ebm-papst 412H is a DC small-footprint axial fan selected for industrial machinery and control cabinets, where controlled ventilation flow protects operating margin in small-footprint or continuously loaded assembly.
No series-level maximum or certification is treated as a guaranteed value for this complete model code.
The listed ventilation flow of 15 m3/h remains subject to the resistance and recirculation of the integrated installation.
Prototype testing can verify the integrated ventilation flow path and prevent free-air data from being mistaken for in-system performance. Confirm the exact operating point before production release. Preserve the specified ventilation flow direction during assembly. Review the approved electrical interface for the complete suffix.
The supplied files do not establish a universal 24/7 duty rating. Validate ambient conditions, duty cycle, protection, and maintenance requirements for continuous use.
Available performance data includes 15 m³/h airflow, 1.6 W input, 8100 rpm. Obtain the full curve when system resistance or part-load behavior matters.
No quantified cost-saving claim is supplied for this exact item. Compare energy use, controls, service needs, and purchase cost using the required duty point.
The upload sheet marks the item as In Stock, but available quantity should be confirmed when the order is placed.
The upload row lists 12 VDC. Confirm phase, frequency, terminals, and local supply conditions before wiring.
Check supply voltage, controller signals, blocked airflow, contamination, abnormal noise, rotation, and the equipment operating point before replacing the unit.
