- IP44 protection rating resists dust and splashing water ingress
- Thermal overload protector wired internally safeguards motor from overheating
Target Application
This Ebm-Papst centrifugal fan operates on 230 VAC mains power at 50 or 60 Hz. It delivers up to 414.94 CFM airflow at 2560 RPM using a 225 mm fibreglass-reinforced plastic impeller. The IP44 rating and integrated thermal overload protector suit industrial enclosures or server racks that require direct AC-powered spot cooling.
Upgrade Path
The unit replaces older shaded-pole or sleeve-bearing blowers that lack the ball-bearing motor and higher 210 W peak input at 60 Hz. The jump is worth it when the installation demands continuous S1 operation between -25 °C and 70 °C ambient, or when the 3.5 µF run capacitor and sub-0.75 mA touch current simplify compliance with EN 60034-5 and IEC 60990.
Build Integration
Flange mounting with horizontal shaft or rotor-on-bottom orientation fits standard cut-outs without additional brackets. The variable cable exit and condensate discharge holes on the rotor side ease routing in tight cabinets. Ball bearings and insulation class F free the designer from frequent bearing swaps and allow storage extremes down to -40 °C.

คำถามเกี่ยวกับสินค้านี้
What flange dimensions and mounting position does the 225 mm R2E225-RA92-09 require?
The fan uses a 225 mm flange mount and must be installed with the shaft horizontal or the rotor on the bottom; rotor-on-top orientation is only available on request.
How is the 230 V AC motor wired and what capacitor value is needed?
Connect the single-phase motor to 230 V AC at 50 or 60 Hz and fit the supplied 3.5 µF, 450 VDB capacitor; the thermal overload protector is already wired internally.
When should the ball bearing or impeller be checked on the R2E225-RA92-09?
Inspect the ball bearing for noise or play and verify the PA6 fibreglass-reinforced impeller for cracks during scheduled maintenance; the motor is rated for continuous S1 operation up to 70 °C ambient at 50 Hz.
