R2E220-AA40-B8
Application: Inverter cabinet Cabinet door, wind power, cabinet
Nominal data
Description
R2E220-AA40-B8 ebmpapst Specification drawing：
Fan Design
The centrifugal impeller directs air radially from the inlet toward the outlet. For equipment replacement, the fan should be evaluated by its complete performance curve and installation geometry rather than airflow alone.
Electrical and Mechanical Checks
Confirm 230 V supply compatibility, frequency, motor connection, mounting dimensions, inlet geometry and available space. Technical references for this model also identify IP44 protection and ball-bearing construction; protection performance remains dependent on correct installation.
Typical Equipment Applications
R2E220 centrifugal fans can be considered for compatible industrial equipment where compact centrifugal airflow is required, such as electrical cabinets, power electronics, inverter cooling and other ventilation assemblies. Final suitability must be checked against the required operating point and environment.
Replacement Selection
When replacing an existing R2E220-AA40-B8, compare the exact suffix and motor data. Other R2E220-AA40 versions may look similar while differing in electrical or mechanical details.
FAQ
Q1. What type of fan is R2E220-AA40-B8?
A1. It is an ebm-papst AC centrifugal/radial fan in the R2E220 family.
Q2. What is the nominal speed?
A2. Common technical references list 2,600 rpm. Confirm the value on the exact manufacturer documentation for your unit.
Q3. What airflow is listed for this model?
A3. Technical references list approximately 865 m³/h. System airflow will depend on the operating point and installation resistance.
Q4. Can R2E220-AA40-05 replace R2E220-AA40-B8?
A4. Do not assume interchangeability from the family name. Compare the exact electrical, mechanical and performance data for both suffixes.
Q5. What should I provide for a replacement check?
A5. Send the complete model number, fan label photo, voltage, equipment type, mounting dimensions and required airflow/static pressure.
Need help confirming the correct fan for a replacement or new project? Send APAC FAN the existing model number, required airflow, static pressure, voltage, installation dimensions and control requirements. Our team can help you identify a suitable product and check availability.
