The ZIEHL-ABEGG GR40I-ZID.DG.CR is an EC centrifugal blower for hvac systems, supporting equipment thermal management and integration.
Data includes 3~380-480 V operation, airflow up to 9400 m³/h and pressure up to 1400 Pa so designers can evaluate the required duty point against installation losses. The datasheet lists bionic blade geometry for durable motor support. Listed noise is 55 dB at the stated test point. Careful attention to wiring and inlet geometry supports efficient heat removal without unnecessary aerodynamic loss.
Technical buyers can evaluate GR40I-ZID.DG.CR by confirming the intended duty point, mounting, electrical connection and installation limits. Its engineering data set supports model verification during OEM development while keeping the duty point central.
Check for blocked airflow paths, incorrect supply, loose wiring, abnormal rotation or system resistance before consulting the exact service documentation.
It is listed for AHU. Confirm voltage, duty point, dimensions and mounting against the equipment requirements before selection.
Match required airflow and pressure on the exact performance curve, then verify voltage, power, dimensions and environmental limits.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
