SUNON PF80252B2-1D03U-S99 brings active air movement to industrial equipment. This DC brushless axial fan helps equipment designers control thermal conditions around densely arranged parts.
The SUNON product series carries RoHS compliance and recognized safety approvals; buyers should confirm the approval marks for this exact suffix and target market. Correct airflow direction and inlet clearance help translate the documented operating point into reliable equipment-level cooling.
OEM teams specifying PF80252B2-1D03U-S99 should check airflow direction and complete airflow mapping before ordering. A documented interface review helps purchasing teams control fit, cooling continuity and replacement planning. Verify orientation so heated air does not recirculate through the inlet.
The supplied row does not state the connector or lead configuration. Follow the model-specific wiring drawing.
Speed-control capability is not stated for this complete part number. Confirm the signal and controller requirements before use.
Its documented 24 VDC rating and up to 96.8 m³/h is its most prominent listed performance figure. allow comparison with the required duty point without assuming unlisted options.
The worksheet lists 44 dB. Installation distance, airflow resistance, and enclosure acoustics can change the measured result.
Verify supply, wiring, obstructions, impeller movement, and protection status. Use the model datasheet before replacement or repair.
