The ZIEHL-ABEGG RH28C-2DD.3I.CR is an AC centrifugal blower for hvac systems, supporting equipment thermal management and integration.
Data includes 400 V operation and airflow up to 2950 m³/h to assist system engineers in validating the planned ventilation circuit. The datasheet lists ball-bearing support for durable motor support. Installed noise depends on the duty point and airflow path. Correct wiring and unobstructed inlet clearance help preserve cooling efficiency, operating stability and service life.
Procurement teams should validate RH28C-2DD.3I.CR against the actual system resistance, electrical connection, fit and environmental limits. Its engineering data set helps manage selection risk in compact cooling projects before the final design-in decision.
Control capability and input method must be confirmed in the exact-model datasheet and wiring diagram; do not infer them from the fan family alone.
The supplied table lists 2,950 m³/h, 3,170 rpm; use the exact datasheet for the complete operating curve.
Compare 280 mm, 400 V, 1,000 W plus mounting, connector and duty-point requirements.
Check for blocked airflow paths, incorrect supply, loose wiring, abnormal rotation or system resistance before consulting the exact service documentation.
