The EBM PAPST Impeller (Part Number: R2S133-AE77-27) is a high-performance thermal management component designed for efficient airflow in electronic cooling applications. Manufactured in Germany, this backward-curved, single-intake AC centrifugal fan offers reliable operation with optimized airflow and low noise levels.
Thermal Overload Protection: Internal TOP (Thermal Overload Protector)
Touch Current IEC 60990: < 0.75 mA
Performance Curves
Air performance data measured according to ISO 5801 installation category A, with detailed curves available for 50 Hz and 60 Hz operation. The curves illustrate airflow (CFM and m³/h) versus pressure (Pa and inH2O), along with sound level data.
Additional Details
Connection: Cable with AWG20, 2x crimped splices
Accessory Part (not included): Inlet ring 09566-2-4013
Max. Screw Clearance: 5 mm
Connection Diagram: Includes L (blue), N (brown), and Thermal Overload Protector (TOP)
Disclaimers
All specifications are subject to change. For detailed performance data and installation guidelines, please refer to the datasheet.
