415 V AC three-phase backward centrifugal fan built for industrial cabinet and HVAC cooling. Its 225 mm PA6 impeller with seven blades runs on ball bearings and delivers IP44 protection for dusty or damp environments. Maintenance teams and OEM integrators specify it for Rittal enclosures and similar forced-air systems.
Replaces Worn Three-Phase Cabinet Fans
This unit serves as a direct swap for failed or ageing 400-415 V AC centrifugal blowers in the same 225 mm frame. The jump is worth it when the existing motor draws near 0.26 A at 50 Hz or 0.27 A at 60 Hz and the insulation class B rating matches the original spec. It restores rated airflow without redesigning ductwork or mounting points.
Verify Voltage Phase And Clearance Before Ordering
Confirm the supply is three-phase 400-415 V AC at 50 or 60 Hz and that the 225 mm diameter plus motor depth fits the cabinet cutout. Check that the 120 W at 50 Hz or 165 W at 60 Hz power draw suits the circuit protection. Ensure ambient temperatures stay within the -25 °C to 60 °C range and that IP44 meets the enclosure rating.

Questions about this item
What mounting clearance does the 225 mm backward-curved impeller need inside a Rittal cabinet?
The fan housing is 225 mm in diameter; allow at least that much clear width and depth plus space for the 68 mm motor body and wiring entry.
How do I wire the three-phase 400–415 VAC supply to the M2D068-DF motor, and what mistake trips the overload?
Connect L1, L2, L3 to the terminal block matching the 0.26/0.27 A rating; the common error is swapping two phases, which reverses rotation and reduces airflow.
When should I replace the ball bearings in the M2D068-DF motor?
Inspect bearings at each scheduled shutdown; replace if audible rumble or vibration appears, typically after several years at the rated -25 to 60 °C ambient range.
