GR31I-ZID.DC.CR 116889/A01 is a 3~380-480 VAC centrifugal fan for data centers. Its main supplied feature is 2400 W input power for the listed electrical version. It also lists a 310 mm size specified in the upload data. Review performance curve for spares planning. Check the exact variant before ordering.
Designed for data-center cooling systems, GR31I-ZID.DC.CR 116889/A01 combines ZIEHL-ABEGG engineering with an EC centrifugal fan format suited to OEM integration. The design supports stable thermal management in compact equipment layouts.
The backward-curved centrifugal design follows the ZAbluefin aerodynamic concept, using coordinated wheel and air-path geometry to support efficient pressure development and favorable sound behavior. The arrangement is intended for compact air-handling and cooling equipment.
System qualification for GR31I-ZID.DC.CR 116889/A01 should use the final grille, nozzle and surrounding equipment structure. This helps manufacturers preserve useful airflow, manage sound and define compatible replacements.
For data-center cooling and dry-cooler systems, the GR31I-ZID.DC.CR 116889/A01 EC centrifugal fan moves thermal load away from continuously operating digital infrastructure. Keeping the full suffix in technical records helps avoid mismatched replacements during maintenance.
In HVAC, outdoor air-conditioning and ventilation equipment, ZIEHL-ABEGG GR31I-ZID.DC.CR 116889/A01 supports ventilation duty where filters, coils and duct resistance affect airflow. For purchasing teams, the exact model reference supports controlled sourcing and service identification.
Match the complete model code, voltage, dimensions, mounting arrangement, airflow direction, performance point, and control interface to the equipment.
The upload sheet marks the item as In Stock, but available quantity should be confirmed when the order is placed.
Verify the listed size, mounting pattern, fan housing or nozzle arrangement, airflow direction, and service clearance against the equipment drawing.
Speed-control support is not stated for this exact item in the supplied sources. Confirm the motor and controller version before specifying control hardware.
No model-specific maintenance interval is supplied. Keep the airflow path clean, inspect mounting and electrical connections, and follow the exact product instructions.
The supplied row lists 6800 m³/h airflow, 1860 Pa pressure, 2400 W input, 3700 rpm. Compare these values with the real system operating point, not only the free-air rating.
