R2E120-BB76-11/A01 ebm-papst

Q1: What are the key technical specifications of the ebm-papst R2E120-BB76-11/A01 centrifugal fan?
A1: The ebm-papst R2E120-BB76-11/A01 is a 120 mm centrifugal fan with a rated voltage of 230 V and input power of 55 W. It operates at 2350 RPM with a rated current of 0.24 A, compatible with 50/60 Hz frequency. Adopting a compact design typical of ebm-papst’s industrial fans, it balances efficient airflow output with low power consumption, suitable for targeted ventilation and cooling tasks.

Q2: What structural design features make this centrifugal fan stand out?
A2: This fan features a robust structural design with ball bearings for stable and long-lasting operation. It adopts a compact layout that integrates the motor with the impeller, optimizing space utilization while ensuring effective self-cooling of the motor. The impeller and housing are engineered to minimize airflow resistance, and the overall construction adheres to ebm-papst’s strict quality standards for industrial-grade reliability.

Q3: What application scenarios is the R2E120-BB76-11/A01 centrifugal fan best suited for?
A3: The fan is ideal for equipment cooling and ventilation in industrial and commercial settings, particularly for machine tool heat dissipation. It also fits well in small HVAC terminal units, industrial control cabinets, and precision equipment enclosures that require 230 V power supply and compact 120 mm size. Its low-noise and efficient performance make it suitable for scenarios where stable airflow and quiet operation are required.

Q4: What critical points should be noted during installation to ensure optimal performance?
A4: Ensure the installation base is flat and sturdy, with horizontal error controlled within 0.1mm/m to reduce vibration. Keep the air inlet unobstructed, leaving at least 1.5 times the fan diameter of space in front of it. Connect air ducts smoothly to minimize bends and avoid forcing connections that add weight to the fan. Confirm the power supply matches 230 V and 50/60 Hz requirements before wiring to prevent motor damage.

Q5: How to maintain the ebm-papst R2E120-BB76-11/A01 centrifugal fan for extended service life?
A5: Regularly clean the impeller and housing to remove dust buildup that affects airflow and increases wear. Periodically check the tightness of mounting bolts and connections to prevent loosening from vibration. Avoid operating the fan in high-temperature, high-humidity, or dusty environments without proper protection; use filters if dust is excessive. If abnormal noise or vibration occurs, stop operation immediately to inspect for bearing wear or impeller obstruction.
