The ZIEHL-ABEGG RE28P-4EK.4I.1R is an AC centrifugal blower for hvac systems, equipment cooling, supporting equipment thermal management and integration.
Data includes 230 V operation and pressure up to 450 Pa for comparing the documented operating point with the intended air channel. Its integrated motor and impeller support stable ventilation. Installed noise depends on the duty point and airflow path. An appropriate supply interface and well-planned air path support efficient cooling and reduce thermal stress.
Procurement teams should validate RE28P-4EK.4I.1R against the actual system resistance, electrical connection, fit and environmental limits. This model-specific evidence supports model verification during specification review with fewer ambiguities at handover.
The RE28P-4EK.4I.1R ZIEHL-ABEGG fan is used in HVAC equipment to move air through internal passages and heat-exchange sections, supporting ventilation, temperature control and dependable system operation.
The RE28P-4EK.4I.1R ZIEHL-ABEGG fan is used in industrial equipment where recurring heat generation requires controlled airflow for component cooling, temperature management and stable system operation.
Verify mounting orientation, inlet and outlet clearance, fastener security, electrical connections and the exact dimensional drawing before startup.
Noise data is not listed in the supplied table. Use unobstructed airflow, secure mounting and suitable isolation where required.
Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.
The supplied table lists 450 Pa, 1,440 rpm; use the exact datasheet for the complete operating curve.
