Fans R2E133-BH66-05 Centrifugal Fan 133mm 203CFM 230V 24W

SKU CH-ZARA-HW05K

133 mm centrifugal fan moves 203 CFM at 230 V and 24 W with backward-curved blades and an attached capacitor

  • 133 mm centrifugal fan delivers 203 CFM airflow
  • 24 W motor runs on standard 230 V 50/60 Hz supply
  • Backward-curved blades need no scroll housing for versatile mounting
  • Integrated 11 µF 400 V capacitor simplifies installation
  • CE-approved design operates from -25 °C to 60 °C ambient

Ebmpapst R2E133-BH66-05 Centrifugal Fan

The Ebmpapst R2E133-BH66-05 is a 133mm centrifugal fan built for equipment cooling where backward-curved blades and a compact external-rotor motor are required. It suits integrators and maintenance teams fitting replacement units into industrial enclosures, HVAC modules or custom chassis that demand 230 V AC operation.

230 V AC single-phase motor

The fan runs on 230 V AC at 50 or 60 Hz, drawing 0.11 A at 50 Hz and 0.13 A at 60 Hz with a 11 µF, 400 V DB capacitor included. Speed is rated at 2800 min⁻¹ on 50 Hz and 3300 min⁻¹ on 60 Hz, while power consumption stays at 24 W and 27 W respectively, so the electrical supply must match these exact voltage, frequency and current figures.

Continuous airflow up to 203 CFM across a wide

At zero back pressure the fan delivers 203 CFM and is rated for ambient temperatures from -25 °C to 45 °C at 50 Hz, extending to 60 °C at 60 Hz. The motor maintains 100 % speed control via analog or serial interface without a scroll housing, allowing sustained forced-air cooling in space-constrained installations.

Questions about this item

How does the 203 CFM airflow perform inside a typical enclosure?

The fan delivers 203 CFM at zero static pressure; actual flow drops as resistance from filters, grilles or ducting increases.

What does the 230 VAC rating mean for mains connection and speed control?

It runs directly on 230 VAC at 50 or 60 Hz, drawing 0.11–0.13 A, and supports 100 % speed control via analog or serial interface.

What mounting provisions does the 133 mm diameter housing require?

The unit includes an inlet ring and capacitor; the backward-curved impeller operates without a scroll housing, so it mounts on a flat panel with the supplied ring.
