R3G310-AZ88-01 ebmpapst 400V EC Centrifugal Fan 310mm

Description

The ebmpapst R3G310-AZ88-01 is an EC Centrifugal Fan with measuring 310 mm in diameter, powered by the M3G112-IA motor. This three-phase fan operates on a nominal voltage of 400 VAC (range 380..480 VAC) at 50 Hz/60 Hz frequencies. It delivers a maximum air performance of 4085 m3/h and a static pressure increase of 1567 Pa at a high speed of 4100 RPM. With a power consumption of 3240 W and a current draw of 4.9 A, the R3G310-AZ88-01 is built for continuous operation (S1) and features IP54 protection, making it suitable for applications requiring high pressure, compact design, and variable speed control in industrial HVAC and air handling systems.

Application
The R3G310-AZ88-01 EC Centrifugal Fan is an ideal solution for applications requiring high-pressure airflow in a relatively compact size. It is typically used in small-to-medium Air Handling Units (AHU), heat exchangers, clean rooms, control panel cooling, and industrial ventilation systems where the high static pressure capability of a backward-curved impeller is essential to overcome system resistance.
