The ebm-papst A3G800-AU23-71 is an EC axial fan for hvac systems, supporting equipment thermal management and integration.
Data includes 400 V operation, airflow up to 26760 m³/h and pressure up to 230 Pa for checking whether the available air delivery suits the installed resistance. The datasheet lists ball-bearing support, IP55 protection, PWM/0-10 V/MODBUS speed control for durable motor support. Listed noise is 74 dB at the stated test point. A suitable electrical match and clean airflow entry reduce avoidable losses and support dependable long-term duty.
Its selection record clarifies technical handover before purchasing approval before the final design-in decision. Its documented ratings also improve traceability during design reviews and replacement planning.
Correct sizing and operation within documented limits can reduce avoidable thermal stress and maintenance events; project savings require duty-cycle analysis.
It can be evaluated for demanding service using the documented ratings, installation limits and preventive-maintenance plan for the application.
Verify mounting orientation, inlet and outlet clearance, fastener security, electrical connections and the exact dimensional drawing before startup.
Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.
