180 mm AC turbo fan for industrial enclosures

The SunnyStar R2E280-AE52-05 is an original EBM-PAPST AC centrifugal blower built for 230 V 50 Hz mains supply. It draws 1.0 A at 225 W and uses a 7 µF 400 VDB capacitor for starting torque. The 180 mm impeller sits in a 280 mm by 125 mm housing with a four-wire power connector.

Replaces legacy R2E280-AE52-17 units in rack

This model directly substitutes the earlier R2E280-AE52-17 variant while keeping the same voltage, frequency and mounting footprint. The swap is worthwhile when the original blower has reached end of life or when a verified OEM replacement is required for compliance paperwork.

Delivers high static pressure for dense airflow

The turbo centrifugal design pushes air through restrictive filter banks, heat-exchanger fins or long duct runs where axial fans stall. Headroom exists for continuous 50 Hz operation at rated current; the unit is not suited for variable-speed control, PWM signalling or low-voltage DC chassis.

Questions about this item

What clearance does the 280 by 125 mm housing need to fit inside a case?

The fan measures 280 mm in diameter and 125 mm deep, so allow at least that much unobstructed space plus room for the four-wire lead.

How do I wire the four-wire AC lead to 230 V 50 Hz mains and where does the 7 µF 400 VDB capacitor go?

Connect the supply wires to 230 V 50 Hz, then fit the 7 µF 400 VDB capacitor across the designated terminals before powering on.

When should the 7 µF 400 VDB run capacitor be replaced to keep the motor running reliably?

Replace the capacitor if the fan fails to start, runs slowly, or shows bulging or leakage, typically after several years of continuous operation.
