The ZIEHL-ABEGG GR45I-ZID.GG.CR is an EC centrifugal blower for hvac systems, supporting equipment thermal management and integration.
Data includes 400 V operation, airflow up to 6929 m³/h and pressure up to 2864 Pa so designers can evaluate the required duty point against installation losses. The datasheet lists bionic blade geometry, PWM/0-10 V speed control for durable motor support. Listed noise is 90 dB at the stated test point. Duty-point verification and a low-obstruction inlet help maintain predictable airflow and dependable fan operation.
The documented profile helps structure design reviews for installed equipment before release to production. The resulting specification is easier to review across prototype, production and maintenance stages.
Its EC centrifugal fan configuration and a listed pressure capability of 2,864 Pa provide model-specific criteria for matching Air Handling Units systems.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
It is listed for Air Handling Units. Confirm voltage, duty point, dimensions and mounting against the equipment requirements before selection.
