The XG40561BX-1Q012-S9H from SUNON addresses cooling needs in industrial equipment. As a DC brushless axial fan, it creates a defined inlet-to-outlet route across the thermal load.
The SUNON product series carries RoHS compliance and recognized safety approvals; buyers should confirm the approval marks for this exact suffix and target market. The enclosure should direct air across the heat source because bypass flow can reduce cooling even when the fan runs normally.
A dependable XG40561BX-1Q012-S9H installation starts with a review of exhaust separation. Complete airflow mapping for service documentation to confirm compatibility, operating margin and the information needed for repeat orders. Separate discharge air from the intake path inside the finished enclosure.
The worksheet lists 72 dB. Installation distance, airflow resistance, and enclosure acoustics can change the measured result.
The supplied product-line reference discusses long-life cooling, but continuous-duty limits for this full suffix must be verified from its datasheet and operating conditions.
Keep the airflow path clear, secure the frame without distortion, and follow the exact wiring diagram and voltage rating.
Use the listed voltage, size, 34.6 m³/h airflow, 29700/25000 rpm, and 27.6 W input for preliminary comparison.
The workbook marks the product as RoHS compliant. Confirm UL, TUV, VDE, or other project-specific approvals for the exact suffix.
